UPDATED: Transmeta's Crusoe Unveiled
There's two chips:
TM3120
- Scales to 400 mhz
- .22 micron process
- 73 die-type
- Released: Now
- $65-89
PM5400
- Scales up to 700 mhz
- .18 micron process
- 73 die type
- Released: Mid-2000
- Projected Pricing: $119-329
The chips themselves are 128-bit chips, and are aimed at the mobile market, as TM has said before. One of the incredible parts is their power consumption: 20 milliwatts of power in deep sleep, and 1 watt of power in regular usage. They've written their own BIOS, with Power Management on the chip called "LongRun". The chip actually gauges how much of the processing power that is needed and adjusts the power accordingly, meaning a much longer battery life.
The thermal difference is cool, too - the Pentium III is 113 Celsius, while Crusoe runs at 48 Celsius. That means no fans needed, another power saving move. And my lap won't be as warm. They're aiming this at everything from cell phones to laptops. At this time, they've said that samples have been shipped to "leading notebook vendors" but have declined to name them. As they've said before, IBM is making the chips for them.
What Linus has been doing: He's been writing a version of Linux called "Mobile Linux". It's written into the ROM and you can use the machine through a touchpad screen. The IDE and everything will be released to the Community. Yes, Linux has gone even more mobile. Oh - and Dave Taylor & Linus played Quake to demo it. Linus lost.
The x86 emulation is done at the hardware level - although emulation is the wrong word. We'll have more information on that as well.
We'll be updating this story - the press conference is still going on, but I figured people would want to know. This looks amazing. Check out ZDNet's tech coverage.
UPDATE by David Cassel
What I Saw At the Revolution
Transmeta rented an auditorium on an estate 20 minutes from their headquarters -- and everyone was excited. Walking through the rain -- past the huge lawn, the PacSat satellite uplink, and guys in suits talking into cellphones -- was Transmeta manager Rob Bedichek, who worked on Crusoe's dynamic translator. I asked him how he liked working at Transmeta, and he told me "The first couple of years," I'd wake up and I'd go, 'I have the most fun job in Silicon Valley." On the way into the auditorium I asked him about about the company ("The people I work with are amazing: people whose work I'd read about as a grad student.") and Linus. ("Great guy. Very capable.")
Transmeta had packed the press into an auditorium known as the "carriage house" -- I saw a dozen TV cameras, and I'd guess 150 reporters. A big screen filled part of the wall by the stage, flashing a fast montage of pictures (circuit boards, people's faces) over cheesy jazz music. But when Transmeta CEO David Ditzel took the stage at 9:05, there was a dead silence. "I know some of you have been waiting a while to hear about what we've been doing," he said to play up the tension, prompting a few laughs. "Some of you have been waiting four and a half years..."
Ditzel ran through his Power Point Presentation. (1995. "Something was fundamentally wrong with processors...") and pointed out that the people looking for solutions had been the entrenched semi-conductor companies. Then he announced, of course, Transmeta's "combined hardware/software solution.... The first microprocessor re-thought explicitly for the problems of mobile computing." By now everyone knows that it retains x86 compatibility while allowing a a completely new chip architecture. Ditzel remembered that when he was recruiting for Transmeta, after sharing his plans he'd hear, "If you start this company, I'll quit my job and come join you to do this.
Ditzel ticked off the specs, using phrases like "dynamic translation" and "software-optimized execution," and pointing out that only one-quarter of the functionality would be on the Crusoe chip itself. And there were frequent mentions of the mobile Linux operating system. (More about that later.) Wednesday's announcement was just the first two chips in the Crusoe family: the TM3120 (with 400 Mhz, 108 KB of cache, using 1 watt of power) and the TM5400 (700 Mhz, 400 Kb cache, and 1 watt of power.) Towards the end, Ditzel demonstrated a WebPad -- running Linux -- and pointed out that today's notebooks still use chips designed for servers and desktops. Then he staked his claim. "If it has a battery and a Web browser, it's going to be built with Crusoe."
Ditzel had to stress details for business reporters -- "significant staff" in Taiwan and Japan and "a very strong partnership with IBM -- and later Doug Laird, Transmeta's VP of Product Development, described IBM as "Great guys" and added, "We are in production right now." But I liked one of Ditzel's last comments: "Our goal is to fundamentally change the rules."
Doug Laird was more intense, arguing with current benchmarks ("Today's benchmarks address performance and battery life separately") and promising to show "what is fundamentally different here... Where's the beef." Using a red laser pointer, he ran through taped footage of a system running MS Word 2000 and Excel 2000 on a system with a Crusoe chip, "translating on the fly, as you're running the programs." Then he displayed thermal images comparing processors. (Sensing a photo-op, the cameras started flashing when he held up two "thermal solutions" and started talking about fans...) Laird made his point by showing a Crusoe system using less than 2 watts of power while playing a DVD and pointing out that it can adjust from frame to frame. (The audience laughed at the PowerPoint movie that showed two laptops playing a DVD. Two thermometers showed the temperature rising; then the laptop on the right started smoking...)
Then to break things up, there was the historic Quake showdown between Quake co-creator David Taylor and Linus. "I can't think of anybody better on the face of the planet to demonstrate Crusoe on Linux than Linus Torvalds," Laird joked. The photographers rushed towards the stage again for the even-more-obvious photo-op as Linus came out in his denim shirt, jeans, and sandals. ("I'd like to point out that if I lose, it's not the operating system," Linus joked.) It all ended when Linus fired all his bullets in a spray, then got nailed when he ran out of ammo. (Later in the press conference, after a bunch of questions about his role and Transmeta, Linus referred back to the Quake game, saying it was "meant to show that I'm here, but I'm not supposed to be the main point of it all.") One of Transmeta's technical staffers told me at lunch that "We all knew Linus was gonna get his ass kicked," and sure enough, when I asked Dave Taylor what he thought of Linus's Quake-playing, he said "I thought he sucked." But then he added modestly "I suck at code compared to him. So that felt good."
After the Quake match, the scripted presentation ended and the open press conference began. Linus had worked on the code morphing, but he wasn't one of the execs in this first round of questions. Still, he was clearly on people's minds. Almost immediately a reporter asked what Linus's role was at Transmeta, and then Boardwatch's Thom Stark drew a laugh when he asked when Transmeta would open source the code morphing software. (Since it's considered part of the chip's intellectual property, they probably won't.) And Mark from Linux Journal asked why everything had been so tightly guarded, arguing "There's no demand for secrecy."
Ditzel's answer was that he'd learned the difference between hype and buzz. ("Buzz is when you're quiet and someone else talks about you.")
Rob Bedichek told me later they were proud to have not made promises until they had something to show -- and David agreed. "You've heard what we have here. Today." Right before lunch, Rob remembered that it had been like working on the Manhattan Project. "You don't talk."
The audience wasn't easy. Two back-to-back questions raised the issue of benchmarks (which are answered extensively on Transmeta's Web site) and PC Week asked where their OEM's were. But Ditzel did a good job fielding the questions. He stressed that this announcement had intentionally left out OEM's, to focus attention on the chip itself -- and VP of Marketing Jim Chapman joked that anyways, "I don't think 'contract' is a germane word in the PC industry."
In fact, Ditzel was really building up momentum. I asked him what had happened in early 1998 -- when he was quoted as saying "We had a major change in direction a few months ago, and that has slowed us down a bit." His immediate answer drew applause, and probably the biggest laugh of the morning. "That was just something to throw off reporters.
I'm not sure if he was referring to the same period, but when Linus came on later he mentioned that the first chip didn't perform as well as they'd hoped. But thanks to the code morphing software, "one of the advantages is being able to change the way the chip works..." After some early bugs, "We were able to tell our translation software: Don't do that." He pointed out the chip could easily handle something like the Pentium's famous long-division bug. "Maybe we will have a bug -- but at least we can fix it."
Anyway, at this point, Ditzel was building up so much momentum that the next question was just, "Ask the President to say something." (Mark Allen had been introduced as the new president and CEO for Transmeta, hired just two weeks earlier.) There was a laugh when Ditzel aced the question about expected chip volume. (Was it hundreds of thousands or millions? "Yes.") Chris DiBona asked about the size of the marketing and sales organization (25 people) and as things were wrapping up, someone asked the obvious question about running Windows: does Crusoe *improve* the stability? Ditzel's answer? "If you get a blue screen on another chip, we'll reproduce that faithfully."
Later they brought out Linus, Bill Roses from the code morphing division, Doug Laird again, and three other technicians for the "Engineering Press Conference" -- but during the break, I talked to Rob Bedichek some more. "I'm totally pumped, totally pumped," he said. "This is a big mountain to climb." So how did they do it? "With an unbelieveable team. And an unbelieveable amount of money." (I said I'd heard $100 million, and he said "Well north of that.") Reporters were everywhere -- mulling in clusters out of the rain.
"What do you think of this stuff?" I heard one ask another.
"I think they fixated on a market that's not being well-served."
One of the first questions in the Engineering Press Conference was for Linus, about the mobile Linux operating system that kept coming up in the presentation. It's a "small distribution to give to OEM's so they could have something to run with....not a Transmeta Linux, but more of a vehicle for supporting OEM's." (Rob told me later, "We recompiled Linux for our machine. There's no advantage!") Later Linus added that "It looks a lot better this week than it did last week," and that it "needs some work..." ("Like the chip, we're not releasing anything until it's ready.") Naturally, he specified that it will be Open Source. Someone asked him if his Transmeta job would affect kernel development. "My interests have always affected kernel development," he pointed out. "That's not gonna change."
Linus also talked about how much he liked mobile computing, saying he loves his Gateway but that it takes forever to boot. When asked about how he'd decided to come to work for Transmeta, he described the presentation Transmeta had given him. "I went back to the hotel room and I thought, 'These people are crazy.' And that was a positive reaction. Despite the simulations they showed him "at glacial speed," Linus wanted to work for "a company that does something for and something interesting."
So what were the other job offers that he'd had? Linux companies, of course, Linus answered, but "I didn't want to polarize the Linux market." And Transmeta is a good solution. "We were a chip company where Linux is part of a much larger strategy."
Then he asked the reporters, "Do you have questions for someone else?" (No real surprises; except Bill Roses conceding that Mac compatibility was "theoretically possible.")
When it was over, reporters milled around for the free lunch or crowded into the next building to play with the demo equipment. Basically it was boxes showing the Crusoe chip's ability to run existing software. (There was a Windows 2000 box running Office 2000, next to a Linux box running Quake) and some blue laptops in front of cards that said things like "Ultralight Mobile". But towards the end Transmeta VP of Software Engineering Colin Hunter did show me a neat WebPad using Transmeta boards and software and IDEO mechanicals which let you plug-in attachments for games and cameras.
And with that, as the press release said, "Transmeta breaks the silence."
Actually, cool doesn't quite describe it. Viva Linux!
I'm wondering about emulator programming.. Linus said something about "emulators on steroids". From the various comments, can anyone tell if the processor instruction can be dynamic, done in user space? ie can I pop open a MacOS/ppc vm and have it get the cpu instructions while I run another host os a-la VMWare?
Is that all there is?
I have always wanted a personal secretary that would be powerful enough to run a full suite of financial and office apps on the go, with voice/pen/keyboard inputs and wireless voice/net/ir connectivity. This should help speed that up.
.
It's the code-morphing that makes it compatible right? Or is there some deeper compatibility at the hardware level? Is there any reason to believe that applications written natively for this would be able to avoid the code-morphing layer and run even faster?
Cool. I like the idea of smaller, more portable Linux systems. Just think - the idea of a Mobile Linux PDA. Say goodbye to Windows CE :)

I have this feeling that IBM figured that there is going to be a HUGE need for mobile computers in the future and thought that if they sortof made it look like this new company was coming out and had a great chip that they would make some more money. If you understand where i am coming from atleast. Don't get me wrong, I love the chip, i think it's a great idea, but it reminds me of the Cyrix chip a few years back. Well that's my 2 cents.

bout time they released the specs, damn these sound cool.
I want one of these babies on my desk...very cool presentation. Intel should be scared - Athlon, Crusoe, problems with PIII's Kewl!
I just wonder how successful this chip is going to be. I mean nobody is denying the fact that Athlon is far superior to the P3, but in all the adds from Toronto computer magazines, you barely see any systems running them.
Will this chip have the same hard time to enter the market?
Don't flame me--I have no problem whatsoever with Linus or anyone else finding such a great match between occupation and interest. But I think it's interesting that yet another of those things we all thought we knew was true, wasn't.
48 C is still awful hot! I sure hope that was a typo and really meant Farenheit.
My chip (Celeron) is running right now at 34 F, and that's plenty hot...
I think a P3 would melt at 113 C anyways...
Can someone tell me more about this thing? Specifically, how big (small) is it compared to the existing handhelds? Also, what kind of GUI were they using? Thanks.

Somebody wanna clarify for a non-Linux-user? Is Mobile Linux a functional equivalent to PalmOS or WinCE?

I watched the webcast, and linus REALLY needs to bone up on his Gibbing technique :).
Overall, I am quite excited about the new processor(s), and I can't wait to see who the Transmeta customers are!

Linux programmers can start building software

And what about wearables???? Sounds like somebody
could build a cool computer into a tuxedo! Or would
that be too obvious?
Man this is really sweet. Since it will be able to run any x86 OS, it should make the transition from windows to linux easy for windows user, plus it will make it possible to easily switch between several OS's such as linux, bsd, be, java, etc. Much thanks to Chris for the insightful questions at the announcement. Much unlike the typical question by the woman from the AP who just had to ask about possible IPO possibilities. I can't wait to get a Crusoe
low-cost. This is all very, very good.
Given the mention of the "touchpad screen", is it possible that a Crusoe/MLinux system would
be able to serve as the basis for kiosk-class systems, like ATM machines, information stands,
and so on and so forth?
If the chip is that cheap, and the OS is free, wouldn't it sort of make sense to harness that
and direct it towards those sort of ubiquitous consumer machines that you are starting to see all over the place?

"My karma just ran over your dogma."
that should read 34 C... I wish it ran at 34 F!
Intel must be collectively quivering in their proverbial shoes after this conference. After watching and listening, I am wondering, are we seeing the Next Great Innovation(tm) in processors? The paradigm that Transmeta has created with Crusoe is so different, I have the feeling I was watching a new chapter of the history of computing being written before my very eyes.
What is does under the hood, between it's translation of instructions and its optimization of the actual code (profiling on the fly), is phenomenal.
This Crusoe information is all very incorrect. I can't believe Slashdot was so badly misled. If you go here (http://www.nitrozac.com), you'll see what tech-savvy readers have known for months: Transmeta is building a multi-story abacus. In fact, I thought it was unveiled a month or two ago, but mysteriously disappeared.
they said that they may not release the native vliw instruction set because they want to keep the freedom to change it in the future and don't want to worry about breaking compatilibility.
While this is a good thing in one sense it means
we're limited to only the code morphing software they want to release (since that's native).
So if they don't release code morphing software for PPC, or MIPS or SPARC or ALPHA then you're SOL, you can't write it. And may also be difficult or impossible to write a native version of linux.
Anyone have any thouhgts on this?
Hey IBM what about upgrading my one year old ThinkPad???...please....pretty please....damn...
FIRST POST!!!!!!!!!!!!!!!!!!! MUAHAHA! I really hate to say this because even Linux needs some competition but I wonder whether dear Billy is pondering buying out any chip makers now. Embedding a tiny linux OS onto a chip with incredible potential should scare the hell out of him. Anyone have any ideas on implications on the future of hardware/software now?
It seems hard to believe that they'll get twice as much battery life as existing laptops. I'm no expert, but I'd say that the screen, HDD, DVD drive, etc waste much more energy than the microprocessor. Anybody that knows this stuff cares to give his opinion?
I want one of these things. No, make that two. If they work anything like advertised, they're the best thing that happened since Linus started to code that hobby OS.
Again a tip for those not getting a feed from zdtv, try CNN, works great. It's advertised on their front page.
Will these chips use a standard mainboard, or will they be developed via proprietary means from the various laptop companies? How about prices on these? What architecture is expected - caching, memory addressing limits, etc, etc.

Here I thought it would be a ground-breaking processor in terms of x86 performance... I had my trigger finger on "SELL" for my AMD stock but happily I dind't have to!
Imagine a PIII-500 laptop by mid-year... it's already old hat! Sure, it has good batterly life, but it will only be applicable for the low end.

The way it is going, computers will be at the stage of superiority over humans.
But it might not be really noticeable because we do not have the proper software to utilize it (like AI).
Luckily there is the Great AIP (Artificial Intelligence Project), but if it was not for that not much would be happening

I sure wish I had one of these. If I did I might have been able to get in the first post!
Now I have to decide if I want to wait to get a laptop with one of these on it. Damn.
This also reminds me of the olden days when BASIC was built into the ROM, and would load if no other OS was available. Anyone else ever get the BASIC ROM Not Found error from a Phoenix bios? (Ah, the memories!)
"Live Free or Die." Don't like it? Then keep out of the USA
This doesn't really address what you're talking about, but listening to the engineering briefing, a guy just asked about where the mac os fits/will fit in, and it was stated that code morphing could and possibly would be developed that would allow the chip to handle mac instruction sets. so, i guess this means the same thing for sparc, arm, alpha, etc..
that's what i want to see. screw emulators, i want to see it apps running side by side that are meant for different architectures.
vmware for macintosh? haven't seen that yet - does it exist?
Amiga announcing that they are going to use Linux and concentrate on "internet appliances".. Be announcing that is gearing toward "internet appliances".. Transmeta designs a chip for "internet appliances".. Is it all connected?
I hate to say it, but this is the idea DEC had with FX/32. This is not new, maybe the hardware part?
DEC has always had great technology, not always good at getting it out there
I am glad I didn't buy myself a new labtop... I am going to wait for this. Bill Gates Looks cool as a borg Flames will be sent to /dev/null
Sounds like this could be the beginning of the practical multiprocessor laptop market.
If the chips live up to their hype, I will not have to wait for Wine to run everything I like AND everything the folks at work want.
I want 4!!!
Eve Fairbanks says I drive a hybrid!LOL
Just think of it. This is the closest hardware development is going to get to open source, closer than the opengl and glide development going on right now. Everything software controlled and running Linux! wonderful, wundervoll....
I want to code on this sucker native! When intel are just releasing their first 64 bit chip, Transmeta are releasing the 128 bit chip.
That's an address space of 3.4E38 bytes - enough to hold the complete DNA sequences of everybody on the planet around 3E15 times.
That will be the largest address space we'll need for a very, very long time indeed.
Yes, it sounds like a kick ass product... I listened to the conference until my connection konked out around 1:05. But I was still hoping for more.
According to all the rumors I'd heard, this chip would be able to load many different instruction sets (PowerPC, SPARC, etc...) and always pretty much be running in a native mode.
Of all the complaints I've heard about x86 processors across the years, the one that sticks out the most is that they're a pain to develop for. This new chip does nothing to alleviate that.
In a way, transmeta's become like Be. Be originally set out to take over the world (or at least, the Mac OS market place), moved onto x86 and realized that can't beat Microsoft out of the market place, so they might as well try to co-habitate as well as they can. Transmeta has a really cool product, but has also realized that they can't really push intel out of the market place, so they might as well just aim for intel compatibility...
Too bad it sounds like they expect nothing to be written in Crusoe's native language... There must be some speed improvement that could be gained, if say, Crusoe's achieved 40% market share in the notebook market, that would make it worthwhile for developers to create Crusoe ports.
Everyone is making a big deal about the x86 compatibility. What I want to know is how well it runs code for other processors (which is the whole point of doing everything in software, right?) It would be cool if it could run SPARC or Alpha binaries, because those chips (esp. Alpha) have much better floating point units than x86 processors. (yes I know about K7s. they're still limited by the x86 arch.). Will the Crusoe have a PPC mode, so I can run d.net's G4 Altivec cruncher? hehehe. :-)
Besides the speed factor, x86s use 80bit max floating point numbers. SPARCs can use 128bit floating point. (You get this with gcc's long double type.)
Even more interesting, what is the Crusoe's "native" instruction format like? Is there a gcc that generates native code for it that runs faster? How many registers does it have, or does it even have registers? (maybe just a bit of normal RAM which is as fast as registers, but even less special than the general purpose regs on most RISC cpus.)
I guess all of this will be answered in about 1 minute because the transmeta webpage is supposed to go live around now!

It sounds to me like the real fun is in speculating on what the Crusoe COULD do, or make possible, once various CPU instruction sets are implemented.
For example, a Motorola G4 instruction set software piece could pave the way for someone to sell a handheld/mobile Mac!
Amiga faithful could potentially see a handheld Amiga with a 68000 instruction set component!
Heck, now that I think of it, arcade games these days use various RISC processors, imagine going to an arcade, and renting the use of a handheld arcade game!
Fascinating stuff, I have to say. Fascinating.
Transmeta could make a bundle by selling cheap Crusoe(tm) development systems built on a PCI card. You know we would all get one if they cost
Or, I suppose, they could just create a Crusoe(tm) system emulator program that ran on x86 architectures that would then emulate x86 architectures :-) Of course someone would immediately try to run the emulator in the emulator in the emulator in the...
How come they still haven't updated their web site? I was expecting some change at least...

Are you an SF Fan? Are you a Tru-Fan?
Well I'm pretty amazed that a chip of that speed can take only 1 W of power to run. Forget the mobile market. If this chip does what it is touted to do, having it on the desktop would save tons of power in itself.
What's the significance (if any) of the name Crusoe?
My favorite bit of speculation before today's anouncement was Crusoe being an anagram for source- i.e out of order source.
-ec
another interesting point...
it was mentioned near the end that the vliw instructions AND the code morphing software on the two chips are different and NOT binary compatible.
So possibly no Linux on the 700Mhz version?
(they said it's optimised for 16 bit x86 instructions)
Just think of it. This is the closest hardware development is going to get to open source, closer than the opengl development going on right now. Everything software controlled and running Linux! wonderful, wundervoll....thanks a lot Transmeta, but I really hope the release the code...
In all the reports I've seen so far the 5400 has been described as a "windows chip", and nothing is said about Linux. Naturally I assume that anything that can run Windows can run Linux too.
Life's a bitch but somebody's gotta do it.
In the Q&A he asked, "Since Linus helped to develop the chip, it is Linux-based. Will it also run Windows?"
This, after an hour of presentations, including running several demos of Windows apps (including Quake), references to the fact that they have tested 30 OSs on it, and a myriad of references to Windows specifically.
The "mainstream" press is missing the point. I'll bet they label this an Intel-clone from Linus and the public will yawn.
I have a "Zero Policy" tolerance.

I appologize if this has already been addressed. Alas, my connection to slashdot is poor and it took forever to bring up the reply page.
I see that this processor comes in two versions with different Mhz, but what does that actually mean in real world performance? What is a 700Mhz or 400Mhz Crusoe chip equivalent to? As we all
know, the Mhz rating does not mean everything.
-OT (bogomips for everyone!)
Lack of the native ISA also makes reverse engineering their emulation software harder... of course a patent should provide all the details needed to implement that anyway :) (it hardly ever does)
And if they worry about compatibility license the information, make it usable only for GPL software. With source backwards compatibility on the instruction level isnt much of a concern.
So why are there six toeprints in the image on their homepage? Is this another hidden message?
Its up now (12:05 PST) and it looks good. Though it is very, very, very slow! What... didn't they expect to get hits?

** Evil Canadians are taking over the world. Learn about the conspiracy
they should have spent a bit more time on bandwidth and their server machine while everyone was hyping the product....11:59 PST, normal site, 12:00 PST wow, new site, click on one link and realize its been slashdotted....
did they think they'd get a small number of hits?
ugh
I'm not going to wet my pants over this, frankly, it doesn't sound all that amazing.
Then again, I don't get excited when Linus takes a dump either.
Dr Fgets Strikes again!
Can u imagine gutting a palm V and dumping a crusoe into it and running Win2K? Why? Why not?
Technologically, the Crusoe is a marvellous little device. May be the catalyst to replace our desktops with slimline portable embedded devices.
But there's a serious flaw I see with all this grandstanding and fanfare...
It sounds to me like Transmeta is going to focus on their ability to emulate the x86 isn set atop a vliw processor. That's all well and good, but I thought they would focus that as a "feature", not a mainstay of their product. I am disappointed to see the archaic and outdated x86 architecture perpetuated by what I once thought to be a high-tech company on the bleeding edge. AXP, sparc or even MIPS has a better architecture than the x86. Their promise to not release the native vliw instruction set solidifies my opinion against them.
The Transmeta site is understandably slow now. With not only all of /. going to check it out, but many people reading ZDNet, MSNBC, and others, as well as other people in the know, it seems their server was not ready for the traffic...
---------------
Yes! That guy!
Ditzel, a former engineer at Sun Microsystems, was integral in the development of the RISC processor, another competitor for Intel's x86 processor. RISC was faster than Intel's chips, but software designers never picked up on it, and it remained on the fringes.
I sure hope the Crusoe does better than the RISC!
That damn time machine set me back 15 years!
My chip (Celeron) is running right now at 34 F, and that's plenty hot... That's 2 Degrees above freezing. Room temperature is already around 75 degrees average.. so just sitting there that'd be the temperature of your chip. With power flowing into it, the temperature rises.. even with a fan. The fan is blowing 75 Degree F air acrossed it, so the temp won't be below 75F. Unless you have some refridgerating system hooked up to drop the temperature to 34 (and in which case unless you had it setup right would cause water to condense on the chip and.. well you know how electronics and water work together). I believe you either ment 34C or you're just damn stupid.
So now that mobile Linux has been demoed to the world, when is Linus going to release the source? I didn't hear any mention of it during the webcast (although I had to leave part way through). And I guess the other question is, is this a kernel fork in progress, or is it a common kernel with what we've been seeing in development right now?

Well it is, theres other high mips/watt architectures wich are probably competetive. (especially considering the advanced process wich crusoe uses)
The real innovation as you say is the code morphin, but IMO binary compatibility is becoming less of an issue in the future not more.
Hmm, my pIII 450 overclocked to 600 runs at 65C, and my G3/350 (copper 750L) runs at 31C..
:P
How come Crusoe runs so hot compared to PPC?
I guess IBM still have an edge on the old-style static register cpu's anyway
According to this article: http://www.zdnet.co m/zdnn/stories/bursts/0,7407,2423907,00.html These processors are not designed for Palm devices but for other "mobile internet devices". Interesting, perhaps this is due to the existence of low power CPUs in the market already. It would be cool to have Mozilla running on my Palm though.
I keep reading that the TM 5400 will be on notebooks running Windows. Was it announced this way for marketing purposes or will it also have the ability to run Linux?
ARM Linux on the SA-1100
While the SA-1100 doesn't have the cool code emulation bit, it does run at 200+ MHz at half a watt. The chip also includes vga, irda, and audio codec support. All of that for a half-watt, max.
I still think the Transmeta announcement is cool, but not because of the low-watt linux claim.

instructions in software rather than built into the hardware? isn't that basically what a winmodem does? ;-) now all the non-windows, non-linux using crowd can complain there are no drivers for this hardware ;-)
NO CARRIER
Why? Just because Linus works there?
Intel has shown more support for Linux as Transmeta... Intel's hardware is open, seems like an easy choice from a principle POV.
My concerns are this:
since it is maintaining compatability with x86 instruction sets, it will always follow Intel's lead (and require Intel to continue leading) mainstream chip technology.
It will never run as fast as a native x86 chip would (because it must execute extra instructions). Of course, being smaller and independent to the hardware, these chips may be made significantly faster (clock-wise) than mainstream CISC/RISC chips and comparatively match performance. But not yet.
No mention was made regarding the connection to the Internet...that was just assumed to be there. But I have yet to hear about any affordable and sufficiently fast connection via mobile unit... How will they address this, or will they just leave it up to other companies to solve this general problem?
Transmeta touts Internet Compatibility, but the low end Internet appliances are specifically designed to work with Linux. However, Linux does not have a standards-conforming browser (i.e. IE) available until Mozilla is complete. Will Transmeta help push Mozilla to completion? The specific mantra was, "You have to run the cool site of the day" but many sites are becoming dependent on HTML 4, CSS2, DOM2, ECMAScript 2, etc., which, sorry, only are supported to any extent by IE5. How will Transmeta maintian "Internet Compatibility" with Linux-running machines?
One correction to Hemos, however, Transmeta specifically said they are not targeting cell phones and Palm Pilot-type machines, but rather full-blown Internet compatible multimedia machines (which may be small, but no compromise on feature set).

My guess is that this is who they will make their ongoing cash. Charge u for the updates to the processor and let other ppl worry about the end user apps.
.oO0Oo.
I think their answer about backwards compatibility is a fudge. They said it was so ppl didn;t have to re-compile but it's hardly thw worlds gr8est problem to those ppl who know about such things.

Transmeta talked strictly about mobile computing, but what about desktop systems based on this thing? Low power consumption there is good for the enviroment, and good for the electric bill. Also, it would seem that this thing could be programmed to be other, non-x86 (or is it IA32 now) CPUs. It would be great to have a portable Sparc book, without paying portable Sparc-book prices! Or my dream machine... You can select PPC/x86/Sparc/Alpha at bootime, and boot an appropriate OS.
That would give a whole new meaning to the concept of a computer in the refrigerator.
my question is what kind of mainboard does this thing have since it runs x86 right now is the mainboard x86 or is it some propritary thing and the code morhping software handles all the requests to the video and IO systems and stuff also couldn't the mainboard be a problem if you say wanted to run say PPC instructions on it, since x86 and PPC boards are different, or does the code morphing software automagicly translate all OS requests into native VLIW instructions and so forth so the main board would basicly be platform independent?? or am I totally bonkers?
I'm sorry, 1W descibed as 'incredible' power consumption betrays a serious lack of perspective. The ARM7TDMI consumes 0.6mW per MHz on average (note the 'milli') and these usually run at 66Mhz! That's less than 39mW for a typical processor. 1W means squat until we see the performance figures for this thing. I don't see it making great waves in the mobile device sector unless the power consumption is drastically cut. And what's this about hardware x86 emulation? Have we been tricked by the pre-release chatter? Everyone was talking about this thing being software driven on the emulations side. For now established RISC-based processors don't seem to be challenged.
Does it run Linu...
Oh, wait, I guess it does.
Okay, I guess I'll ask the next-to-important question:
How does this help me get chicks?

x86 processors are known to be particularly bad from the power consumption standpoint. When the Pentium II was first launched, it consumed something like 40 watts! There have been several die shrinks that have helped to reduce that quite a bit. I think the typical "maximum" power budget guidelines for a notebook computer is 10 watts for the CPU - the mobile Celeron, PII and PIII CPUs probably come in right around that amount - maybe slightly more 15 Watts or so.
Now, you look at this Trasmeta CPU that consumes 1 watt of power - that's quite a big difference, like 1/15th the power consumption. (FYI - its not like they are the first people to do this, the DEC StrongARM is a RISC chip that has similar low power consumption - 1 watt or less depending upon operating speed.) What I am really curious to know is how "cut down" is this CPU in order to achieve that power rating? For example, the StrongARM achieves that low power rating (in part) because it leaves out a bunch of processing units typical of a desktop CPU - eg it is integer math only, no floating point unit. My suspicion is that Transmeta must be doing something similar to achieve this.
As another power benchmark to think about - the PowerPC "G3" chips consume in the range of 5 watts - and these chips have all of the "standard" units (both integer and floating point) - the thing that they do NOT have is instruction level compatibility with x86. The G3 has similar performance to a PII / PIII class x86 CPU so you could infer from this that the PII / PIII must be burning up all that extra power in translating x86 instructions to its native RISC ops in hardware.
At any rate, it will be interesting to see what exactly this Transmeta CPU does and does not do to achieve such a low power consumption.
Also, you are correct about the LCD display - the CCFL backlit active matrix LCDs typical of notebook computers are also a major drain on the batteries as is the hard drive though often the hard drive can spin down and "sleep" unless you are constantly hitting it for virtual memory or something.
-Linus got his ass kicked by Dave Taylor (co author of doom and quake) not the CEO. But the quake3 performance was great if they didn't have a 3d graphics card in there. (i.e. is was running in software mode).
- The code morphing software WILL NOT be open sourced. It doesn't have to be it's not part of the linux kernel. The code morphing software sits below the kernel translating the x86 instructions into vliw.
-They will release the "Mobile linux" source code but it looks like all that is is a low memory optimised version of linux with power management and an onscreen keyboard application.
Nothing earth shaking there.
But hell, I still want a linux webpad.....
what about desktop?!?
. . . it sounds like Transmeta will definitely NOT be releasing the info needed to code directly against their hardware. Their argument hinges around the fact that the two chips they have today both have different code requirements -- so if they let you write directly to the 3120, your code wouldn't work at all on the 5400.
Moreover, they expect to continue this state of affairs. The result is that if you coded directly for any given Transmeta chip, you'd be writing stuff that didn't work on any other Transmeta CPU.
Which, naturally, they view as a bad thing.
Toward the end of their answer to that question, the CEO did hedge a little, so it's still possible that they'll release the info needed to go Native. But it doesn't sound likely.
. . . or that's what *I* thought they said . . .
I have no
Personally I've always wanted one weak enough to give into tempation, come into my office suite and be ready to go, have at least three inputs and a beeper so I could connect whenever I needed =)
Before you moderate this down (and I couldn't blame you) consider that the thought crossed your mind as well;)
Someone mentioned that it could emulate 'any' processor architecture.
Why not have 3 - 4 CPU's in one machine, each emulating a different architecture? Have a hardware switch to swap between them. They have seperate memory blocks but in the same chips.
Or instead of swapping between them, just slice the screen up into as many sections as you have CPU's and have the mouse live in 'limbo' above the seperate OS's, meaning you don't have to swap from one to the other,they both exist at once on the screen and the mouse can move between them freely, dragging/dropping data where applicable.
What do you think?
A processor for wich its instruction set isnt even given, I can only see it as a step back.
Sorry I really dont see your POV, please explain.
A lot of media hype (a very well managed campaign) and then ...
...
... Red rag to a bull time!
... well nothing really.
They're offering processors which scale well underneath the next big batch of processors from Intel and AMD - and don't forget these Transmeta boys are talking about 0.18 micron so they're gonna have to wait a couple of years to scale to next level. Given that the big 'zillas seem to be releasing new devices every month at the moment I think this little lot is much fuss about nothing.
As for mobile devices - well frankly nobody really cares if they're x86 compatible.
Mobile = v.low power, and last time I looked that meant 1W . Something like the ARM
Even more ironic is that with the advent of Linux we're seeing lots of cross platform libraries and technologies. Beating the x86 problem is old hat.
What this might have been really nice for is a 'native' Java chip.
You also have to laugh when they say "There's no way a hacker is gonna get into this baby"
A question: because of the Crusoe code morphing technology does this mean that we could program it to translate Java byte code into the Crusoe VLIW instruction set and get a hardware speed JVM? That would be sweet...
Hotnutz.com
They may as well bend over and kiss their arse goodbye.
everybody's saying intel and amd should be quaking in their boots right now, but i doubt even the greatest of expectations coming true could make intel sweat
i'll tell you who should be concerned - motorola. ibm's been slacking on the ppc front as of late, concentrating on their own ppc variants, and not the altivec/g4 roadmap moto laid out.
if crusoe can do the heretofore impossible - emulating ppc and running ppc native instructions as fast as a real ppc core, and it seems to take even less power than ppc, it would give the limited risc os market a new place to turn when motorola screws up production again, as it did on g4
that means next gen amigas, ibm power iron, even macs (!) might take advantage of crusoe to run cooler, faster (?) and cheaper - not to mention have more compatibility to run non-ppc binaries or OSs.
speaking of mac, why would apple bother to do an x86 port of osX, which has been rumored for quite a while, though never seen in the wild, when they can just optimize for ppc, and tell everyone who wants to run it on non-ppc to get a crusoe?
- Entertaining Bits from the Ancient Kernel Tree
Been in development for some time, but secretly. (Didn't hear a word from Sun until it was practically complete)
Has the idea of trying to remove backwards compatability hardware problems and issues. (Crusoe with code morphing, MAJC with Java). This makes it much easier to really optimise for each generation.
VLIW type design. Sounds like Crusoe is fixed 128bit - like most designs. MAJC is variable - 32-128.
low power embedded markets. However Sun is more "embedded" than low power (MAJC 5200 is 15W @ 500MHz), but Sun are going for some pretty damn serious performance - eats mutliple MPEG2 streams for breakfast, 100 voice of IP channels at once, or 50-90M triangles/sec for 3D lighting/transform etc - the PlayStation 2 "Emotion Engine" is a similar product (in terms of performance, power, cost) but is rather more conventional.
Both using IBM fab. Both 0.22 initially, and 0.18 later. (Sun are using copper interconnects, I guess Crusoe is too)
The point about doing benchmarks for the Crusoe discussed in the annoucement is quite apt too - with Java HotSpot, the longer you run it for, the faster it gets. Normally, you use a real application for minutes or hours, but most current benchmarks don't run that long, so isn't quite so "fair".
However, Crusoe beat MAJC to being fabbed and sampled. (MAJC should have "taped out" by now, though no official annoucement yet)
Different markets (MAJC doesn't execute x86 for one, but maybe they could add it later...), though there is some overlap - I think both are going to be very interesting to watch. Both bring some interesting new ideas and applications of things.
Some architectural differences: Crusoe could do just about any instruction set "directly" through code morphing - you'd just have to code it. However, don't expect them to do many as it would be a huge amount of work for each instruction set. They can also do more than one at a time. Though MAJC is not a Java bytecode executor (and you could port Linux to it as easily as a typical RISC CPU) it only does it's instruction set. They hope to use Java to make things more "portable", which is a lot harder than the code morphing techinique which is basically transparant. Not much details has been given about the Crusoe engine, so it's hard to compare, but it doesn't yet seem like it has hardware/vertical threading support, or chip level multiprocessing support (more than one CPU core on one chip), for example.
MAJC does have this one thing which similar in terms of complexity and mixing hardware/software though. When running a JVM, you can use a mode called STM (Space Time Computing) which uses more than one CPU to speed up a single threaded Java app (using some interesting thread speculation techniques), which like the Crusoe code morphing engine, is transpart - you don't need to compi
I think I should explain something. What does 128-bit VLIW (Very Long Instruction Word) processor mean? It's not about register size. Neither about data or address buses size. It's instruction word size. The processor itself is probably 32-bit since it's supposed to emulate IA-32, but it could be 64-bit. some numbers: 8088: address bus size:20 data bus size:8 register size:16 instruction word: min=8 max=64 ??? instructions / cycle =~ 0.1 i486: address bus size:32 data bus size:32 register size:32 instruction word: min=8 max=120 instructions / cycle =~ 0.7 pentium: address bus size:32 data bus size:64 register size:32 instruction word: min=8 max=120 instructions / cycle =~ 1.3 K7: address bus size:32 data bus size:64 register size:32 instruction word: min=8 max=120 instructions / cycle =~ 4 crusoe: address bus size:? 32..36 ??? data bus size:? 64 ??? register size:? 32 ??? instruction word: 128 ! instructions / cycle = 3..10 (integer value !)

Does anyone know where there is a archive of the webcast? I looked on Zdnet's site and didnt see it. Thanks
I have to return some videotapes...
Cant really run DVD though unlike the Crusoe :) But once Strongarm hits .18u it should own...
Linus said in the webcast that Transmeta made a mini Linux distribution for its licensees. However, if the licensees could not publish that GPLed software without violating their NDAs with Transmeta, then the GPL forbids Transmeta from distributing that Linux. It doesn't say anything about whether the licensee wished to publish or disclose, nor does it say that the NDA must be amended, it says "if" and "refrain". Hey, I'm not gonna call 'em on it, but what do you all think? :)
Quoting from the GPL (and careful, don't confuse the example they give with the principle):
Is Transmeta going to publish the architecture so that we can make a native Linux port instead of running x86 Linux through the interpreter?
A few things struck me with the press conference:
Linux, when asked what his future responsibility at Transmeta will be had to stretch for an answer. Normally this should not be a difficult question for anyone -- you tend to know your job. A job description of "whatever they tell me to do" does not inspire confidence.
Linus also stated that Mobile Linux was just plain old Linux. Nothing particularily new or exciting.
My cynical take on all of this is that Transmeta hired Linus because they wanted to inherit all the hype and excitement surrounding Linux. If Linux is the newest coolest thing, surely hiring its creator makes the Crusoe the newest coolest thing by association alone. If this was the case, it sure as hell worked. Every member of the cult of Linux has been drooling for months over what their guru was working on behind those closed doors.
Quite a nice deal for Linus though -- being paid to do what you love in return for generating hype.
I reviewed the cnet article, which is pretty good in most respects. My notes:
- There is considerable focus on the processer clock speed, without mentioning the fact that it morphs instructions to run them. This reduces the number of instructions, and therefore clock ticks to complete the same amount as a 'traditional' x86 processor.
- They make no mention of the fact that the processors aren't necessarily competitors only in the x86 market. They can run many other processor's instruction sets.
- Interesting that they didn't mention the Linus/Linux link to Transmeta and the fact that Linux has already been written specifically for the platform. Also, that the 5400 will run Windows but is not yet in production. Interesting.
Overall, a pretty good article.
Hello little man. I will destroy you!
Well, I was going to buy a Handspring Visor (running PalmOS) but I guess I'm waiting for one of the Crusoe processor based systems now. :)
Handheld Quake. Three words: Cool as hell.
Judging by the following URL -
http://www.transmeta.com/mobile/
Looks like someone at Transmeta likes Slashdot, too.
The Webpad shown at the Transmeta Site about the mobile products shows Slashdot on the screen.
First, let me say that the chip looks mighty cool. However, I was very disappointed in their not releasing industry standard benchmarks.
While I understand their wanting to show their big power advantage, trying to mix two totally different measurements such as power consumption and performance into a single rating is the height of marketing bulls**t. But OK, if they want to, that's fine.
But not at the exclusion of real performance benchmarks. Show me the components that went into the bulls**tmarks or whatever your new benchmark is.
At one point during the Q&A, someone made this point, and the engineer dude (can't remember his name) said that a 667mhz Crusoe performs like a 500mhz P/III. *cough* I'll believe that a software-based emulator can get 75% of native hardware performance when I see real benchmarks. Until then, all this handwaving makes me very, very suspicious.
All this having been said, the screens flashed by pretty quickly, so clearly it's not a dog. But Transmeta: if the performance is good DON'T HIDE THE NUMBERS.
---
So this is it?
I must admit I'm slightly disappointed after all the hype and excitement. There's no revolution goin on here, folks. Just a small step of evolution.
Bleh.
when all is said and done that is all we have here. ultimately the success or failure the company (as ever) rests on the market for this product. oh, and how the major competitors can crush it.
the technology implemenentation is nice - transmeta can easily address instruction set changes by intel & amd simply - and fix any bugs they have via firmware upload. however, the ultimate performance of the chip might not be as high as 100% silicon (but for a mobile market, this is not so important). as the silicon is simple and cheap, transmeta are likely to be able to handle lower prices from competitors.
the hardware approach is interesting. a full VLIW design. these things never took off because any hardware change means rewriting a compiler and compiling *all* application software. not really acceptable! but as this one only ever runs one application - an x86 emulator - the problem goes away. transmeta do absorb writing a compiler for each chip generation, as it is part of the CPU development budget.
sun's MACJ is similar in philosophy, being another VLIW. that is more of a traditional processor in that they will preserve the instuction set across generations. but in that case they are really aiming to run a VM on it - Java in that cae, rather than x86. it's a different beast, but perhas trotting in the same direction.
but please remember guys that it's success depends on the what it is. a low power, low cost x86 clone. it saves you a fresh battery at mid-day. so in the scheme of things it is not so exciting.
an ARM (and they admitted this) uses less power.
The TM 5400 is optimized for Windows but it'll run any x86 OS.
The neat thing, that I haven't seen anyone here pick up on yet, is that the Mobile Linux based web pads, etc, will have about a six-month lead over any Windows-based Crusoe machine -- that is, if you want a web pad (and they are cool looking machines), you get Linux. The 3120 is in production now, the 5400 won't be for another few months. (Oh, I suppose some manufacturer might decide to do a Windows-based machine on the the 3120, but it'd be more expensive: Windows license cost, hard drive for the OS (the Linux is ROMable), added development cost).

Maybe with the right code-morphing softare it can emulate the PalmOS. Or even run the Palm GUI on top of Mobile Linux kernel. Maybe? Pretty please?
Hmmm, a 400 MHz Palm Pilot. Maybe I'll try that color screen after all.
Does this
PowerPC was nice, but they never ran the old 680x0 code worth beans. Wheather or not Crusoe is the "Pentium/Athlon Killer" rests on how fast it runs in x84 emulation/translation/whatever-they-wanna-call-it mode.
Can someone explain what the diff between this code morphing and an emulator written in assembler is? Is it that the emulator binary is loaded into a fast on-chip cache, or something?
http://www.userfriendly.org/cartoons/archives/98de c/19981201.html
Theres good arguments to not do a native version of windoze for it, the arguments for Linux are bunk. They decided not to release the instruction set, the fact that we wont see a native Linux is a result of that not the other way around... pity Linus has resorted to just towing the company line.

I have to return some videotapes...
Seeing how that appears to have happened (like we ever doubted it wouldn't!), the pdf docs (the important stuff) has been mirrored at http://printf.net/transmeta/
Power consumption of the chip is lower, but power consumption of the chip is only 20-30% of a notebook, limiting the value of this "revolution."
Further power reductions require either A) giving up a hard disk (aka Linux in ROMs) or B) integrating more than just the CPU and chipset (what about 2D/3D just for starters, not to mention sound, fast ethernet, modem, wireless etc.; note that some of these require analog circuitry not just digital and pinouts start getting complicated)
Sure, Intel's SpeedStep power circuitry is less dynamic, more of a step-function static approach to power management. But is it good enough? If not, will the next generation of their technology in 2-3 years be good enough? Not much of a market window here, in the big scheme of things. Remember, Intel only loses when CPU power is an issue; it can pursue the same no-hard-disk and system-on-a-chip approaches as Transmeta. No patents there.
In terms of integrating 3D, Intel has a huge lead over Transmeta in terms of patent licensing and technology development.
So what about Transmeta in the embedded space, a la cell-phones? This appears to be a backup strategy not articulated yet for one simple reason: the TM processors are still less power-efficient than, say, StrongARM.
Did I mention the difficulties Transmeta would have keeping up with Intel's clock rates and performance? There's not a clear win here today, and this is only going to get worse before it gets better. It's relatively easy to release one innovative product that hits the market sweet spot once; it takes a totally different set of skills to keep up development of an ongoing stream of products that is always competitive with what's in the market. You can see this in the 3D space over the last four years, and AMD also illustrates the ups and downs of playing challenger.
Wireless internet is cool, but I find it hard to be optimistic about the per-month pricing over the next 3 years at reasonable bandwidth rates attracting serious (5+ million) consumers. Guys putting up towers and satellites are the bottleneck here, as is the degree of competition.
;-)
This is all very innovative, and perhaps Transmeta OEMs will sell a few million units of handheld notebook/palmtops, with Transmeta gaining reasonable market share over the short term, IPO'ing to incredible hype, and three years from now realizing that well, they don't have the market position needed to really compete when Intel puts the squeeze on. Their technology value-add that I've seen is too slim that it can't be embraced and extended by some means. I see enough value add for them to survive, to live well and cash in on some sweet stock options, but I don't see them becoming a big or significant player 5-10 years out. Long term, well after the IPO and honeymoon period are over, they only make sense combined with someone like AMD with a much broader product line and established consumer reputation.
How's that for thought provoking?
--LP
- Reference machines...
- The Code Morphing piece -- raves here!! It received a brief mention at the end, but if Intel, etc. add an instruction to the x86 set, Transmeta can use the CodeMorphing piece without requiring a new fab mask to be redesigned into the chip.
- Full x86 compatibility, with two different models. The more expensive, faster chip will support all x86 apps including 16 bit ones, the less expensive one dumps the 16 bit because (as Transmeta made clear) there really isn't a set of legacy apps out there.
- The LongRun design -- which automatically sets the chip(s) to use power maximally well.
- Showing Transmeta chips running both the Windows version and the Linux version of Quake concurrently. 'Course, Linus coulda used a bit more practice before the demo, but at least he mentioned that when he lost, it reflected his skill and not that of the OS...
;)
I expect this chip to succeed big for reasons mentioned in a previous post.What this means is that Transmeta does the R&D for a device (such as the web pad which they displayed), then provides the specs to manufacturers, who can then produce them without requiring startup R&D to design and build Crusoe based machines. Smart move.
I like this alot -- if I'm really committed to Linux, why would I want to be stuck with the overhead from what was originally a fairly bad chip design (8088,8086 up to 80386)?
...Open Source isn't the only answer -- but it's almost always a better value than the alternatives...
Not being a technogeek but a geek-of-all-trades wouldn't it be more powerful to have a single device with these cheapo chips and Linux's SMP? Am I stating the obvious or the ignorant.
In my imagination I would like to have a multi-TMchip pad with pen and vkeyboard. An engineer could carry a full-blown 3d & raytracing CADD package one handed into the field rather than a bulky, shortlived notebook. (Provided mainboards or the equiv are dev'd.) Hell, at this kind of price (which will drop) why not have four or eight in your desktop. So what if 400MHz is slow right now? That will go up.
IMHO this part of the GPL can be worked around temporarily by being very careful in what the contracts between (in this case) Transmeta and the licensees say. One way might be to state "we'll make it for you now and you can come and inspect it and play with it at our premises, but we will only deliver the product to you on January 19, 2000 etc."
Beware: IANAL.

Wimps! It hits 48C (even 50C) a few days during summer here in Las Vegas, Nevada and 40C can stick around for many weeks in a row, with temps not going below 30C even at "coldest" time of the night (just before sunrise)! And as the A/C breaks from time to time, I have to worry about how CPUs will run in ambient 48C air, which the ads for chips/PCs never tell you. Crusoe will be a godsend for desert dwelling geeks like me,if it runs as cool as its specs say it does.

Being one of a few (if not the only) negative poster, I'm likely to get branded (and moderated) as a troll/flamebaiter, but please hear me out...
I'm wondering if I watched the same presentation as the rest of the posters here... Deitzel and co. effectively skirted the performance/Mhz question, which says to me that they don't have much to brag about in the performance area, otherwise- They would've bragged about performance/Mhz.
I could've sworn I was watching an Microsoft/Apple/Intel love-in/press-conference at times. A quote of note: "Crusoe will be a low power internet platform for the future". What the fsck does that mean? There was lots of 'marchitecure', but little in the way of hard performance numbers.
Looks like Transmeta's smartest move was to hire Linus, 'cause the whole of Slashdot is believing the (and feeding) the hype without knowing all the facts.
There's an interesting double-standard on slashdot... Announced and unshipping products that are !linux are vaporware, yet announced and unshipping products that Linus smiles on are "the next big thing" and "A new paradigm in computing".
And they say Mac advocates are fanatics...

So, if what's going on is that instructions for an x86 are being translated on the fly into instructions for Crusoe and this is done so well that there is a marginal difference between using the actual Crusoe instruction set what does this bode for independent byte-code implementations of Java etc? Doesn't it open up the possibility of keeping libraries of pre-compiled, pre-interpreted , ANSI C, on the hand-held, then a nice little dynamically compiled x86 gets sent over the net, looks up it's stubs locally and away it goes? Am I being really naive here? (Actually, I don't want an answer to exactly that, I want to know what my naivete is !. I suppose there would be security issues.
...or have the moderators been smoking crack recently? Maybe the moderators should read the article before moderating. How was that offtopic? (Hopefully its been fixed by the time I post this.)
To respond to yours - yes, I think this is the next generation, but only for wireless computing. I really don't know what to make of it as far as computing in general goes (nobody ever knows where computers will be in even 5-10 years)... Given all the big names Transmeta has, though, I imagine it will at least be phenomenally successful amoung tech junkies. It sounds incredible and I figure it has to suffer somewhere because it sounds too good to be true (don't let me down, Linus!). Maybe its really expensive? Well, I will have to buy one of those webpads so I'll find out soon enough how nice it is.
Perhaps the revolution your referring to is the one (insert name here - forget where I read it, probably a Crichton novel) was talking about when discussing ultimately "invisible" computers - when computers are in everything and we don't have to think about them anymore. Different "computer" tasks will be handled by miniaturized devices whose sole purpose is to browse the web, or check your email, or just make your coffee exactly the way you like it. This new chip could potentially help set such a trend in motion.
I haven't reviewed the spec sheet yet, but I understand the chip uses one watt of power. Well, I think transmeta might be out to make this chip look better then it really is. When running electronics off of batteries, the watt rating doesn't matter (W = V x I). So you can have a high electical drain an a low voltage and still come out at 1 watt but your batterys wouldn't last long due to the current draw (I'm hoping its more like a low current draw and only uses a few volts and comes out at 1 watt). Can anyone that has the spec/data sheets on it tell me what the milliamp hour rating on it is, so that I can get a better picture of the actually battery life on this chip?

And here is an example (quote from the datasheet for the 400MHz processor):
Other than having execution hardware for logical, arithmetic, shift, and floating point instructions, as in conventional processors, the Crusoe Processor has very distinctive features from traditional x86 designs. To ease the translation process from x86 to the core VLIW instruction set, the hardware generates the same condition codes as conven-tional x86 processors and operates on the same 80-bit floating point numbers. Also, the Translation Look-aside Buffer (TLB) has the same protection bits and address mapping as x86 processors. The software component of this solution is used to emulate all other features of the x86 architecture.
So all the people that were thinking about 128-bit floats are SOL. I think that emulating non-x86 architectures on Crusoe is going to be possible, but noticeably harder and slower than x86.

I am thinking that this processor / platform could end up being the ultimate web server. Built in Linux stuff, ultra low power consumption. It all means that you can build an ultra small, ultra cheap, headless web server that can probably be powered by a medium sized UPS for like a day in case of power outage. Think of the amazing density you could get out of a server farm.

"For the Snark was a Boojum, you see." -From the Hunting of the Snark: An Agony in Eight Fits, by Lewis Carroll
Personally, I've always wanted: One, week enough to give in--two, temptation! Come into my office, sweet, and be red; eat to go; have, at least. Three, input-sand a beeper. Sew I could, connect wen ever Rhiney dead.
my guess was that the native instruction set might just be held under wraps until it settles down. the two chips so far revealed differ in their optimisation, for example (the 5400 is slightly better suited to running 16bit code), but once you reach the abstract layer of x86 instructions they are identical.
with this approach nobody writes code for the VLIW instruction set, so nobody cares if they change it to something entirely different next time around when they think of a new hack.
From my understanding, variable speed CPUs (used on many laptops) that throtle up and down freak out Linux. If crusoe does this, Linux must have resolved this issue.
It's only redundant if you can actually read it already. Given the 20 min laggin g I'm getting on each page, I'm sure it's out there by now. I pity the fool.
Expanding a vast wasteland since 1996.
I just thought of something -- this new chip is rather cheap (considering Slashdot figures are right); the chip consumes very little power, it is nonetheless fast and needs no fan.
It's perfect for Beowolf-type clusters. Just think about it -- cost is lower than with other chips, less power consumption, less noise, etc.
Perfect.

Have a good one.
The only real code written to a specific chip is a compiler backend nowadays... its clear open source is not a Transmeta concern.
If I have the source and a native compiler I could give a toss about what processor Im running on.
I have the suspicion that its just a way to more closely protect their translation code.
I tried to goto www.intel.com and look at how
the 1 watt power consumption looks compared to
the Intel Celeron.
Unfortunaly, Intels web designers decided that

Did anyone else notice the screen on this webpad?
...so I can replace the "powered by AMD" icon on my web site. (no Intel product will ever enter my home. Intel *always* runs too hot.)
B. Low Power Consumption. Yes, lower than x86. But, not lower than other architectures like the ARM. They acknowledged this in the webcast.
C. Compatibility. Yes, x86 compatible. I can dual boot it between Linux x86, NT, Win98. My Celeron does this today.. wow.
What we have here is an x86 processor with good power consumption. In the webcast they were saying something around 20-30% better power consumption than existing chips. That's nice, but not exactly revolutionary..
I like what I hear, and what I read between the lines with the Crusoe family of processors.
It's too bad they are not making a chip for a Cellular phone or Palm-like device, only HPC and larger form factors. One device that would really benefit from such a chip would be the Nokia Communicator line... that would kick some serious tail.
Things I'm excited over:
1) The Code Morphing Software (CMS): enables the user to have any x86 OS on the HPC, not just windows. Also, they can make a CMS that emulates SPARC, Alpha, etc - very cool. The optimization of the code on the fly, and with a translation buffer - very cool - plus, performance improves over time. Bugs fixed within weeks without need for a hardware fix.
2) App development - any x86 app and OS runs now! very, very cool. If you don't like windows, you can develop linux or BeOS apps, and it will run. Out of the box, this thing is running everything you have and will come to have. And, the possiblities inidicate being able to run different OS apps at the same time (Java and Win running simultaneously was mentioned - I'm sure more is possible).
3) Power Management - geez, could you ask for a better performance. Sure, your disk drive, cd-rom may eat up energy... but saving power is saving power - why eat up more than you need? Also, with appliances - that will probably use flash cards. Since its software-based - they can continue to improve it.
4) These two are just the first in the family... can't wait to see what the next ones will be like. If they are releasing 700 mHz in production now, they must have close to 1 gHz in development for release by years end. Seems to me, they stated they were conservative in the initial product debut, and that they are capable of much more in terms of power, performance, and optimization.
5) Intel and Sun doesn't have much to worry about on the desktop and server side - but, they'll face a good fight from Transmeta on the portable side... this is going to get interesting.
Why? For today a new microchip was released! How can I possibly contain myself?
If it weren't for Linus, this processor wouldn't even have garnered 1/50th the interest that it has now.
Again, some quotes from the datasheets for the processors:

- The strongARM only requires about 400 milliwatts vs. the crusoe's 1 watt.
- The crusoe has compatibility with existing software (not just x86) via the code morphing whereas the strongARM is a platform unto itself.
- The crusoe might have a faster clock cycle, but are the extra megahertz used up by the CodeMorphing?
Whatever the verdict, when coupled by emergent display technologies (OLED and SSD), it looks like the future of ultra compacts is all bright and shiny right now.I'm also wondering what the overclocking potential of such a low heat dissipating CPU must be :-)!

Jumping to Conclusions.
Some highlights from the technology whitepaper on the Transmeta website. It should answer some of the FAQ's raised here so far. (My comments/observations in italics).
Code Morphing software will "typically reside in standard Flash ROMs on the motherboard". This implies it could be in RAM, and potentially dynamically reconfigurable or switchable, on a suitable designed motherboard. (Elsewhere the paper implies that this ROM software is or can be copied to RAM at boot up for faster execution.)
The VLIW engine has "two integer units, an [FPU], a memory (load/store) unit, and a branch unit". These can operate in parallel.
All VLIW code, both translated x86 (or whatever) code and Code Morphing code, live in a separate memory space invisible to x86 code. The size of this memory space can be set at boot time or the OS can make the size adjustable. This last implies that the OS can somehow see this memory, so it's either not totally invisible to x86 code or the OS has some VLIW code hooks.
"The Code Morphing software includes in its arsenal a wide choice of execution modes for x86 code, ranging from interpretation [...] through translation using simple-minded code generation, all the way to highly optimized code [...] A sophisticated set of heuristics helps choose among these execution modes based on dynamic feedback information gathered during actual execution of the code." This sounds a lot like Sun's "HotSpot" technology for Java VMs. Either way it sounds cool..
"the translator adds code whose sole purpose is to collect information such as block execution frequencies, or branch history."
There's hardware support to help the code morphing, ie support for exceptions, speculation, optimization of memory and for self-modifying code. All x86 registers are shadowed, there's a working and a shadow copy. As blocks of x86 code get translated, that page's entry in the Crusoe MMU (for the translation cache) is marked as "translated" so that it doesn't get translated again. A write (by x86 code, indicating self-modifying code) into that block causes that bit to be cleared.
The Crusoe processor voltage and clock (at least on the 5400) are accessible to the Code Morphing software, which can adjust them on the fly to optimize power/performance for the running app.

From the Transmeta FAQ:
20. What is Mobile Linux?
Transmeta is creating a Linux distribution to support its OEM customers called Mobile Linux. Mobile Linux is designed for systems without hard disks, such as Mobile Internet devices (for example, Web pads, clients). The principal enhancements for Mobile Linux will be in power management and in the reduction of the memory footprint.
Back to top
21. Is Transmeta getting into the Linux distribution business like RedHat?
No. Transmeta does not intend to support end users.
The purpose for creating a Mobile Linux for OEM customers is to provide a total solution including the Crusoe processor, the Code Morphing software, all the required driver support for our motherboard platform and the Mobile Linux operating system. This will provide our OEM customers with the best combination of features and time to market for the emerging Internet device marketplace.
Back to top
22. Does Transmeta intend to release Mobile Linux to the open source community?
Yes.
I have this potentially stupid question. Would it be possible to write assembly code in crusoe's vliw instuction set. Or to write a compiler that produces "crusoe-instruction-based" code?
Couldn't this make the processor even faster as there would be no need for software code morphing?
Or doesn't the code morhing slow things down at all?
Ok, I will stop smoking crack... honestly
What happens when the code-morpher-software crashes ?? Anybody has a clue about this ...
Processor panic? Code morpher protection fault?

Looks like they beefed up their web backend in the last few minutes, the slashdot effect that was going on has disapeared for me. Slashdot seems to be more
According to Transmeta's FAQ, they're planning on releasing the source code for Mobile Linux.
2. where are the q3-benchmarks ? they're mentioned in the introduction of crusoebenchmarkreport_1-18-00.pdf but i can't find them anywhere. looks like crusoe is lousy in floating point.
This is going to be a really great product, and several great products are going to come from this. I can already see how the web-pads can make my daily at-work life much easier.
However a couple of points that the formal talk (which I watched live in its entirety over the webcast) which I felt were missing:
1. Focus on x86 translation. Obviously the technology could be taken much further, but the whole talk focused on just x86 code. What about translating other code?
2. The differences between the two chips weren't made clear (the website helps). From the talk you were left wondering, 'Why would I want anything less than the 700mhz chip?'.
3. No mention whatsoever of desktop implementation. They made it perfectly clear that they were focusing on mobile products, but what do you call those machines Linus and Taylor were playing Quake on? Light laptops are great, but I still want a desktop machine with ultimate power!
4. Mobile Linux? Isn't Linux meant to be free? There was no mention of how or when we get to find out about the changes/improvements in this new version.
5. How do they propose these webpads get and stay connected all day? Are they preaching wireless lan technology?
Anyway, I'm really looking forward to getting my grubbly little mits on one of these machines. And now we all know why IBM chose this time to announce its adoption of Linux.
insignificant sig
The implication that they consider the low level stuff part of this their business, and, as you suggest, the "cash cow." It is part of their "competitive advantage" to be able to do that which nobody else can, which is to customize the processors in this way.
ON THE OTHER HAND. Not giving out the underlying instruction set means that they never have to apologize if they change the instruction set. They claimed that there were different instruction sets for the 3120 and 5400 models; if that be the case, it would be no surprise at all if later models are different again. If people are interactive via "middleware" instruction sets, then all Transmeta need do is to make sure that the microcode continues to support the "middleware," whether that be IA-32 or JVM.
Vision for the Future.
There is a really cool thing that this offers... Wouldn't it be a neat idea if Linus were to create what we might call Linus' Favorite Instruction Set, with all the features that he wishes there were to make Linux as fast and robust as possible?
Alternatively, the Lisp Machine people might find it a slick idea if Transmeta provided microcode to provide a Lisp-oriented instruction set that (notably) provides a really tightly microcoded set of garbage collector instructions. That would let them both benefit from MHz enhancements as well as from generational enhancements, perhaps simultaneously having some IA-32 emulation going on so that they have a virtual machine alongside providing PC compatibility services...
If you're not part of the solution, you're part of the precipitate.
I noticed that their chips' names (TM3120, TM5400) are somewhat similar to Texas Instruments' naming scheme for DSP's:
;-) I don't know where the TMS came from here, I'm pretty new to TI. Maybe "TI Microprocessor Solutions" or some such.
TMS320C6000 (TMS320C6X or 'C6000 for short)
TMS320C5000
etc.
Not too much alike - theirs starts with TM for TransMeta, obviously, but is much shorter; ours start with TMS - but might be enough to confuse somebody (or get somebody's lawyers' panties in a bunch).
All the usual disclaimers apply, IAAISL (I Am An Inactive Status Lawyer), etc.

So does the VLIW substrate have an sort of intrinsic endianness? If it is little-endian in nature like the x86 that it's so good at emulating, then this could result in a noticable performance hit when emulating a big-endian CPU like the 68k or PPC.

Interesting stuff.
Judging by the speed of Slashdot today, Slashdot has been crushed under the Transmeta Effect.
I doubt, therefore I may be.
The thing that disturbs me is that we have benefitted as consumers from the competition between intel, AMD and others. If what transmeta has done in fact turns out to be a significantly better design approach, they may never see any real competition.
Intel has to publish it's instruction sets to get people to write software for the CPUs. Nothing legally prevents other companies from designing CPUs that offer the same instructions. Thats why AMD and others are in business.
During the announcement, transmeta indicated that it has been granted (or was it sought?) numerous PATENTS, not just copyrights, on concepts related to software defined instruction sets. If they are upheld, would that not keep any other company from designing a hardware / software combination that does a similar thing from competing with them, even if the hardware and software were designed from scratch?
If someone reverse engineers a crusoe cpu and builds one that is hardware compatible, and transmeta refuses to sell the software component without the accompanying cpu, isn't that like the old apple machines who never licensed the bios so there could never be a (legal) market for clones?
Yes, this post is another thinly veiled rant against intellectual property rights law, as it impedes growth and competition in many industries.
"Monopolies cannot come into existence without the assistance of government." - Ayn Rand
I don't want the government to break up monopolies when they become large and vicous, I want it to stop creating them.
Contrary to the summary above, the ZDNet article states:
"Crusoe will not be targeted at personal organizers such as the Palm, or at cell phones, executives said."
Its written in it, so it is its ultimate instruction set. Anything on a lower level of abstraction is a compromise, and a compiler can deal better with that compromise than an emulator.
With closed source this is definetely a very efficient way to be able to scale processing power. For open source it is mostly irrelevant to start with if the architecture changes. Given the amount of man years wich go into making a processor porting the kernel is trivial.
Funny how this processor was touted as the ultimate Linux processor and it turns out to be the ultimate (low power-) Windows processor...
This was after they proposed a new set of benchmarks, because the old ones aren't any good. :)
It's really nothing to be excited about, a slow CPU that doesn't consume much power. A niche product at best.

Transmeta Breaks the Silence, Unveils Smart Processor to Revolutionize Mobile Internet Computing
For Immediate Release
Contact:
Carla Cook
Ketchum Thomas Public Relations
650 596-2281
carla@thomaspr.com
SANTA CLARA, Calif. (January 19, 2000) - Transmeta Corporation today ended four and a half years of
secrecy with the introduction of CrusoeTM , the world's first family of smart microprocessors. Designed to
create a new category of Mobile Internet Computers, the Crusoe processor family (www.crusoe.com) is based
on a breakthrough software approach that will revolutionize the field of mobile computing. Crusoe delivers on
the market's need for "all day computing" with a PC compatible solution that is unmatched in performance with
low power.
The Mobile Internet Computing Market
The evolving class of Mobile Internet Computers includes a rich set of products that spans from Web pads to
ultra-light (less than four pound) Mobile PCs that share the common need of x86 software compatibility and
long battery life. It represents a significant shift from today's mostly stationary laptops or incompatible
handheld devices to a platform that offers greater mobility and access to the Web from most anywhere at
anytime.
Ultra-light Mobile PCs operating with the Windows operating system and Microsoft Office applications can
take advantage of the Crusoe processor's low power to increase the average user's productivity by operating
on a single battery for up to a full work day.
Crusoe-based Internet devices such as Web pads and mobile clients can take advantage of the Mobile Linux
operating system to create a robust yet economical machine that can handle all the required Internet plug-in
applications. Mobile Linux offers an additional advantage in that it is an operating system that can be stored in
solid state Flash ROM thus removing the need for an expensive hard disk drive.
"Cellular phones became more pervasive when they were made smaller and provided greater battery life," said
Dave Ditzel, Transmeta's CEO. "We believe that Crusoe will bring about a change of similar magnitude in
Mobile Internet Computers."
Commenting on the current state of the mobile market, analyst Martin Reynolds of the market research firm
Dataquest, concurs with the need for a new mobile processor. "When people build mobile computers today,
they use what's basically a desktop processor in a different package," he said. "There's definitely room for a
fresh approach."
"Our customers are telling us that significant battery life improvement is the most requested feature by a
margin of two to one. That's why Crusoe's low power is so important," said Transmeta's Jim Chapman, vice
president of sales and marketing. "The current mobile market needs to evolve from today's heavier (six to ten
pound) laptops to lighter weight, high performance mobile PCs. Crusoe will help propel that change."
Re-thinking the Microprocessor
In a radical departure from traditional microprocessor design, Transmeta made innovative use of software to
implement many functions that had previously been implemented in hardware. This approach gives Crusoe both
the high performance and low power required for today's demanding mobile computing environment.
The key to Crusoe's unique architecture is its Code MorphingTM software. Code Morphing software surrounds
a simple Very Long Instruction Word (VLIW) silicon engine to deliver a fully PC compatible processor. It is
this software that provides the compatibility by "morphing" (i.e. translating x86 instructions) to the underlying
hardware engine.
Crusoe is a smart processor that "learns" about an application while it runs and uses that experience to greatly
extend battery life. Using a new Transmeta invention called LongRunTM power management, Crusoe
continuously adjusts its operating speed and voltage to exactly match the needs of the application workload.
LongRun can make adjustments hundreds of times per second, which can dramatically extend battery life. This
is in contrast to other processors that run at a fixed operating speed on batteries, needlessly wasting battery
life.
LongRun also provides a solution for today's strenuous multimedia applications that typically drain an
ultra-light PC's battery in as little as an hour. With LongRun, it is possible to design a light-weight mobile PC
that plays a DVD movie for three hours or more.
"We rethought the microprocessor from the ground-up," said Ditzel. "Crusoe is the first processor to deliver
all three of the key requirements for Mobile Internet Computing: low power, high performance and full PC
compatibility. Now manufacturers have the ideal solution for true mobility."
The Crusoe Product Family
The Crusoe processor family consists of two solutions, the TM5400 and the TM3120, for the Mobile Internet
Computing market.
The model TM5400 is targeted at ultra-light mobile PCs running Microsoft Windows and NT operating
systems. These PCs will take advantage of the TM5400's high performance (up to 700MHz) and LongRun
power management to create the longest running mobile PCs for office applications, multimedia games and
DVD movies.
The TM3120, operating at up to 400MHz, is designed for economical Web pads and mobile clients. With the
Crusoe processor and the Mobile Linux operating system, users can expect a complete Internet experience,
including access to the full range of plug-in applications. Transmeta provides Mobile Linux assistance to
OEMs looking to accelerate their time to market with new mobile Internet devices.
Pricing and Availability
The TM3120, available immediately, is economically priced for Linux-based Web pads and devices selling for
$500 to $999. The 333MHz version sells for $65 while the 400MHz version sells for $89.
The TM5400, sampling now, will be offered in a range of performance levels from 500MHz to 700MHz to meet
the needs of ultra-light mobile PCs selling for between $1200 and $2500. Transmeta expects that
Crusoe-based systems with these attractive price points will be available in the marketplace by mid 2000. The
500MHz version will list for $119, while the 700MHz version will list for $329.

finally! a laptop that doesn't burn my knees off! yay!
Emulating CISC based hardware is vastly easier than achieving acceptable performance emulating RISC based hardware. With CISC based hardware, each instruction does a lot, and might take several clock ticks to execute. The Transmeta emulator can come along and translate the instruction into equivalent Crusoe instructions, and achieve roughly comparable performance. This is why PC emulators can be run on PowerPC hardware, and why the MacOS's 68k CISC emulator was so successful for running old applications on PowerPC based Macintosh's.
RISC emulation is vastly different. Each instruction doesn't do a whole lot, but runs extremely fast. So, basically, to emulate a RISC processor, you have to translate each instruction into one or more Curose instructions that don't benefit from RISC hardware's pipelining and other efficiencies. You're going to end up with a vastly slower PC.
Also, this chip will not be able to emulate multimedia enhancements like 3DNow or the G4's velocity engine as fast as the native version. These chips are optimized to run the special instructions in a highly efficient and parallel manner. The multimedia enhancements in hardware basically utilize almost all the hardware technology that Transmeta has in their chip, and tehy don't have the overhead of translating intructions before being able to execute them. The Transmeta chip's software layer simply won't do as good a job as dedicated vector processing units.
Please remember that 700mhz doesn't mean shit. You need to know how fast the processor actually runs x86 software, not how fast it runs the Crusoe transcoding software. Its the same with all emulators. Would you rush out and buy a Macintosh with a hypothetical G4 chip running at 1GHZ that only emulated x86 software? Of course not! You'd know that a x86 native processor running at 700mhz would probably be faster.
Sig goes here
With all the hype surrounding this, I still think that Transmeta has a lot to do in terms of asserting itself.
:)
I mean sure it was a great idea to hire Linus and make a big secret about everything, but because of that people are going to be VERY sceptic about everything they are doing from now on, and somehow I don't see how they can benefit from it.
Sure the PR stunt is achieved, but once people get down to the hard facts, Transmeta still has a lot to prove, and has NOT sold a single product that we know of in 5 years ! This is a big risk for a company, whichever size it is. All the best to you Transmeta, we'll be watching
Intel has been severely dragging its feet getting SA-2 ready...
Read up on active powersupplies.
So, it's kinda like Digital's FX!32, but translating to their VLIW instead of alpha, and implemented at a much lower level, combined with the sort of power management that you have in a palmpilot?
Is this a technical violation of the GPL?
You're forgetting IAONAL (I Am OBVIOUSLY Not A Lawyer). Linus can license Linux to anyone under any terms he wants, because he holds the copyright.
Impressive Performance Claims
Babaian's claims for the E2k would sesm unbelievable, if not for the credibility of the Elbrus team. In a 0.18-micron six-layer-metal process, he says, the E2k will run at 1.2 GHz and deliver 135 SPECint95 and 350 SPECfp95, yet it will require only 35 W of power and 126 mm^ of silicon (with 256K of on-chip L2 cache). We protect that in a similar process Merced will operate at 800 MHz and deliver 45 SPECint95 and 70 SPECfp95 in 300 mm^ of silicon at 60 W. Merced, however, is ahead of the E2k in development by at least a year. Even more amazing, Babaian claims the E2k processor will be x86 binary compatible and, after a few tweaks, IA-64 (Merced) compatible as well. To achieve this feat, Elbrus will rely on binary compilation assisted by emulation hooks in the processor, a strategy which, not coincidentally, is similar to the tack that Transmeta is apparently taking (see MPR 12/7/98, p. 9). The similarity might arise from the fact that Transmeta cofounder and CEO Dave Ditzel spent several years at Sun working with Elbrus. Babaian believes, however, that his company's binary-compilation technology is more advanced than any other on the planet.
Im sure extreme zealotry and fanatism dont get much worse than this. So, just because Linus is a Transmeta employee we must jump in excitment and kneel in front of the 2 processors. Gee, there must be a lot of hardware designers reading Slashdot; otherwise, Id not understand that nobodys asking about the REAL systems using these microprocessors. At least a motherboard to be able to roll your own machine. But, since its Linus, I think everyone forgot that little detail. Do you guys remember the Media processors? What about the Transputer? No? Well, that figures. Unless there are machines or at the very least motherboards using the chip, it will never be any better than a museum feature. So who are the manufacturers designing the machines and/or mobos? How long will it take for them to show up in stores? How is this different to the Microsoft hype? So, fellas, cool down and sit. Stop all the cheering. This is not the Second Coming and Linus is not a Messiah. Gee, I thought Steve Jobs was the only guy with a reality-distortion field. I know better now. Moderators: If you want to moderate something, why dont you moderate this? Let there be flames!
Can you imagine the performance increase you'd see if you compiled directly into the native Crusoe instruction set, so it could bypass all that code-morphing (emulation) software?
If you want a REAL paradigm shift, make the Linux compilation process transparent to the user and easy enough for Joe Sixpack's grandma to do. It would work like this: Joe Sixpack's grandma downloads a source code file, and the first time she double-clicks the file the OS automatically compiles it for her, then launches the newly-created binary. In the future when she double-clicks the same file, the OS is smart enough to just run the binary.
She would never have to worry about which version of a binary to download (Linux x86, LinuxPPC, Linux Alpha, Linux Crusoe, etc.). Just get the source code and she's golden.
If recompiling was this easy, then who cares that you'd have to recompile when a new Crusoe comes out. If she moves her source code file onto a machine a newer Crusoe, or a totally different processor for that matter, the first time she tries to run the app (assuming an appropriate compiler is installed on that machine), the recompiling would be taken care of.
And obviously neither are you, because Linus only owns the copyright on what he wrote. He didn't write the OS himself. Other people have copyright on their contributions, and licensing of their own. Just how do you think he would retroactively be able to change *someone else's* licence?
Open Source. Closed Minds. We are Slashdot.
AA Lithium batteries will probably work with these chips. They can handle 1 watt burst loads without heating up and browning out. I am assuming these chips were developed for AA battery powered devices, it is too big a market to ignore. I Wonder if the price of lithium batteries will come down?
A closed chip, running an object-code only, proprietary compiler, translating to an undocumented machine language, all to emulate an X86 chip, oh, and "other architectures", if the high priests at Transmeta decide to grace us with interpreters for them.
Of course, once Transmeta writes an interpreter for a certain instruction set, there is no guarantee that they will support that instruction set for future chips.
How nice of them to "protect" us from having to recompile by simply forcing us to use the obsolete X86 instruction set.
I'm so underwhelmed.
We've fought too long and hard to get away from proprietary, closed-source hardware and software to go back now.
This might have been "cool" 10 years ago.
I Think I'll pass. Thanks for trying.
All that hype for nothing.
So, since we could get updates to the CPU off the web as they said in the presentation, what's stopping people from creating a program that turns my Crusoe chip into junk a.k.a. a Crusoe virus.
How do I fix a chip that doesn't have any instructions in it?
Jesus people, quit bitching about something that you don't know anything about. Transmeta won't open the instruction set for the Crusoe because they want to have the ability to change it from CPU to CPU. That way they don't end up building up tons of obsolete crap (like Intel from the 8086 days) They can start each processor with a fresh design, and the only software that needs to be ported is the Code Morpher thing. It's not an anti-OSS thing like you people are making it out to be. Hell, if they were doing that, Linus probably wouldn't be working for them.
It's for the same reason that they don't give the information needed for random people to write morphers - they would end up with things like "SPARC morpher, only for the XXYYY version of the Crusoe." It makes sense for them to only let people write software for the other CPUs and have it run emulated (especially since there seems to be such a small loss in speed) They want the freedom to design each new chip as they see fit without building up tons of backwards-compatibility crap, the lack of which is exactly what allows the Crusoe to run so cool and use a such a little amount of power (as well as make the chip cost so little to make)
Sorry if this post doesn't make sense or rambles, I haven't slept in 2 days. But I'm sure you can get the main idea.

Two things that have been hyped by secrecy. I was really looking forward to both The Phantom Menace and whatever Transmeta was working on. So far, I am impressed. Now where can I get one?
JET Program: see Japan, meet intere
I took a compiler class in college, but only remember enough to be curioius, and am hoping someone who knows what they're talking about could answer.
Compilers do a lot of compile-time reasoning to try to predict what happens at run time, optimizing both register use and instuction order. However, this is not done solely based on the ISA- there are significant assumptions about how the processor actually executes instructions.
Crusoe, in optimizing execution, has the benefit of *knowing* what's happening at run time, as opposed to a normal compiler that has to guess about it at compile time. Also, because the x86 ISA is implemented in software, they could do all sorts of crazy stuff beyond instruction reordering. For example, if the compiler guessed wrong about what set of values to keep in the registers, the code morphing software might be able map hardware registers in Crusoe to values that were being sent to memory in the original code.
Which is all well and good. But given that there now are two astonishingly different execution models for x86 code, what are compiler writers supposed to do? Is the amount of information that a run-time optimizer has so much better than a compile-time optimizer that the compiler guys should just give up? Or do the constraints on the complexity of run-time algorithms (they've got to be *fast*) mean that compiler optimization is still worthwhile? If so, how will compiler authors cope with the potentially vast differences in optimizing for Intel vs Crusoe? Will we be seeing a Crusoe-opimization flag in gcc?
More questions than answers...
The point is, if you compile C code for the VLIW, it will likely run slower than the same code compiled for the x86 architecture and then run through the code morphing software.
The reason for this is simple: read their tech whitepaper. In it, they talk about memory protecting for out-of-order loads and stores.
If you have C code like
b=a[d]; *c=5; h=a[d];
then this code will run slower unless you can do the out-of-order check and run-time recompilation: if you compile it yourself for the 128-bit VLIW, you lose: your C compiler is NOT ALLOWED to perform the same optimizations since you could get incorrect results.
The really new innovation by Transmeta is those small bits of simple hardware that allow them to trap violations of optimization assumptions, not the 128-bit VLIW part: the latter could have been done by anyone at any time.
Well, stopping the rant now and beginning to wonder when I can get my hands on one

Anyone have any ideas when we can start seeing machines running these?

It's like Where's Waldo, except more geeky!
It seems to me that Transmeta has choosen exactly the right mix of design , speed , power consumption. And marketing it at exactly the right time. Handheld market is hughe. Waiting for Nokia:s next product series :)
holy shit! you mean IBM has a real business strategy and a strategic vision of the future?
The athlon technically does emulation of the x86 instruction set, allbeit 1/3 of the transisters are dedicated to it. Really no modern app uses it anymore, at least they use very few x86 instructions. They all use mmx, sse, 3dnow and other non named sets that have been added, mmx, sse, 3dnow are all simple instructions, even though as a set there not really a "reduced instruction set" but I like the way processors are going, all simpler faster instruction and alot of them to keep programming relatively easy
We now know that Mr. I-Decide-What-Gets-In-The Kernel (Mr. Torvalds) is a partisan player on one particular low-power hardware platform. Will this come to mean that kernel development for other low-power platforms (the StrongARM comes to mind...) will suffer? I certainly can't see Transmeta being overly enthusiastic about paying Linus for further optimisation-for-portability changes that benefit their competitors.
Maybe it's a moot point, though, as NetBSD is a more finished OS for the StrongARM anyway, and for embedded work doesn't drag along the GPL baggage.
Gee, this is almost exactly the same thing I had to do 30 years ago - load the microcode into the old IBM 360/30. Big difference is that this is the size of a postage stamp rather than the size of a VW bus. (Also I don't think you'll need rotary switches to suck the code in off of 8 inch floppies) On the other hand, it might be a good platform to build a system that runs JAVA bytecode. I can see why they're targeting x86 stuff, but hopefully they'll eventually do something interesting..
As much as im amased over the processor im thinking of the possibility of upgrading hardware with software. We know what happens then dont we (the CIH virus). Virus writers will definately make atleast one virus that will change the instruction set or maybe even infect the processor itself (is possible, but probably hard) as virus writers love these kind of stuff. If not them a skilled hacker och cracker (reverse enginerer) will figure it out and then its not long until a virus is developed for it. The only thing lowering the risk is exactly what they are doing, a different instruction set for every processor. /Bhunji
To wit: the Crusoe chip is x86 compatible. Goody. Don't run windows, couldn't care less about clock-speed obsessed, power hungry Intel/AMD chip designs. But code-morphing makes it sound as if I could throw Solaris on the little bastard. Or OS X. Or BeOS. Hell, I might even boot to a Guru Message. :)
I mean: that what it sounds like. Is that possible? Is it reasonable to expect? If so, I need new shorts.
If not, ho hum, another Intel knockoff. Nice power consumption, and some over-time optimization, but nothing spectacular. Which would really start to stunt my inner geek child.

According to their FAQ, they are planning to release the source, but they are not getting into the distribution business.
Not to slight their work as the chip sounds wonderful, but the concept of dynamicly changeable microcode isnt new... DEC did it 20 years ago with the pdp8 ( i belive ) ... AMD and TI had their bit slice components at least as long ago if not longer... but its still great chip work with the silicon.... i wonder if portable linux is gpl?

would be able to turn Lacey Chabert, Natalie Portman, Jessica Alba, and Britney Spears TO STONE!!
Why couldn't they do this???
nope. from what i gather this just goes to sleep and back up again at full speed with noops/hlt for power saving. variable speed asynchronous machines cant be handled by linux due to its bogomips setting..basically it loops when booting up and stores the cpu rating which it uses for timing. Linux cant handle asynchronous machine architectures yet (and indeed no solution was presented other than checking the do_hardware_timer() in the last kernmel discussion on the subject - check the mailing list - and this solutions was rejected since it was too costly in terms of cpu time). BTW, i'd love to know whether this chip can run the java VM at full CPU speed - i'd love to crunch my servlets on a non dedicated java vm emulating processor which apache runs x86 instructions as usual.
OSS software does not suffer that much from architectures not being backwards compatible. Designing a processor is a couple of magnitudes more work than writing a compiler for that architecture... and if you have the source and a compiler there is no need for backward compatibility.
If thats truly their only concern why not make the specs available with a license mandating use of the information be constrained to developing OSS?
No it cant be done at compile time... but whats to stop the compiler from generating code wich uses the same mechanism to change the code during run time?
Anything wich can be done with x86+emulator can be done with code generated by a native compiler, but not vice versa.
The way I understand it, is Transmeta got stats from the general "mobile computing" public,
:)
which stated people were not happy with the length
of time batteries last in there "computing appliances". (Duh!) Why not, instead of investing 5+ years and tons of money etc... solving the problem for only the "mobile computing" market, solve the problem for every battery user in existance by making a better battery?

from reading some of the white paper on the chips it sounded to me like it would be difficult for them to use other instructions besides x86 for one thing the system bus, PCI/memory are geared for x86, would it be possible to run PPC instructions when your core logic set is geared for x86? is this something the code morphing software would handle, or would you have to have an OEM intergrate different core logic sets (like sawtooth mobo equivilant) into the device and then be able to run PPC (or other) instruction sets?

I live in the Las Vegas area also and know EXACTLY what this AC means about high ambient temps. In my room I have 2 computers, a large stereo and a 27" TV. With all of these on and in full power they have been known to raise the temp of my room as much as 12F. During the summer here this can be quite annoying since the A/C doesn't always cool the house down to comfortable levels during peak temp hours (about 2:00pm until 5:30pm). Writing code in my room can be quite a perspiring experience. I think that a desktop grade Crusoe will be very nice, and it will help me keep my elec bill down at the same time.

'nuff said.
firstly, two points to think about:
;-).
1. the chip is not only more efficient but also colder, hence you save also the fan (power, noise, moving parts).
2. there is such a thing as enough power. we have passed the stage where you wait for applications - now they wait for you. this will power application machines. I seriously doubt it will power games, graphics, etc' machines.
now for the neat part ("paradigm shift", I guess):
computers have been stuck in two ways till now - one is that the smallest unit is still the pc, and the other is that the possibility of backwards incompatability has kept us stuck with x86-intel-microsoft, er, technology
what we get now is there is another layer - a "transformation layer" between the hardware and the software, allowing improvement in the hardware without losing compatability and also running code from different architectures together. this is a step forward, and a paradigm that have definite advantages that should allow it to survive and compete, despite being slower and (probably) not doing risc well.
the second neat thing (which actually refers to my first "being-stuck" point) - this could possibly realize the niche of smaller-than-pc computers. until now it just didn't work well enough, can we now expect a small notebook/diary/phone/organizer/whatever to be the "common pc" (let's say for every member of the family/business) with fewer, more powerful computers being the centers of local networks and/or doing the real heavy work (and games). well - just think of the possibilities...
this is a new step, all you are saying is that it is possible to not use it well - but just think of what can happen if it is!
the AC $0.02, hope it was worth your time...

ARM can pretty much do all this anyway, though not 128bit (does it matter). The bonus I suppose is the Ix86 compatability.

Sigh.
What I'm talking about is GPL'ing (no - not Open Sourcing) the CPU. That really would've kicked Intel in the pants, the same way that Microsoft is being kicked by Linux.
But no, in the end the mighty Transmeta has the usual closed solution.
I'm amazed that someone of Linus' supposed image could even be associated with this. But I guess with everyone else making huge bucks with Linux, he decided to sell out for the quick buck.
Perhaps someone will hire RMS, and really kick butt in the chip industry.
You can run quake 3 in software mode under mesa as you say at about 3 frames per second.
But you're missing something here. This is transmeta we're talking about and that was Dave Taylor, the SAME dave taylor that once leaked a document onto usenet ranting about the inferiority of hardware graphics accelerators and that what he really wanted was a generic parallel processing chip that could do arbitary transforms.
(anyone got the link to that usenet posting on deja that dave taylor tried to cancel?)
GEE, a lot like the crusoe chip can do?
Isn't it feasible that they have put hooks into their code morphing software that optimises specially for 3d transforms and mesa/opengl?
Especially in the linux version? Where they have all the source code to linux and mesa?
Hmm, what fancy optimisations could those clever brains come up with.
Maybe those transmeta laptops WON'T need 3d accelerator ships?
And it would completely defeat the purpose of a low power laptop to put a big,hot,power sucking 3d chip in it. So I'm assuming that demo of quake3 they showed WAS running in software mode.
Someone prove me wrong?
Transmeta doesn't really have to participate in the clock speed race (BTW, if you factor price into it, Intel isn't even close right now)... A 700MHz P3 and a 700MHz TM5400 CPU do not perform the same. In a repetitive section of code (which is most of the code being executed in real world applications), the P3 just executes the code over and over re-doing the instruction translation, the scheduling, and all those things. The TM5400 "learns" what the code is doing and optimizes it down to the point where it executes that code at the same speed when stepped down to 400MHz as the P3 700 does running at full speed and full power consumption.
The example they give is a DVD player, by the time the first video frame has loaded the entire DVD-decoding process has been translated, stored in a translation cache (so it is never translated again), and optimized. If it continued running at 700MHz it would be performing like a 1GHz P3, but instead it steps down intelligently. If stepping down would lose frames or slow execution speed, it wouldn't do it... so until code really really needs over 700MHz in real world applications, Intel will not have outpaced Transmeta. Ithink they'll be around for awhile. And I don't expect this to be the only thing they do. They say they're going to be a professional R&D lab, i doubt they're just goin to keep adapting these processors to different things, they'll move on...
These facts eliminate a few of the bad things you pointed out... like what is the point of integrating 3D if all of the 3D instructions are cached and optimized? There wouldn't be much of a speed improvement if any....
Esperandi
I'm figuring that could become vital in all of this.
I don't want to make a big deal out of it (I said a "technical" violation) but it is not an open source question. It is a question of putting no restrictions on redistibution.
even if it has been done already. That sounds like something a troll would say but it is true, several companies tried this before. I think Crusoe will become popular because it has Linus working on it (free publicity) and it is compatible with current software. Of course mobile users will be all over this but it also has some applications in thin clients and terminals and probably POS terminals. The power consumption and low cost would work to save companies oodle of dollars, not to mention the chips are software upgradable so their useful lifetime is probably 50-75% longer than a regular processor. Does anyone think they might release a code translator for IA-64?
I'm a loner Dottie, a Rebel.
The LCD screens are one of the largest power suckers on palmtops (no moving parts, so no HD). That's why I get 30hours battery life from my greyscale Psion series 5 and those palmtops with backlit colour screens (HP) get 2 hours.

It seems to me that DEC (now Compaq) already has the claim on "code morphing". FX!32 Did the exact same thing for the Alpha line of processors. FX!32 would translate on the fly and save the resulting translation. The result was that the more you used the program, the more code got translated and native code is used. The only thing Transmeta did is to integrate it into the processor.
Based on this, it seems that Transmeta's only real advance is on the power consumption front. This is probably the x86 compatible processor with the lowest power consumption.
I wonder how long it will take DEC (Comapq) to sue for patent infringement.
It should be interesting...
All of this transmeta hype and the end result is yet another intel clone, and a slow one and that. Sure it uses low power... but screens and drives us a lot of power on a notebook, so, no matter how good the guts of it are, it's just another Intel clone. Not impressed.
This is my sig.
C'mon.. two thousand plus NDA's and this is all we get. Talk about the hype and rumor not even coming close to living up to the truth. I can't imagine a more disappointing announcement. Low power? I'll take PowerPC.. C'mon C'mon I know that the Crusoe will blow it away in terms of wattages, but isn't the PowerPC cool enough? Ok, given the fact that it's so cool, it could easily scale into faster speed ranges, but every chip on the market is claiming that they can scale into the multi-gigahertz range. What's new? What's exciting? This sounds like another StrongARM! Everyone that is excited is just so since they don't want to appear to detract from their lord 'n savior, Linus... fair enough... but call it what it is..

- Transmeta patents software-morphing and they are revolutionary geniuses
- Company XYZ cracks down on trademark use in domains and is demonized by the "community"
- Linus cracks down on the use of "Linux" in domains he doesn't "approve" and he's a God
- Company XYZ produces a closed source OS that gains 95% market share and they are considered the devil by the "community"
- Transmeta produces a closed source emulation software and they are the holy grail
How ironic indeed.
This would be an instruction set chosen to be particularly efficiently translatable into the Crusoe native instructions, but would remain constant as the processor changed.
Why can they do this when others can't? Because they can have x86 compatibility at the same time, and cheaply. The system could simultaneously run both formats, just by having multiple translators.
And they could do other things, in particular they could join with AMD and implement its as yet unrevealed 64-bit instruction set.
Let's see:

- Demos of systems running Linux
Methinks DeCSS fits very nicely into the product lines we'll be seeing... Has Linus offered any observations on the knowledge-is-illegal DVD suits anywhwere?Expanding a vast wasteland since 1996.
Oh please. You're not one of the few negative posters around slashdot, but you're certainly among the many negative posters that got moderated up - not because your comment was interesting, but you included the "I'm might get moderated down for this..." disclaimer.
I'm wondering if I watched the same presentation as the rest of the posters here... Deitzel and co. effectively skirted the performance/Mhz question, which says to me that they don't have much to brag about in the performance area, otherwise- They would've bragged about performance/Mhz.
I'm sorry to be rude, but duh. That's how marketing works. You emphasize on the fine points of your product, and you skim over the weak points. Even a moron would not try to shift that focus in their own product release.
I could've sworn I was watching an Microsoft/Apple/Intel love-in/press-conference at times. A quote of note: "Crusoe will be a low power internet platform for the future". What the fsck does that mean? There was lots of 'marchitecure', but little in the way of hard performance numbers.
I sure as hell don't konw what's a "Microsoft/Apple/Intel love-in/press-conference", but if you're referring to the catchy marketing phrases, you might want to remind yourself that you ARE listening to a product release.
Transmeta is a privately-funded company. It's not a university research laboratory. They aren't presenting a research paper. They are a company, and they are trying to make money to make a return on their investment.
Also, their product is targetted at OEMs and computer manufacterers, which is why the technical details are in the press pack, and not the webcast.
Looks like Transmeta's smartest move was to hire Linus, 'cause the whole of Slashdot is believing the (and feeding) the hype without knowing all the facts.
I agree. Those moderators that feed the heretic-wannabes really should stop. Sorry if I sound a bit harsh, but I really can't stand these "I have some pissed-off opinion to be moderated up" posts escaping my score 2 threshold anymore.
powerARM makes a fast low power consumption chip
Transmeta makes a fast low power consumption chip + they have enough good compiler people to write a state-of-the-art fast JITs for it.
A figure the ARM people should get into compilers. In fact, all those hardware people should get into compilers. It is a wonderfull way to get over the backward compatibility problem

peterrenshaw ~ Another Scrappy Startup
I've had a look through the site, but I can't see any mention of how well the Crusoe chips would work in parallel.
Given the low cost and power consumption, they'd seem to be a logical choice for making cheap parallel machines.
Does anyone know if they're able to run (closely) in parallel? (ie. sharing system memory and buses) ?
Either :
- they are actualy dumb and totaly blinded by their wish of being x86 compatible
or : (maybe more likely)
- their are not saying anything to not divert the attension from the x86-compatible hype.
In which case their marketers are just as evil/more as any other.

So, with all this heat/power consumption reduction in the Crusoe chip, does this mean we can overclock it more easily? What kind of speeds can we get if we're willing to get it as hot as, say, a P!!!?
When I moderate, I only use "-1, Overrated". That way, I never get meta-moderated!
People would be up in arms, but he could do it. He has the publicity as the creator of Linux. In many people's eyes that makes anything Linux "his".
I fail to see how this shakes things up much. The top 2 guys Intel and Motorola are very strong in these markets. This seems like a dud.
It has a multimedia processor unit alongside the ALU and FP units. Presumably MMX instructions do retain some speed at least.
1> This sounds much like the 88000 that was supposed to replace the 68000 in the Mac, Amiga, Atari, & SUN stuff before Motorola went RISC. What happened to that project? 2> We need to start working on an OPEN SOURCE instruction set. Like all closed source projects, there have to be some suboptimal aspects to the x86 instruction set. Within the constraints of the Crusoe hardware, we may be able to target GCC towards a GPL instruction set. Of course we'll need an ESR instrution. Plus a GNU instruction that recurses forever. You get the idea. 3> Is there any support for SMP in crusoe? If they run on small amounts of power, and can have their virtual instruction sets optimized for MP, then they'd make nice very small footprint cluster machines. 4> With low power needs, and a small physical size, these would seem to be good chips for building scalable display systems. In other words, think of a foot square display with a crusoe processor, and a really thin edged case. Slide a few edge to edge, and you have a smart large display. (The bigger the display, the larger the CPU horsepower.) 5> Solar powered palmtops. Solar cells on one side, display on the other. When your capacitors get discharged, you turn it over and leave it in the direct sunsight? Kind of a etch-a-sketch for the future. 6> Forget the wind up radio, use those spring loaded generators to power your palmtop. Oktober
Yes, there will be faster chips, but not with the battery. There is also room in rackmountable stuff.
Plus I am looking forward to high-end SMP laptops. Here the power savings is not as important as speed. (Think demos.)
No, Transmeta does have some good opportunities if they can execute well.

I don't want this to sound like flamebait, but if you don't see immediately the possibilities beyond just having a waycool Linux-based PDA, then I hope you're not working in the technology field.
Remember, if the Crusoe can emulate the x86 family, then emulating the PPC, the Alpha and the Motorolas -- or anything else, for that matter -- is just a matter of software.
This has the potential to be the first true multiplatform system. This is what gives it the potential to be both an Intel-killer and a Microsoft killer. The user can run whatever they feel like -- most importantly, x86 compatible apps without having to have an x86.
It's this lack of total portability that's prevented me from completely escaping the evil clutches of Redmond -- I still can't run Poser 4 and Jack Nicklaus 6 on Linux. Wine is a valiant effort, but it's not stable enough for that yet (unless some major breakthrough has been made since the last time I checked in). The Crusoe looks like it's offering me a possible way out.
I'm also stunned by the prices -- a Crusoe-based box is actually within my reach. These guys are serious ... I have to wonder if Paul Allen has any idea the danger he's put his MS holdings into by backing this project.
ikaros, who will almost definitely get one of these systems
You're only as young as the last time you changed your mind -- Timothy Leary
Who does Transmeta think they are going to get to buy these processors? Intel and AMD own the market, so TM is awfully foolish to release something like this and dare to compete with the big boys. TM and Crusoe are doomed.
That's an interesting point. They Could also have Open GL, AltiVec, x86, and MMX all in the Morphing ROM code at the same time couldn't they? If the ROM isn't big enough Couldn't you just add another one? For example could you have a Morph Engine for your sound card instructions, video instructions and x86 instructions communicating with an arbitrary number of TM CPUs? That way adding a chip increases video and sound ability too... Then again I don't know anything about hardware ;-)
it sounds like the chip does the translation one-off into native machine code. So after the initial translation it should presumably run at native speeds.
if the chip's internal logic for optimisation was embedded in a compiler, the optimisation layer would be redundant and you could generate native code that could run un-translated.
Since they've got the technology for instruction morphing, COMPATIBILITY DOESN'T MATTER ANY MORE. They could just write an emulator for the old VLIW instruction set and then go on to change the instruction set any way they please.
Of course I can see that they wouldn't want this burden on day 1 of their release. On the other hand locking people into their VLIW instruction set (or any of the versions thereof) would probably be good for them.
One reason for Transmeta not to encourage writing native code for the Crusoe instruction set is that it very quickly creates the same trap as the current x86 instruction set: Backwords Compatiability. No one wants to buy a computer that cannot run the software that they have now, and this kind of attitude propigates down the line, until we have an instruction set that is being held back by the fact that we're still carrying the capability to use software that noone has been interested in for 10 years. If Cruose starts having native code programs written for it, than the next time they want to make a "next big thing" jump, they have the ball and chain of carrying all the old instructions with them. No one wants to rewrite their compilers and programs to work on a radically new instruction set, but maybe a radically new instruction set is what will be needed to face whatever computing challanges come up in the next 2/5/10/n years. Someone mentioned earlier the "vulerability" that Intel was facing, because they want to move away from the somewhat bloated by thoroughly entrenched x86 instruction set. x86 has so much momentum that Intel is going to have some very big growing pains once they try and move away from it. Leaving the code morphing in place as an "insulator" between programs and the instruction set permits them to tinker with the chip itself as much as they need, while keeping the support of users and developers, who will be happy to avoid a complete system overhall and rewrite every 2 years. Plus, if the Code Morphing is as fast and quality as the hype, than the ding in performance will be minor, and barely perceptable to most users.
The biggest problem with the StrongARM, the draggonbalz, or any other crappy portable processor, is that they are *NOT* x86 compatible. Making an x86 compatible processor means that millions of screaming Linux weenies will have something to play with. Oktober
Having Linus playing games. I felt sorry for the dude. Looking like some kind of trained monkey. I can go to chinatown and watch a chicken play a piano too. Next time their demo would be cooler if it had a barnyard animal playing quake!
Now it seems to me that the Crusoe processors that are coming first are mobile just because the intial ideas of Transmeta lend themselves well to that application. Has anyone else read the whitepaper and seeing what I think I'm seeing? It looks like they've just taken the back end instruction unit of a more traditional CPU to start. But rather then add microcode and transistor based software to control getting software instructions to it, they've moved those functions in normal software. This allows the actual CPU's to be cheaper, smaller, and simpler (hence the lower power requirements, in addition to their clever management scheme). But is it just me, or does this also provide a fascinating layer of abstraction? Couldn't the code morphing software just as easily be programmed to dispatch instructions to multiple VLIW cores? Not to mention all the advantages of being able to write more complicated software that can make better choices about how to optimize and keep the core processor running. Very interesting idea I think - lots of possiblities. It seems like it's essentially turning the x86 instruction set into an API, so bigger and badder advances on the silicon side of things can be taken advantage of without having to go crazy optimizing existing applications. Abstraction is one of the most powerful tools we have, and this is a fascinating use of it. Of course, they don't mention much about the extra RAM that translation cache and code morphing software is going to require - I wonder what type of cost this abstraction comes at.
Ok I read the whitepaper now. The read/write reordering would be as usefull to compiler generated code as emulator generator code.
Instrumenting the code seems to serve two purposes, to determin wich code to most aggresively optimize and for tracing branches. (to determine wether to do speculative execution of the most common or even both branch targets)
The first purpose would not be much of an issue with a native compiler, everything would get fully translated. The second would still be an option for compiler generated code.
Apart from changing the optimisation level of code and changing it depending on branch probabilities they dont seem to mention any other instances where the code would be changed during run time...
Mobile Linux ought to be good for all of us.
Even if Intel is able to respond to Transmeta by improving StrongARM, Mobile Linux will run on it too.
Linux has needed a consumer-level platform to grow, to correspond with success in the server and workstation area. Microsoft and Intel have not been able to come out with a good mobile platform (one without a hard disk) since the HP Omnibook. And 3Com needs some competition to its pokey CPUs.
The mobile, handheld computer applications are likely to grow along with cellphones and increased wireless bandwidth. It will be good to have real web pages instead of just a few lines of text and no graphics. And we will be able to run our favorite Linux programs too, vi or emacs.
as i read through various sources, i could not help thinking "yeah, it is low power and translates code, but P3's have been translating code in hardware which must be faster".
What IS the Power of Crusoe? Why is it so fast?
/. made everything clear. here it is:
1) Crusoe is so fast (almost equal P3) because the code morphing is done in software. software is slower per se, but it is a lot easier to use lots of memory for state caching, can be tuned easier, etc - all the reasons you would not want to have your average application program etched into silicone.
2) the true power of Crusoe is that actual silicone development is completely independent of previous iterations. if the next-best-thing-after-VLIW gets invented, they can put it into silicone in no time flat, while all other processor developers can only watch from a distance. WOW. WOW. WOW.
of course, there is also small die size (read: cheap!) and low power comsumption. but these advantages pale in comparison to 2, above.
I don't see any reason you couldn't write code morphing software for MAJC (or IA-64 or whatever), although it might be tricky because of the exception ordering issues mentioned in Transmeta's white paper.
If Transmeta can keep the competitiveness of the
chip up from a speed/computer-power standpoint, then vendors of RISC instruction sets will do a cost analysis of whether its cheaper to design their own processors or to design software to program Transmeta's. Licensing terms and Transmeta's ability to drive volumes would also be pivotal. They do give up some control, true, but this may be preferable to an Intel-only migration, since with Transmeta they can retain their ISA lock-in and binary compatibility.
--LP
Since these chips are smaller, etc.. Would that mean that they will be cheaper than Intel processors of similar speeds? It would kinda make sense in the case of the "web pad" where people might not want to spend more than a few hundred dollars.
Does anyone know the estimated pricing of the processors?
Nobody builds processors that directly run the ix86 instruction set any more. Both Intel and AMD put out processors that execute RISC-like instructions at the core, and then surround it with a lot of machinery to translate the user level instructions into these operations on the fly. There's no reason why Transmeta's approach can't be competitive to that, especially given caching of translated instructions.
What we're seeing is the rebirth of microcode. This approach makes the most sense when executing a tightly coded instruction stream -- CISC instructions, or maybe bytecodes (there might be a performance advantage in doing JIT translation from Java bytecodes to VLIW instructions, but then again the combination of the two JIT translations, from bytecodes to ix86 and from ix86 to VLIW might be nearly as good and cheaper in the long run.
..and the fan in my PowerBook G3/400 doesn't run constantly.. Chances are the next PowerBook will also be fanless...
... they are still emulating the x86 instruction set. Even with all their fancy technology a 700mhz processor will only perform, at best equivalent, to a 500mhz Pentium.
It is important to realize that the current Intel and AMD CPUs do not execute x86 instructions, either. They use hybrid RISC cores with front-end instruction decoders to break down the x86 CISC operations into smaller, RISC-style operations which can be more easily optimized.
So I wouldn't be so quick to dismiss Transmeta's performance claims as impossible simply because they are using emulation. If this was traditional emulation, I would agree with you. But it isn't.
In traditional processor emulation, you write a special program which sits between the host CPU and the "foreign code". This program reads the foreign code, figures out what it is doing, and does it. Essentially, you write a program to act like the foreign CPU. Not very efficient.
Transmeta's "code morphing" techniques, on the other hand, do something a little more intelligent. They start by translation of x86 to native instructions. So you are running native code, with an up-front penalty for translation. Then they apply selective optimizations to tune the translated code to the native design as needed.
Given time, that could result in much higher performance then traditional emulation. You might get very close to "native" performance by optimizing the code that matters in ways that apply to the native CPU.
Or you might not. There is very little hard data available right now, so all anyone can do is speculate. We can't say "Yes", nor can we say "No".

The loader would recompile for the native machine, giving outstanding performance with complete hardware transparency.
I believe at the time there were Amiga, Atari, Macintosh and 386 ports - all binary compatible.
-Anonymous coward
(And How can they call it VLIW when there's no 1-1 mapping between instructions (atoms) and execution units?)
Not sure that is a real term but as I understand it x86 processors don't have the stuff to be fully virtualisable so people have to do really clever hacks like vmware so we can run multiple OS.
Now that the instruction set is in software I wonder if Transmeta can make this a bit simpler to do?
Flexibility Reliablity Funtionality and last Cheap 1 watt power consumption easily means solar power Battery what battery use a flashlight for light. Now that ya got an xtra bay what to do. But other devices would suck the life out of the battery Software for coding, hum that will be tweaked The chips not going for claims to speed but feasible battery life Sounds like this could be the beginning of the practical laptop market. Intel with there newly debut itanium-64 bit and Crusoe 128-bit why pay more for something outdated within months Cant be a hoax with IBM shelling them out before there on sllers shelves. Oh and Paul Allen multi -billionaire dumping money into so fast he forgot he is stilling living with his mom and dad. If Crusoe had not been for laptop Joshua from Via would have had little impact on desktop market but Joshua may gain remarkable share of the desktop market while Crusoe take on laptop. What is intel to do but buy a 51% stake and ride it for all it's worth.
Without open sourcing the morph code Transmeta has created a black box. This processor not only has the potential but was specifically designed to track everything that is going on in the machine and react at a very high level. People flipped their lid when a number was imbedded in the Pentium III. Transmeta has the means to imbed, remove and potentially send anything they wish or are pressured to do.
It is my belief that a major reason for Linux growth in the world is the ability for nations and individuals to not only take the word of the distributor but have the means to verify it themselves.
I hope Transmeta can see this very real obstacle for what it is and opens up the morph software as soon as they possibly can.
I feel Privacy and Freedom are integral parts of the same thing. I look forward to Transmeta changing their cash flow away from needing a proprietary lock on the Morph code. I hope they will see this as code death in the internet space.
The processor won't be a personal processor for me until I can look at the source and compile it myself. Then I know what I have and it is mine. This is the only processor package I've seen that has the potential. I have in Linux my "own" OS and I always wanted my own processor. I don't think I am alone. :)
Yeah Tao has always seemed to me to be very cool. Their homepage is at www.tao.co.uk your post made me check them out again... but horrors of horrors, there is a very recent news item saying they are going to cooperate with Amiga. Dont they realise its a kiss of death?
Of course Taos has been kept back by their expensive restrictive licensing/development model anyway... so it wouldnt matter that much if they went under.
Just goes to show how revolutionary Transmeta really is though.
I'd REALLY like to see THIS on a Beowulf cluster!!! ;-)
Bring the karma-toilet on if you don't think this is funny! Heheheh!
............ no.
every look at some assembly listings?
stuff like:
mov eax, 5
mov ebx, [ecx+0005]
cmp eax, ebx
jz 79835024
All that sorta stuff is just your basic i386 (286?) instructions, 95% of code (at least) is just your basic instructions (no mmx 3dnow or whatever)
Technically, if an AS/400 "CISC heritage" compiler were run on AS/400 RISC hardware, the resulting program could in fact run on a CISC box. You are partially correct in that the MI is continuously enhanced with new OS/400 releases and the changes are only forward compatible. At this time, I think IBM still supports V3R2 compatability for the older CISC boxes on the current RISC hardware...
Have you read the Whitepaper on Crusoe? Nobody seemed to realise the real potential beyond the little guy. 1.It says (well, almost) that if you want to get a 4way parallel processor you only have to do minor adjustments in the translation software. And it still won't overheat(I hope). 2.The scalability is GREAT. You could stack 4FPU units, 2 integer units...etc(8 units per total) and use 256bit VLIWs to send data to it. Minor adjustments in the translation software are needed. 3.You can upgrade your hardware without any kind of change to the apps. Merced watch out:)). Think of an 8 way Crusoe being fed reordered translated instructions. By the software god. 4.This is why we should await a little more from Transmeta in the next year. just a little more...
It's easier shooting someone than beating him to death? Hell, it's easier shooting someone than buying the Times. Su
Yep, the really exciting part of Cruso is that enables a basically virtual CPU upon which you could experiment with better support for High Level Languages concepts, like Logic Programming, Lazy evaluating functional programming, Lisp, etc. Alas, the TM revealed much a dissapointment as this will all be available only to TM. From the user and developer perspective all this is is Yet Another x86 with half the power consumption, which doesn't amount to all that revolutionary once you realise that most of the other factors that consume power are basically unchanged.
always i don't have time read article. IMHO,huge streams are human oriented. so wish the genius considerate "easy to use/programming hardware/CPU". Personally, i think future cpu will be uncomplicated instruction structure. anyways great thanks for "new cpu" to transmeta with their brightness. TOT

See, I've always said it like "may-ta", but in the conference they were clearly saying trans-met-a
how do you guys pronounce it, and are both ways correct? and not just for transmeta, but for meta-anything.
may-ta just sounds so much better to me.
If not, well... it's just another boring x86.
Wouldn't it be funto develop a virtual processor -- one which never existed in hardware -- that was designed to map particularly well onto the current Crusoe CPUs? (It probably would not map badly to future ones.) It'd also be fun to precompile critical sections so that dynamic translation would not be necessary for those portions of the code -- the equivalent of custom microcode.
How about it, Transmeta?
--Brett Glass
How about a slashdot interview with a)Linus, or b) one of the other transmeta guys about crusoe?
Opinionated Law Student Strikes Again!
Can some more intelligent people than myself comment on how these Crusoe processors might or might not be able to handle the Intel and AMD SIMD instructions (ie MMX and 3DNow!). Could this morphing use those, or are they proprietary and need to be licenced? If they're not I guess most apps would take a performance hit from not being able to use them?
1) How much do they cost?
2) When/where can i get one? or possibly two? (mmm... SMP....)
So, wait, i thought Linus didn't want to back any particular distro, but it seems he just wrote one for them? Also, why does a processor company need to have a Linux distribution?
Anyway, if the power consumption is anything like they said, then I can't wait to get one in laptop form. Do they have any OEMs' backing them yet?
Opinionated Law Student Strikes Again!
Transmeta says it uses one watt, but that doesn't mean much for low power consumption. Its an indicator, but its like Microsoft and Mindcraft, its more of a half truth...so...What happens to be the milliamp hour rating on the 400 and 700 mhz processors?
Does the name Pavlov ring a bell?
but check this out: it is less than 400 dollars!! now if it runs linux, if i can install the compilers on it, than it's fabulous! my money is right here, come take it.
Does anyone know if this thing can Morph java bytecodes??

Personally, I think the Transmeta CPU's are potentially the "tip of the iceberg" when it comes to CPU designs.
Remember, Transmeta has only shown x86 instruction set emulation; it could conceivably run another CPU instruction set (e.g., PowerPC G3 or G4). After all, if it takes only a little programming for the TM3210 or TM5400 to run Java almost like "native code"....
The very low power consumption of the Transmeta CPU means the elaborate and expensive CPU cooling needed for the mobile Pentium II/III CPU's are almost eliminated; this also means that battery life can be dramatically increased, which means that the "Internet appliance" shown at the demo today will become reality at a reasonable price.
By the way, the Transmeta TM3210 could form the basis of the "Internet terminal" most everyone forecasts to be popular in the next few years. Because of its lower power consumption, such terminals could be quite small, and could be fitted with USB, IEEE-1394, RJ-11 analog telephone and RJ-45 10/100Base-T Ethernet connectors. In short, it'll be just one flat panel box, with motherboard and a small HD in the box, plus external keyboard and mouse pointer.
It'll be interest to see if TM3210-based machines can compete against the Sony PlayStation2....
Raymond in Mountain View, CA
what about sticking one of these chips on a PCI add-on card for a desktop PC ?
since these CPU's can be reprogrammed to execute virtually any instruction set they can be used as great hardware accelerators.
e.g. start a java application, the computer reprograms the crusoe as a native java processor and you have a java accelerator card!
or when you start a game , you reprogram the chip to do 3d instructions (@700MHz!!!) and there you have a 3d accelerator! .
or make it do encryption!
the possibilties are unlimited!
and when no application is using the card, make it do work for distributed.net

he was quoting a bowdlerized version of the original:
In fact, Ditzel was really building up momentum. I asked him what had happened in early 1998 -- when he was quoted as saying "We had a major change in direction a few months ago, and that has slowed us down a bit." His immediate answer drew applause, and probably the biggest laugh of the morning. "That was just something to throw off reporters.
That's a lie. They found out the original chip couldn't compete with Intel's performance. This is when they decided to go after the mobile market. They're making it sound like they were aiming for the mobile market all along. That's just not true - they changed direction when they couldn't compete.
I really love these chips, but it's much more x86-centric than I expected. Low power is all well and good, but that's not really what I see as the great strength of Crusoe...what about other Instruction Sets?
PPC? Sparc? Alpha? Even more intriguing, what about IA-64?
I know that they repeatedly said they could do this sort of thing, and during the Q&A said that Mac compatibility is theoretically possible, but will any of it happen? TM will have to write a whole set of code-morphing software for each ISA. Have they even done any work on these fronts? To me, THIS is the real potential of the Crusoe family.
That said, this type of thing may require more work than just the code-morphing software. For instance, to achieve Mac compatibility, you would need to do a whole lot more than get PPC compatibility. They would have to comnvince Apple to design a whole motherboard/chipset to work with this processor, which means any possible Mac compatibility would be a LONG way off, even if they did manage to strike a deal with Apple. Is this in Apple's best interests? Certainly. A PowerBook with even more battery life would be wonderful. But will it happen? Somehow I doubt it. I assume the same probably holds true for other platforms as well.
Any thoughts?
Obviously, from the extensive demo'ing Transmeta did today, their method of run-time recode and optimization works. But think of what else a dynamic microcode processor can do! The dominant x86 binaries run fine without recompile. When the dominant arch switches over to PPC/AMD64/IA64/TM256/etc, Transmeta adds a new flashed layer of microcode, and now our three year old 'IA32' Crusoe laptop will run Windows2004 for the SuperAlpha-III.
There is nothing that ticks me off more than buying a $12,000 workstation that will be useless in four years when the manufacturer decides to switch processor arch and no longer offers support.
.sig: Now legally binding!
So what? you still get a speedup from not having silicon implemented branching instruction sets. The software can do a better job and generate no heat in the process as well. Crusoe Assembly makes little sense. It would be like trying to write a book using ones and zeros.
he who has the fastest cart always has the best lie.
Does this mean that Transmeta will be helping the Linux/DVD cause?
sup
I think you've missed the main thing that's wrong with Transmeta: it's the lack of a key vision as to the possibilities of an exponential market explosion based around their product. They're occupying the valley instead of conquering the universe. Let me explain.
... and 10 times the pity because the presence of Linus must have kept the benefits of community development pretty obvious within the company. A missed opportunity, possibly the biggest missed opportunity ever to occur in computing.
What's the single most important lesson that the computing scene has learned in the last few years? Hey, that's an easy one: that the massively parallel development in the Free/Open Software community outpaces that in even the best funded closed commercial teams by a huge factor, easily two orders of magnitude. The productivity is without peer, verging on the ridiculous by traditional measures.
Yet Transmeta is not opening up the development of Code Morphing Software to the community, apparently as a result of an incredibly regressive devotion to the antiquated concept of Intellectual Property and its laughable protection through obscurity or non-disclosure. So, instead of the next few quarters seeing a myriad of ports of CMS to dozens of architectures being attempted (and inevitably quite a few of them succeeding rapidly), we're going to be forever waiting on the closed Transmeta team to deliver. It's going to be the pits. It's going to be annoying. It's going to be slow.
Even worse, open development would be highly likely to optimize the hell out of the x86 version of CMS in very short order, far more rapidly than TM could despite their current great lead. You just can't hold back a thousand highly enthusiastic parallel streams of development, even if there is a substantial attrition rate. In contrast, now it's going to be a straight race between TM and Intel, and in this head-to-head between closed teams, only a fool would discount Intel despite the far greater ease with which Crusoe can be optimized compared to Intel hardware.
This is a terrible waste of a supreme opportunity. Transmeta could lay to waste all competition everywhere with Crusoe if they freed CMS from its appalling harness of proprietary development. Imagine all computing everywhere running on TM hardware, simply because Crusoe executes *all* instruction sets in current use. That's not an impossible vision, but it can't be achieved within a small closed group of developers.
What a pity
[And no, their portability/flexibility argument for not opening CMS and the VLIW architecture does not affect what I've said above, because whereas the porting of CMS for a single ISA to a new VLIW architecture can be performed effectively by their single centralized team, there is no way that this scales to porting dozens of ISAs to it. That can be done effectively only in a distributed manner. (The portability benefits of non-disclosure could have been achieved quite easily through a simple system of TM design guidelines.)]
I'm sad for what might have been.

More for Less, and better batery life. I say portable DVD and MP3 player is the go My old dauphin (386) had underclocking to save battery, and in em days fans and heatsinks were not needed. With .18 tech had 1.3 volt tech and copper, AMD can afford to underclock too, as die size=profitability. The CPU is now less that 10% of the cost of a laptop. But the darn graphics accellator and 13.1 LCD display now become the next concern. My next point is that perhaps one will be able to single step debug code, to expose obscured secrets
So it's a reasonable implementation of an old idea. The interesting question is whether it works well enough that it can make up for the lack of speculative execution in the machine. From the documentation, Crusoe is a classic VLIW machine; the CPU executes one big word worth of instructions at a time, in lockstep. Visit the Transmeta web site for details.
Post details. Heard this rumor before, but no details. Anyone ---
... they are still emulating the x86 instruction set. Even with all their fancy technology a 700mhz processor will only perform, at best equivalent, to a 500mhz Pentium
That was a quote from a Transmeta employee. I do realize that Intel and AMD processors don't execute x86 instructions. However their vector units (MMX or 3DNow) are executed natively. The MMX unit is highly optomized hardware that takes advantage of all the latest hardware techniques. Therefore, even if MMX emulation was easy (I don't think that it is), it would still be slower because it would be emulated in software. You don't see as much of a penalty while emulating x86 instructions because CISC instructions are relatively quick to translate, and both the Athlon and Pentium are also emulating the x86 instruction set.
Sig goes here
Read somewhere PIII has 7ms latency, Athlon more like 23, which is why PIII not dirt yet. IF Athlon can trim this number down - huge improvements in store. Intel has no more rabbits to pull out (bar moving to real copper fab).
Linus was misquoted (I think).. He was talking about his eight-way Pentium Xeon box when he said his system took forever to boot. (Not a Gateway)
They are building The Time Machine with Crusoe
I don't suppose you've ever heard of FX32, Executor, UltraHLE, Nestra, YAE, Generator, sope, pex, or the dozens of other emulators that use this technique.
Transmeta is a chip company. They have come up with a innovative new chip for use in a mobile platform. How that platform will connect to the internet, is up to the companies that implement the chip in their portables.
The internet connection could be something as simple as an ethernet jack that you would plug an ordinary cat-5 cable into, or it could be an Apple-stype airport wireless LAN connection.
Personally, I'm going to use a Ricochet wireless modem.

While I like the idea of trading off a bit of performance from today's way overpowered chips (for general workstation use, anyway) for compatibiliy, I'm not quite sure on what Crusoe provides. Can I run a win32 and linux binary similtaniously without rebooting? Because if I have to reboot, hell, I can do that with my current intel systems. Some comments mentioned performance would be terrible for RISC emulation...what other CIRC processors are out there that are even worth emulating? The only advantage I'm clear on is the power savings, which Intel can easily compete with before Transmeta ever gets off the ground. It's a nice idea, but with Intel having more of a monopoly then the Redmond crew, I don't see what we need to emulate.
The instruction sets are different - and the binary-to-binary translation software would then be different because it has to translate to a different instruction set.
However, as the Compatibility page on the Transmeta web site says:
so they're "binary-compatible" to the extent that they can both run x86 code.
Umm, Linux is a "popular PC operating system", is it not? Given that, the above indicates that Crusoe processors, plural, can run Linux.
For that matter, the Crusoe processor family page says quite explictly of the TM 5400 (that being the chip to which you're referring):
I heard it as an 8-way Pentium Xeon that took forever to boot and was really noisy.
.. do they use?
You know - now we have quite a selection of hardware but still most of the browsers people use (MSIE and NN4) are crap. And others are unknown/don't have momentum/not fully featured. (With a possible exception of Opera on Wintel).
And secondly - what's SO important about WebBrowsers?
The phrase, "To the metal..." doesn't quite have the same meaning after today. As a programmer I have always equated programming to the metal with the ultimate in speed but now there is a whole new spin to consider with this new layer of software around the core. As a big fan of both Linux and Java I feel pretty good about abstraction at this low level. It's like object oriented CPU design when such a thing shouldn't really be possible. The best part is that you get a performance gain. Very cool!
Transmeta. This, of course, should mean some pretty spicy freshness for wearable PCs. I'm not certain, but I think they're currently using a 200 pentium in there; replacing that with a 700 Crusoe should speed it up a good bit and use less power. Might even cost less.
And yes, I just purchased stock in Xybernaut (XYBR).
Question though: does the display system of a Xybernaut system (which beams into your eye) use less power than a regular LCD?
The first part of this is, of course, hardly unique to Transmeta; binary-to-binary translation's been around for ages (dating back at least to the IBM System/38, compilers for which generated a very CISCy pseudo-instruction set that got translated to the native instruction set by code running on the machine; the AS/400's continue to do this, which made it easier for them to switch from the older S/38 and AS/400's with their 360-ish instruction set to the newer AS/400's with an extended PowerPC), and it was also used, I think, by HP to migrate users from the 16-bit stack-machine HP 3000's to the 32-bit PowerPC HP 3000's, and Digital's^H^H^H^H^H^H^H^H^HCompaq's FX!32 translates x86 Win32 programs to Alpha Win32 programs.
A Smalltalk implementation for the 68K, by L. Peter Deutsch (yes, Mr. Ghostscript), translated Smalltalk bytecodes to native 68K instructions, and, of course, Java just-in-time compilers do that as well.
I have the impression that FX!32, at least, would do post-execution optimization of the generated code based on profiling.
What I think is new about Transmeta's stuff is
So if I read this stuff correctly, software upgradable processor. Open-source mobile linux. It should be easy enough to overclock one of these babies with a few lines of code. Then we can create a virus that will enter through this "elusive new internet connection" and fry someone's chip. Gotta love technology!
I heard no mention of SMP. Is the hardware able to handshake with its siblings?
Lots of applications have critical areas tuned for cache and other features. Will these applications be severely impacted running on a morphed processor?
I can't believe the number of people who talk out of their rear-ends when it comes to compiling Crusoe code natively. The "Smart" part of this "Smart" processor is the software! Skip it and your left with a processor that can't do out-of-order execution or any other "Smart" function. To all those people who want a native Linux kernel or apps please read the docs before you comment. Oh yea and you would need two ports one for each model since they differ on the backend!
Im moving to a dual or quad cpu systems soon. Will crusoe do multiple cpus? Its software based right? Soon as AMD comes out with thier quad system Im all over it. -Brook
thanks, somebody had to explain that.
It would be interesting if someone, a reporter or /. hack, were to put together an overview of the various rumors that have floated around since Transmeta started up in '95.
But I've been thinking about some of the other potential Crusoe has. The possibilities are mind-boggling, and I can only hope Transmeta recognizes them and will exploit them soon...
On a side note, I hope Transmeta doesn't go public. Then they'll be beholden to the whims of investors who care only about short-term returns, even if long-term interests suffer. They've already got some serious funding behind them, and they have a good chance to make a killing in the market to recoup the money they've invested. What would they really gain from an IPO?

Ahem, the 'traditional' is still used a lot in most applications. Even as we now have the 'cool' extra instruction sets, the file loading and other basic tasks still have to be done. And in those the MMX,3DNOW,etc don't help at all.
This is by far the lamest announcement that has ever been kept a secret. Coming out with YAIC (yet another intel clone) seems ludicrous. The only advantage they have to claim is reduced power usage! The power that the processor in laptops is consuming is becoming the power consumed by the rest of the system like the screen and hard drive. There doesn't seem to be any interesting work being done at Transmeta. Maybe I'll release a slower Intel processor next week -- I'll call it the P-II.

Now that they "made it" I hope Linus will have a lighter schedule probably and linux (kernel) will resume its normal evolution...
:-)
OK, Linus is our hero, but you know that the best ideas usually don't have the best success. It's usually the worst ideas who have great success like: any Microsoft product, SQL, Intel x86 processors.
I wish Transmeta the best of luck though, I reckon Crusoe could even penetrate the PC market in the end.
Bizar technology?
First of All, I apologise if this point has already been made (which it probably has!). I tried to post this last night but /. wouldn't work (had it /.ed itself - i was attempting to post during the announcement itself)
;-)
I'm just curious about the performance specs. 400 MHz for one of the variants released today and 700 for the other says nothing. They could advertize 20,000Mhz for all I care.
I mean, comparing Athlon and Pentium on MHz is stupid enough and this Crusoe is a completely new (and off-the-nut!) architecture.
Even if the 400MHz refers to the virtual x86 performance and not the "native" Crusoe clock-speed I want to see real benchmarks now (Quake fps, Excel calculations etc.)
I was quite pissed-off when the first few suits on kept emphasising that they were "going for the megahertz" - they deliberately didn't clarify but I suppose they just want a big IPO so extreme hype and FUD is needed
since it is maintaining compatability with x86 instruction sets, it will always follow Intel's lead (and require Intel to continue leading) mainstream chip technology.
Not quite, what they have done is to create a programmable processor. There is nothing that limits theire ability to add new fuctionality. And, unlike Intel or AMD, Transmeta can just release a upgrade to the 'morphing' software, where AMD or Intel would have to roll out a new line of processors.
It will never run as fast as a native x86 chip would (because it must execute extra instructions). Of course, being smaller and independent to the hardware, these chips may be made significantly faster (clock-wise) than mainstream CISC/RISC chips and comparatively match performance. But not yet
The 'morping software' is implememted as "lazy morphing" meaning, "translation-as-you-need-it".
Although this means that the first time you run some partition of the code it will be a bit slower, overall is might actually speed up the overall execution. The reason is that modern processors have lots of instructions that are rarely used but have to be accounted for in the processors' microcode. And the microcode is basically just a huge "case" loop. Ergo: The Crusoe has the potential to actually be *faster* than it's competitors. Remember that they are changing the processors microcode on-the-fly.

How about this? To speculate what Trans-Meta is going to do for server processors! Have a multi-processor VLIW and "morph" it so it appears you only have to compile for one CPU no worries of clustering requirements, it all scales up.
I reckon Crusoe is just a simple (therefore low-power) chip with a nifty JIT'er (in software). So, why invent the chip? Why not just use an existing low-power chip like the ARM/StrongARM?
Looks like Crusoe will be best used as a java platform.
The Transmeta processors seem to be part of a general trend to define increasing amounts of functionality in software, rather than actual physical hardware. Another great example of this is MIT's software defined radio project (http://www.sds.lcs.mit.edu/SpectrumWare/home.html ) which basically attaches a fast DSP to an aerial, allowing a single device to emulate anything from multiple flavours of cellphone (GSM, CDMA, AMPS) to a walky-talky or a radio. Combine Crusoe with a soft radio, and you have an incredibly powerful mobile communicator, that can change its fundamental nature with a software download!
You dont change a processor just like that... even if you have the freedom to change your ISA at will redesigning a processor is a massive undertaking. Not to mention start up costs for a .18u chip.
Designing and implementing a new chip is much more work than creating a new compiler backend and porting the kernel IMO.
Wouldn't this processor be great for Overclocking enthusiasts or is there something obvious that would get in the way of this.
If it runs at 48deg C at 700Mhz then can't we boost up the clock speed a little?
May not be much good for mobile computing, where Transmeta seem to be focusing, and the CPUs won't be available to end-users (nor will the equipment), but isn't the potential there?
To be honest I would like to see something run natively on VLIW instructions, surely that would rock!
I'm old enough to remember when discussions on Slashdot were well informed.
It promotes binary foreward compatibility... wich is fine for buessinuess. But what I personally want to see is source code portability. The amount of optimisation you can do for your architecture is always greater at the source code level. (that doesnt mean you cant still use tricks to do stuff at run time)
Oh BTW others have already said it, but the Crusoe is very much x86 optimized.
As for handheld stuff... if you dont care about x86 compatibility there are processors wich are more efficient. Why would you use Crusoe?
The universe can be anyone's as long as they agree to distribute it under an Open Source license, eh?
Cmon... give me a break. Simply put, it does not pay to tell your competitors all your secrets. Yes Open Source has it's benefits, but when you are running a business, it pays to sacrifice some of this flexibility for increased profit. Just ask Bill.
This is even more of a concern for a company which has done nothing but R & D for five years (i.e. SPEND money).
Best regards,

Exceptions, floating point formats etc are hard to emulate if the underlying hardware doesnt map naturally to them. (x86->Alpha for instance)
Everyone who thinks only mmx and 3d instructions are executed these days...bloody wrong! Take a look at the generated assembler code of a program you created, or install SoftIce and take a look which instructions Windoze pumps thru your hardware...
What exactly do you have in mind here? The problem with GC is not so much efficient instructions, but rather efficient strategy for maintaining the reachability graph.
Hardware support for write barriers might help, but given that write's are rare (10% of instructions), and usually you can do the barrier on traditional hardware with a few instructions, you don't buy much. The difficult part is what comes after a triggered barrier.
There is hardware that snoops the bus to maintain reachability stuff in parallel, but that is essentially independent of the CPU.
Anyone care to speculate how to do hardware GC?
But, this thing runs Linux natively. Now, either this means they've gotten gcc working under it, or it'll need to be ported, and then, things will be able to be recompiled into natively on to a, and let me clear my throught and look intensely at all of you before I say this, 128 bit processor. This means vastly improved accuracy in all calculations, and this is especially important for floating point numbers, such as the ones extensively used by, say every 3d app known to exist (at least by me). Now, I'm just speculating at this point, but this gets me very excited. Has anyone here heard of a wonderful little box called a dreamcast? Guess what, it's got a 128 bit processor in it. Do you know what clock speed it runs at? 200mhz. That's right, it can push out it's massive frame rates running at 'only' 200mhz, admitedly with it's impresive 3d chips as backup. But what do you think it'll take to get one of the two big (or even top four) 3d chip manufacturers to make a card that'll run on this chips platform? Not much, I'd wadger, after a many thousands of crazed linux nuts start crying for them. Then consider that the low end chip that's coming out is running at 400mhz, and is priced about the same as a celeron. Now, I don't mean to get everyone thinking that we'd all be living in some fantasy world with these chips in everything, but I am pointing out that there is some missed potential. Anyone with more techinical knowlage of both 128 bit computing, and the Dreamcast's platform, want to shoot this to crud, or perhaps agree with me?
If you haven't noticed, they have been working non-stop for 4 1/2 years. With no IPO money. At the top, it says they spent a sum of money 'well north' of $100M. When sales pick up their debts, they will be a privately held, debt free fabless R&D company. How many of those do you see around?
You can't legislate goodness. Let each to his own destiny, by will of his freely made choices.
The whole code translation stuff will have to be loaded into the CPU, since loading such important stuff with 128Bit instruction set via external DRAM all the time will be much too slow. The size of internal memory used for this will be chosen in a way that it will not suffice for more than one processor emulation. So this would all have to be swapped out and other stuff swapped in on every context switch between tasks for different processors.
This will be one bear of a context switch.
Of course, if you did not multitask at all, things could work quite nicely.
Unless there were a sizeable market for running different processors quasi-simultaneously, I would not expect TransMeta to come up with a processor with oversized translation program memory.
I'd just like to point out for the people who missed it, not rudely, but just to make you perhaps aware of it, that the software emulation layer called code-morphing works at the acceptable level that it does because the chip was built to support the instructions most used by the software layer, i.e. the direct equivilents of the intel instructions. So while other code morphing layers certainly could be done, they performance hit would be quite a bit more noticable. And that's assuming anyone else can figure out how the whole code morphing software works (I somehow don't think that transmeta is going to open source this particular little jem).
One of the strongest selling point of Transmeta is that their processor is low-power and 80x86 compatible.
Well the compatibility is very important for closed source software but unimportant for open-source type where you can easily recompile, so a StrongArm could be a real competitor here,
not only they are cheaper I think but also more power efficient and already here now. On the other hand ARM CPU and the like often have no Floating-Point Unit which can be a bad point for some application.
I don't see how 'morphed' code can exist only in the CPU, since it's software generated. Help, my brain is exploding!

Can someone explain how this emulation thing works ? I read that the chip can run Apple or Win software. But doesn't Apple software, say, need libraries that are part of the MacOs ? And doesn't the MacOs rely on the Apple architecture, not just the powerpc chip ? It seems to me that you would need more than just a chip with code morphing to run software from several platforms on the same architecture. Am I wrong ? Can someone more knowledgeable than me explain ?
nope. from what i gather this just goes to sleep and back up again at full speed with noops/hlt for power saving. variable speed asynchronous machines cant be handled by linux due to its bogomips setting..
I think you got it wrong. They claim their LongRun Technology actually reduces both clock speed and processor voltage on the fly, rather than taking this on/off approach.

"People ask FAQs all the time". - David Allen
Games and DVD stuff should run well enough. Although I would like to see some game benchmarks too.
The real kicker will be stuff like kernel compiles emacs etc.
Between development games and entertainment I have about covered all my needs for high speed processing. Dont need much speed to read my email or browse... I dont think this thing is suited for handhelds or pads.
I want a Transmeta chip for one reason: With a little help from Transmeta, it will be the IDEAL platform for performing low-level debugging of X86 applications.
Why? Except for debugging hardware interfaces and a very rare device driver (which rely on the actual low-level hardware interface), there is no need to develop X86 software on a "true" X86 chip. All that is needed is something that ACTS like an X86 chip, and when performing low-level debugging on complex software, the ability to examine the internal state of the processor at any given time, and to use a debugger in real-time, are both very important.
What if Transmeta built the guts of a debugger into the Code Morphing software? That would allow the developer to easily set the equivalent of hardware breakpoints without having to go through the high overhead of software interrupt tricks or the expense of in-circuit emulator hardware. Both of which also require all on-chip caching to be disabled, further decreasing the speed of the debugging process.
It is my guess that such a debugger is ALREADY part of the Transmeta Code Morphing software, for I see no other way for them to implement and debug the X86 ISA itself.
Even if the "first pass" Transmeta performance rate is just 10% of an Intel or AMD chip at the same clock rate, under a low-level debugger, that rate would hardly be affected, while the AMD or Intel perfromance would drop by a factor of 100x to 1000x due to the overhead imposed by the debugging environment.
In my book, that puts low-level debugging on a Transmeta chip 10x to 100x faster than on true X86 hardware.
Big deal? Well, what if you want to run some processes (say, those that manipulate hardware) at full speed while you debug one or more other tasks? For true low-level debugging, Intel and AMD caches must be disabled, where the Transmeta caches would not have to be.
I have worked on many real-time systems where the state-of-the-art in low-level debugging environments was terribly inadequate. I have had to resort to full system simulations to get some timing problems resolved, an extreme cost to bear for what is a latent "design flaw" in the processor architecture.
Try debugging a settop box where the MPEG decoder is 85% in hardware and 15% in software. The two have to work together at full speed, and even with good software, the system can't run at all when the cache is disabled. Debugging must be done at full speed. Given that, how does one detect and react to a "suprious" event that could be due to hardware, software, or the combination? The debugger needs not only to be fast, but it must also be "smart" enough to know a lot about its environment, if it is to be of much help.
There are many similar examples, for example in robotics, where real masses, velocities and accellerations must be accounted for when a reaction is being comtemplated, not to mention the delay associated with computing that reaction. Again, fast debugging at a very low-level is extremely helpful.
Transmeta's got it. I need it.

Worse, from an open source point of view, is the fact that they won't be releasing the source to their translation engine. They seem to appease open-source advocates by a) employing Linus Torvalds and b) calling it their 'intellectual property'. Well that's OK then. We can all be held to ransom by a company peddling their closed-source solution to everything. Doesn't that sound just a bit familiar? With Merced the compiler, and hence ultimately the programmer, gets to choose the packaging of instructions. With Crusoe Transmeta does it for you, badly. If you really care about open-source, you should be supporting Merced.
There I am thinking how lame .sigs are getting these days but thats just classic (I really feel for you)
This UID is 7651 digits too high to subjectively infer IQ from.

If the x86 instruction set has as much cruft in it as I've heard some people say, due to keeping backwards compatibility from the 286 while adding new stuff on for each generation since, then writing a nice, new, shiny, cruft-free instruction set for the Crusoe (having learned what's good and what's not from the last x generations of processors) could be A Good Thing (tm).
It might be faster than x86 emulation (with fewer instructions to translate, the instructions in the translation cache might stay there longer with fewer misses or something) and compilers for it could probably be ported in a relatively short space of time if it was clean enough.
Hmmmm....a nice new 64-bit OS running on cheap hardware? Sounds good to me
Why doesn't the gene pool have a life guard?
Seeing as the power consumption is so low, couldn't someone put two or more Crusoe chips in a laptop, increasing the performance, while still having a superior battery life to anything that's currently available? Also, the code morphing software could perhaps be adapted to make all applications run multi-threaded, regardless of how lame your OS is. These boys have really cooked up something special with this chip.
How about Java ByteCode? Instead of a JVM which does ByteCode->x86->Crusoe VLIW, why not go straight to Crusoe VLIW?
Think of it! Athlon got all the translation hardwired, and all optimized specifically for x86+MMX stuff. There's no way a software optimizer could be faster. Really.
:)
But it could be cooler anyway
--exa--
So that's it, eh?
The object of all this hype from slashdotters over the years?
An x86-compatible CPU. Wow, big smegging deal!
So the power consumption (under low-use conditions only, if you do the calculations) is lower, but that's it.
Sorry, folks, but that ain't the Revolution you were all expecting. That's pure evolution, nothing more.
Yes, they *claim* they can do emulation of other CPUs. But they don't offer it yet, and there's no guarantee they will.
Interesting how nobody is bitching about the inherrant closed-source nature of the system too. Interesting...
Wake me up if Transmeta actually come out with something new, not just Yet Another x86 Clone, yeah?
First, in the update, this guy quotes linus as saying his "gateway" takes a while to boot. He said "8 way" as in 8 CPUs. Second, I though the slashdot questions at the conference were dumb: effectivly the question was "Can you run different instruction sets on the virtual machines" but the virtual machine itself was provided by their software. The question was not based on the information they released, but on earlier rumors. They could have gotten a better answer if they asked "what are the potentials for running different virtual cpus simulaneously" Some questions I'd liked to have seen were: 1) You say the software in the cpu is locked right in the beginning of the bios loading, no chance for viruses. but you also say that you will be able to download fixes off the web. Explain that! 2) How long does it take for writing x86 emulation, and why (x86 complexity, clean room stuff?) 3) How would the transmeta CPU running a simpler (designed for lowpower) CPU instruction set, like dragonball, strongarm compare. Question 3 is especially good, as especially with linux, x86 isn't all that. All they seem to have is the low power x86 chip, but that doesn't mean that it's the low power chip.
So, what does transmeta mean for the Oxygen project at MIT? I heard Deterzous' talk at RSA keynote on the handheld cellphone/palm-pilot/pager/etc.etc/ that links up to a stationary system (desktop)--I'd bet that the Crusoe will be the backbone behind Oxygen (I'd be surprised if there isn't some collusion already) and if not the Oxygen system, some decent portable connectivity device.

Well, since no one has made a comment on this as of yet, I guess I will. Transmeta has domeonstrated BeOS running on Curusoe. Considering Stinger (Be's embedded product) is almost nearly BeOS, it should be a chinch to put Stinger on Curusoe. That means two things. A) Be gets a huge boost considering stuff like the Compaq webpad (which uses Stinger) can be made much more powerful, and B) It helps embedded products in general since Be is probably the best suited general purpose OS for embedded products. Speaking of OSes I'm not too particularly impressed with the whole embedded linux thing. In my experience, the good Linux GUIs (ie. Windows maker, E, KDM) need a fast graphics card and lots of RAM to work well. Not to mention all the hardware X needs. Can something like the compaq webpad be made that uses X as the GUI? Even the most basic linux X system needs a few hundred meg and that simply isn't available on a webpad type device that uses flash RAM cards. (Or even microdrives) Not to mention all the cost for RAM. QNX would also be a good platform (better than Be maybe) but the lisencing costs would be a bitch. Another problem is the fact that the users of these embedded products are about half as smart as users of normal computers.(not everyone, just most of them.) Were talking iMac user level here. (not mac users, iMac users) I don't see them being too happy trying to configure all the options in GNOME. So reaching the end of my rant it is time to make some forcasts.
A) Be makes a killing of Curusoe by putting Stinger on every webpad out there.
B) All the Linux heads go out and buy a webpad then install linux on it.
A deep unwavering belief is a sure sign you're missing something...
- When used in conjunction with Transmeta's x86 Code Morphing software, the Crusoe Processor provides x86-compatible software execution without requiring code recompilation.
No Listing for Win3.1.1 or DOS--perhaps because those OS's aren't really out there for most of us anymore. So IMHO -- and I assume you'd agree --Transmeta really needs to clarify this issue better.Systems based on this solution are capable of executing all standard x86-compatible operating systems and applications, including Microsoft Windows 95, Windows 98, Windows NT, and Linux.
...Open Source isn't the only answer -- but it's almost always a better value than the alternatives...
Went to check mac-on-linux out with an OS9 cd last night on my linuxppc box, it complained about the lack of a system folder (the OS9 cd isn't bootable), so I'll check it out this evening with an 8.5 CD. It sounds great! It's a wonder I haven't heard of this before - there was much talk about something called sheepshaver a while back, but haven't heard much about it lately...

Unless Win 3.11 or DOS are not "standard x86-compatible operating systems", the note on the TM3120:
sure seems to imply that the TM3120 can run Windows 3.11 and DOS code.
You assume incorrectly - the people who seem to think that they haven't stated pretty clearly that both chips are completely x86-compatible seem to me to be trying, for some unknown reason, to read something into Transmeta's statements that isn't there, and I don't think it's particularly worth Transmeta's time and energy to worry about people who choose to read "the complete range of x86-based operating systems" or "Fully x86 compatible" in non-obvious ways.
There's more to consider here...
1.What Transmeta is doing isn't truly emulation, at least as it is traditionally known. In, say, a Pentium III, the chip uses hardware to decode x86 into a series of internal RISC-like operations. This decoder hardware is a huge beast, taking up a tremendous percentage of the overall silicon and is responsible for most of the power consumption issues. In Crusoe, however, Transmeta moved most of the decode functions to a low-level software layer. Which, being software, has the *potential* to inhibit performance, though saving power. However, they suddenly don't have this huge hardware decoder to deal with, and so can devote that silicon to extra execution units (integer, FP, etc). Which will help increase performance significantly. Whether this is {enough/not enough/more than enough} to compensate is an interesting question, which I don't really think any of us have enough info to truly answer just yet. Also keep in mind that the decode hardware a la PIII can have a negative effect on the sorts of clock rates you can achieve, so moving it to software may help with that as well. Complex decode hardware also forces a larger branch penalty in case of a branch misprediction.
2. Not only can they devote extra silicon to execution rather than simply decoding, but doing the software translation to native VLIW adds further performance benefits. The first of which is this: it allows Crusoe to perform optimizations on the incoming code which would be impossible with a purely hardware chip.
One of the biggest of these is dead code elimination. x86 compilers commonly save a variable out to memory, then load it back in shortly thereafter - this is because of the very limited number of official, or "architected" x86 registers. The compiler thus ensures that it always has the correct register values. Much of the time, though, the load is unnecessary because the register wasn't modified (the compiler was just being conservative). Transmeta's Code Morphing software can detect these situations and actually remove unneeded loads, something that no purely hardware solution can match. And loads tend to be a big performance inhibitor; due to the long memory latencies, as well as the fact that loads typically start long dependency chains, where subsequent instructions require the load to finish before they can start.
There are several other compiler-like tricks that the Transmeta software can (and does) perform in realtime (and with runtime data that compilers don't possess) that can greatly speed up the performance of code.
3. Also, consider this: traditional x86 chips have had to decode instructions every time they execute. This is a pretty big overhead. Crusoe actually caches intructions in decoded, optimized form in a hardware "translation cache". This means that while yes, you do a software decode once, which could be slower than a hardware decode, you only have to do it that one time, versus every time with hardware decode. Thus the cost of software decode is amortized over many many cycles, and might actually be more efficient than hardware. (think about it: 99.99% of the time you're going to be executing native, optimized VLIW instructions coming from the translation cache. Only the remaining small bit of time do you actually have to decode).
4. There is also something to be said for the fact that this chip is targeted at the mobile arena. It's not meant to be the desktop/server powerhouse. The needs of mobile consumers are different. Mobile uses typically use only a small fraction of the processor's capabilities, so even *if* the Transmeta chip was slightly less strong on benchmark performance vs a PIII, it's overwhelming superiority in power consumption still makes it a big win, since you can't notice the slight performance difference anyway. Probably the most taxing thing you might do with the laptop is play DVDs or something similar, which the benchmarks show Crusoe handles just as well as a PIII - and at a fraction of the power.
Oh, and just as a side note: CISC instructions are most certainly not "relatively quick to translate". One big reason behind Crusoe's existence is that CISC decode/translation is a difficult, long-latency operation, that uses a lot of hardware. Mostly because of the variable-length instructions, which forces the processor to use a largely serial decode process. Which eliminates the primary advantage - parallel processing - of hardware. Said decode hardware could be put to better uses. MMX/3DNow instructions are probably easier to translate, being a newer, cleaner extension to the instruction set. Execution may very well be more difficult than standard x86, but the translation itself shouldn't be that bad.
Intel and AMD will happily (and easily) crush the foolish team at Transmeta. Its only a matter of time.
Look through these. There are several documents that indicate which processors have had updates released. Additionally there links that point to additional information re. what's changed, etc.
From the looks of things, it's a PII, Celeron, PIII feature and not in the PPro.
I said there was no text :-)
it leaves out a bunch of processing units typical of a desktop CPU - eg it is integer math only, no floating point unit. My
suspicion is that Transmeta must be doing something similar to achieve this.
If you saw the presentation yesterday, you would know that nothing was "taken out", per se. The whole point of the Crusoe was to start from scratch, design a simple, elegant, low power, and fast VLIW CPU core, and then implement software that allows the CPU to be x86 compatible. It has floating point (which the StrongARM lacks), but it does not have a lot of things that you find on a "traditional" CPU like x86 and Sparc. All of the branching, out-of-order execution, and similar logic is implemented in the software translation, so that by the time the instructions reach actual silicon, they are already as optimized and in the the optimal order as they can be. Most CPUs have HUGE areas of the silicon devoted to such things, when causes them to draw more power and generate more heat.
Also, another advantage shown in the presentation is their "Long Run" power management system (which I supect came about as a side-effect of the code-morphing). Long Run continuously monitors the running code, and throttles both the speed _and_the_voltage_ of the CPU when the full performance of the CPU is not necessary. The example they showed (while running a DVD) was that by combining both, they were able to use only 25% of the power compared to a PIII. Cool.
If only "common" sense was actually that common...
The Great Idea (tm) that Transmeta had was that by doing the instruction decode in software, they decouple the requirements of legacy instruction sets from the hardware implementation. This allows them to use the latest and greatest in hardware design techniques, and even change the internal instruction set to get more performance. They then just tweak the Code Morphing software to recognize the new internal instructions, as you mentioned.
:-)
The big reason why not to code directly for Transmeta's internal instructions is that you'd have no market share. x86 is around yet almost solely because of the "golden handcuffs" of backwards compatibility.
There's also the fact that if you were to code directly for the VLIW internal instructions, you still need to use the code morpher (that's just the way the chip works), so you probably wouldn't derive any benefit. And even if you could bypass the morpher, then you would be depriving yourself of the optimization techniques the morpher uses to improve performance.
Taking this further, Transmeta *could* release a "static" external instruction set that the Code Morphing software translates into whatever the current native set is. Then we don't need other architectures *at all*. All we need is to use this static external instruction set. We don't even have to worry about being compatible with future releases of Transmeta, since the Code Morphing software takes care of that.
They have...it's called x86
Find it spelled linix, win a prize!
Essentially the difference between the Transmeta and traditional microcode is that the Transmeta uses a "compiler" for the x86 language while trational microcode a la Athlon/Pentium III uses a massive hardware base interpreter.
What you lose on the initial compile, you make up on the execution and since you see all the resulting code, you can optimize it.
What we have is the revolutionary idea of treating x86 instructions as a programming language, then applying compiler techniques to generating microcode out of it.
As mentioned, MMX instructions are probably hard to compile in the same way as vector operations in higher level languages are. But it still can be done.
Also, see pages 8-31 through 8-50 (pages 303-332 in the pdf) of Intel Architecture Software Developers Manual, Volume 3: System Programming. It provides some details about the process of updating the microcode.
Since the PalmOS is the leading handheld os shouldn't transmeta be trying to port Palmos to Transmeta chips? Or are they going after a different market? Or are they trying to replace PalmOS with portable linux? I'm not sure what class of machines they are trying to position their chips for?
>Read somewhere PIII has 7ms latency, Athlon more
>like 23, which is why PIII not dirt yet
this is because the P3 have his L2 cache on chip and the K7 dont...
the P2 neither (that have about the same latency as K7)
when the K7 move the L2 cache to inside the chip, the latency will drop alot...
the new latency will be a little more than the P3 because AMD will want to be able to push the clock higher and too lower latency would stop that...
the L2 cache in the P3 is at full speed, K7 and P2 have it at half speed of the cpu (2/5 to K7 800)
if K7 is still faster now than the P3, his new version will be alot faster

Yup 2048 bytes, updated by WRMSR instruction. look like functions only, and you could recover. Possibly enough to disable/subsitute CPUID if line of thought carries to p3. Or add lots of wait cycles - or prevent software copying in hither to unknown ways.
Ars's resident CPU-meister, Hannibal, has taken an in-depth look
From a superficial reading you can send more than one update to the processor, just 2k at a time.
ya'll remeber good old chuckie cheese's chip? Well the benefactor ifin you don't remeber of this fine chip was Patriot Scientific They just announced the .35 ...seem ta me in synch with Torvald's Crusoe... I almost fell off my chair in the lab today when i saw this stock quote on PTSC today http://quote.yahoo.com/q?s=PTSC&d=v1
Its more the compiler then the programming which is important. People code the same, but if they use the right compilers they optimize for this and this instruction set - which also means, it will run on other chips not using those instruction sets, albeit slower. So this is what we call Software optimization for XXX (eg 3dnow and SSE etc.) so weird disussion you guys are having.
