802.11 is Insecure, How's Bluetooth?
After this story on EE Times, perhaps the tide will shift a bit?
"Cipher attack delivers heavy blow to WLAN security - A new report dashes any remaining illusions that 802.11-based (Wi-Fi) wireless local-area networks are in any way secure"
EE Times Article.
Hmm, the attack scales linearly with number of bits. Bummer. -
Intel and Playing Hardball?And we just finished all this dirty laundry of Microsoft today, too. Intel is worried that you may not have the same quality chipset, since VIA wants to do things their own way, and hasn't waited for Intel's blessing. What it really comes down to is that Via is the big dog, in Taiwan, and has tired of kowtowing to the Santa Clara based company. Intel has licensing arrangements with smaller competitors of Via, in Taiwan, and is probably just trying to extort enough money to level the playing field, as the Via chipset is a few dollars cheaper than the Intel sanctioned sets.
I'd give Via the benefit of the doubt, considering that Intel is still flapping their gums about how good RDRAM is, even after Craig Barrett put Rambus down.
Meanwhile, Rambus failure to overturn on appeal the SDRAM fraud charge is blowing up in their face with a slough of shareholder class action suits. -
This could be really incredibleThe screeens wouldn't necessarily be smaller, but just think of the mind-blowing monitors that could be made with this. Have some of the incandescent traffic lights in your town been replaced by LEDs? Notice how bright they are? Now imagine if you could make a monitor that bright with nanocrystals with supertunable pixels the size of, well, nanocrystals. The resolution and color gradients are mindboggling. Think 32-bit color is neat? Wait 'til you see 1024-bit color on a monitor that uses half the power of your current one. (I'm just making those numbers up, but it's very likely the actual properties could be that revolutionary.)
Please note, though, that this has nothing to do with making faster Si-based MOSFETs (i.e. smaller transistors). If you're interested in that, look here, here (great story), or here to see just a handful of the ideas people have. With all of these things in development, don't expect anything to overtake Si as the dominant technology for a long, long time (~10 years, maybe even).

For embedded systems
A couple of notes:
1) This is old news. You can find a much better story from yesterday over at the EETimes.
2) This is for embedded systems and is not really relevent for PC based systems.
3) This isn't even taped out yet... matter of fact they are not even planning to have the design done for another 18 months... it is vapour until you can actually buy it and that isn't slated until sometime in 2003.
4) This might give Transmeta a serious run for its money if it is ever produced, because they are both in the same space... Of course, TMTA being still around in 2003 is a bit on the presumptious side.
5) Oh never mind, why do I even bother... -
The processor is power efficient, not just fast.
It seems that the speed was not actually their primary aim. They are doing the same as Transmeta... Read the eetimes article for full data. From the article: "We're a company that will do products in the sub-15-W range, delivering multigigahertz performance."
-
Not so new...
It looks like they are just reviving old technology and have mastered the challenges of the technology's downside, clock-data racing. Check out the EETimes article. Jecker

Don't hold your breath...
Rather than license its technologies to semiconductor vendors that would wind up as competitors in the marketplace, Nixon said Intrinsity will focus on getting its initial processor design finished over the next 18 months. Going from the test chip to a full-blown embedded processor will consume the energies of the small company.
1) This is just a prototype.2) They seem aimed at the embedded market. I don't think that you will likely see "meaninful" benchmarks.
This quote is from the eetimes article.
-
Highlights...Here's what makes this announcment interesting to me:
The company's test chips are fast. In an embedded market where the speediest MPUs push 500 MHz, Intrinsity's bare-bones test chip operates at 2.2 GHz in a 0.18-micron process with aluminum interconnects.
No copper interconnects. No
.13-micron process. These are things that I (as a non-chip engineer) can understand. Is this going to improve my life? Only time will tell. But I for one like technology for the sake of technology.Quotes taken from the eetimes article.

This is nothing new
The eetimes article clarifies. They are designing chips using dynamic logic which has the disadvantage of eating up significantly more power. It is actually fairly common to use dynamic logic in chips, just not on a wide scale where power is more important than transistor density or speed.
x86 chips are not simple, and creating a dynamic logic design is not likely. The company seems to have very good background in automatied design tools, but chips on the scale of x86 CPUs are not created in automated tools, they are created by hand and optimized (like assembly coding to the software guys)
"Intrinsity's bare-bones test chip operates at 2.2 GHz..." This is not that impressive on a bare bones chip. They haven't even created an ALU capable of that speed. Nevermind a full CPU. This company also doesn't have any fabs, so they will be at the disadvantage Cyrix and AMD were at in their youth.
Overall, they aren't likely to be making x86 CPUs any time soon. PDAs and laptops can't handle the power draw, so I'm not sure where that leaves them. Maybe they should team with Transmeta to solve their power problems. :-) -
Clock speed, shmlock speed.If you read the EE Times article on the same subject (a much better article IMNSHO), you'll see that the aim of this company is to produce high-speed chips with low power consumption. They want twice the speed for only half again as much power.
The company has not yet announced which architecture their chips will use; most likely RISC, and the aforementioned EE Times article speculates that they will use MIPS rather than PowerPC because of lower licensing fees.
This design will not be finished for another 18 months. By that time, Intel and AMD will certainly have passed the 2.2 GHz mark. But still, the embedded systems market should be a little excited over this one.

Re:Er, no you can't.
This isn't a renderfarm node, it'd be a workstation. That's the thing you do your modelling work on.
Yeah. And you never run test renders on a workstation. Ever. No, you send everything to PRMan at once to make the finished render.RAM might need addressing, but then again if you make a specialized modelling suite (or adapt one), you should be able to work within the given constraints. (Remember, you can stream geometry and textures as you're rendering; keeping everything in RAM isn't necessary.)
32 MB RAM is _nothing_ for 3D graphics workstation use. One may be able to create a small low-poly model of some sort as well as fit the 3d program in RAM, but if you have ever worked with 3D projects of some size you'd know how easy a model suddenly becomes large in size, 40 MB or more is not unusual. And that's only the wireframe, textures have to be stored in main RAM or video RAM while you preview the shaded/textured model and when it's rendering.
That's not to say the PS2 (or at least the emotion engine) has no potential, Sony was (or is) working on a 3D/graphics visualizer (not a workstation, but a machine for previewing 3D graphics in real-time, full-resolution) based on the PS2 CPUs, called GSCube (link). -

Re:It's quite simple actually
Unisys modifed the NT code? arf arf arf!
Explain to me just what is so unbelievable about that? The windows source code CAN be licensed in case you weren't aware. They only do it for selected partners who are in bed with them and can pony up the cash. How the hell do you think Citrix created WinFrame in the first place!? THEY LICENSED THE CODE.
On top of that, it is painfully obvious that you have never even STUDIED OS programming. Why don't you go read up on my pack of lies, hm?
If I hadn't already posted I'd mod you down as a troll.

New toys for real good boys.DVD-RAM/RW/etc's? Naw. How much are the blanks? Heh. But CDR's aren't the end all be all, this seems clear. But sony and phillips may have rested on their patents too long. Intel has AMD, Sony and Phillips may have TDK. I love underdogs. Must be all those sports movies I grew up with.
www.cdrinfo.com/cebit2001/tdk-1.shtml Write 2GB CDR's are 36x and the SAME price per meg? The hell you say? Well if ya don't buy the sketchy details and pictures of cdrinfo, maybe A more properly formated press clipin from them might help
:). And just to be thorough, one from EE Times. -
Re:Remember 2.88MB floppies?Everyone keeps comparing this drive to the 2.88MB drives. Perhaps the correct analogy would be to compare our current 700 MB CDRs to the once popular 720 KB floppies. If you'll recall, 720 KB floppies were eventually supplanted by the hugely popular 1.44 MB floppies, which edged out their predecessors despite "only" doubling capacity. Hmmm.
And as others have pointed out, the DD-CD format has a useful niche already. They'd be great for VCDs, Terapin recordings, and DiVX:-) Furthermore, Sony's double-wide disks would be an ideal carrier for the Chinese DVD-patent-busting Super VCD format.

UltraWide Band RadioThey have to be using some sort of spread spectrum stuff as well because it would be very easy to listen in on and jam otherwise.
This would not be good for military operations.
I think that there was a discussion on this sort of technology a while back. Searching EETimes gives these nuggets though:
All of which may shed some light on the tech issues. The articles are well worth looking into. -

It says nothing about captioning at all.The article doesn't even mention closed-captioning. From the article:
"There is about a half a MHz of unused bandwidth in the letterbox, and about a half a MHz in the vestigial sidebands, and we make use of them both to encode the high-definition information," said Nickel.
It looks like the digital signals are being encoded in regions which are otherwise unused (taking advantage of improved signal-processing technology) and the captions are safe.To analog-TV viewers, the extra information will appear to be encoded within the black bands at the top and bottom of the screen -- the so-called letterbox. Viewers will be able to tell when there is information in the letterbox because it will be gray instead of black.

Re:Windows!
What about Firewire?
Microsoft balked at a fee of 25 cents per device!? Even the originally-proposed $1 ssems reasonable. Somebody needs a fact-checker.Now this might have been a really great thing. Even Intel and Microsoft were behind it big time, until they got the word from Apple about the high licensing fees. This prompted Intel to drop support and pay out big bucks for their own R&D, and for MS to just drop out entirely. Yet again, another good idea down the arrogance shooter.

Fujitsu producing 128KB Ferroelectric RAMAccording to this article in EETimes and this press release by Fujitsu, they have been producing their version ("FRAM") in volume since late 1999, and should be churning out 128KB parts even as we speak.
The cool part is that it works by wiggling atoms around in the crystal structure:
external electric field shifts Zr/Ti atoms in crystal to move away from electric neutrality

All too obviousAfter wasting my time reading many redundant posts it is obvious that there is certain type of humor that is particular to those in technical realms.
Reading these posts reminds me a lot of the comments for the Immortal Works of EE Times. The same jokes seem to made over and over with the punchlines being all too obvious. It is entertaining for only the first couple of times and then is quickly tiring. If the jokes are thus so obvious, I'm not sure how any will ever make it to the patent office. Oh yeah, the only thing obvious to the patent office is the nose on their face (maybe).
But to be on topic, my patent:
Efficiency algorithm to eliminate time wasting reading material.To more effectively be able to scan large quantities of ramblings on news groups filters are necessary to reduce the amount of unnecessary reading material. These filters are incomplete and extremely unmanageable to handle all possible configuration options. This algorithm greatly simplifies the process by striking all material unless it contains keywords in an inclusion list. This eliminates the extra dross on topics that are not cared about by the user. It then does a follow-up filter to eliminate all information that is redundant with the knowledge base of the user. This is done by striking all material containing the keywords in the inclusion list. As these union of these two filters is the universe, the process is further simplified by simply sending the entire material to
/dev/null. -

FCC rules on 2.4 Ghz
There's an EETimes article about it here. To sum up:
It allows frequency-hopping signals in the 2.4-GHz band to operate at 1, 3 or 5 MHz, with at least 15 non-overlapping channels spread out over a total span of 75 MHz. The average time of occupancy on any frequency shall not be greater than 0.4 seconds, within a 30-second period. The maximum output power is 125 mW at 5 MHz, vs. the 200 mW the HomeRF group had requested.
This mostly concerns the battle between HomeRF and 802.11, but does give some good info.

Infinite memory
The assumption "the more volume, the more possible positions of particles in the computer" leading to the eventual conclusion of limits on storage capacity has already been invalidated by modern science.
Apparently, infinite information can be stored in a single atom -- no joke. Check out this this EETimes article -- link courtesy of ArsTechnica.
Summary: Philip Bucksbaum from the University of Michigan has stored and retrieved eight bits of information from the quantum-phase of a single cesium atom. Theoretically, there is no limit on capacity. -

a bit on the history of fast PPC chips
For those of you that have fogotten, IBM demonstrated a PowerPC chip running at 1 Ghz way back in 1998 (the chip ran at 1 GHz when cooled to 25 degrees Celcius, at room temperature it ran just at just under 500 MHz). Check out CNET's take on the event: IBM joins the 1,000-MHz club.
The 1 Ghz PowerPC IBM demonstrated way back in 1998 was partially hand tooled. This chip broke many of the processes IBM uses to automate production of the PowerPC. Check outwhat the EE Times said about the chip at the time: IBM's 1-GHz processor taxes current EDA tools.
More recently, TechWeb states some of IBM's plans for the PowerPC: IBM Preps SOI-Based PowerPCs.
To see what is available today, and what is coming in the short term future, look at IBM's product page for the PowerPC at: http://www.chips.ibm.com/products/powerp c/.
IBM intends to have out 700MHz PowerPCs for its RS/6000 line by early next year for its RS/6000 line. It would make very little sense for Apple to not start shoving these into new Macs when they become available.
IBM has had very little trouble scaling the PPC up as it needs to for its line of servers. I really wonder why Motorola seems to be having so much trouble in the MHz race.
OTOH, I remember 3rd party benchmarks that showed a Motorola PPC at 350 MHz smoking an Intel x86 at 500 MHz at Photoshop. And this was back in the day when x86 had MMX and PPC had no Alti-vec. FYI, the MMX instructions allowed the Intel box (running NT) to perform one or two tests slightly faster than the Apple box running Mac OS. Given this type of history, I can see Motorola being arrogant enough to think it doesn't need to keep up the MHz. But its time for Motorola to wake up and smell the coffee.
On a related note, there is a rumor that Palm is going to drop the 68k Motorola series in favor of the StrongARM series mostly because of the MHz.
Motorola better get some MHz action in a hurry. Despite an overall faster chip, eventually a double/triple clock speed advantage will catch up. I doubt a 1GHz T-Bird does much slower than a
.5 GHz PPC, especially given Apple's slower bus. -

Re:No Detailed Specs
Yep, Toshiba came up with this. Apparently it uses the SRAM to prevent the screen from needing to be refreshed when the picture is static. (Think of the difference between SRAM, which does not to be refreshed, and your standard stick of DRAM, which does) Check out the eetimes article he re. The problem I see with this is that SRAM can get mighty expensive in large quantities....I don't see them making even an 8" screen with this technique.

This is only the beginningThe Napster trial, the 2600 trial -- these are only the beginning of the debates to determine who "owns" a piece of work. The DMCA gives the large content aggregators a whole new arsenal to choose from when attacking things they determine to be a threat.
The next round of this debate? Digital Television! While the FCC is telling us that we'll be enjoying this wonderful new technology by 2006 - don't count on it. The MPAA and others are fighting like mad to control the delivery, and playback of digital content that will become HDTV (or DTV). You think they are going to transmit a digital signal and let you receive and record a perfect copy on to box or hard disk? Ha! Not likely...
The Digital Transmission Content Protection Method (DTCP) currently being debated will morph into some new standard controlled by the MPAA and others to control what you can see, and how you can see it. Check out some of these links:

SDRAM not going away anytime soon
SDRAM and DDR-SDRAM aren't going away anytime soon despite whatever patents Rambus claims to own. Rambus have stated that the licence fees for RDRAM technology will be lower than for SDRAM/DDR-SDRAM. However, SDRAM and DDR-SDRAM will still be much cheaper for quite some time to come because the manufacturing cost of RDRAM will always be higher than for comparable SDRAM. This is the main reason why RIMMs are so much more expensive than DIMMs - not because of the licensing costs. See this EETimes story for more information.
