AMD Targets Web Pad & PDA Processor Market

According to this press release and this article from The Register , AMD has leveraged the technology portfolio of recently acquired Alchemy Semiconductor to introduce an ultra-low-power processor designed for sub-PC applications. The chip is based on the Alchemy Au1 core and features, among other things, an integrated LCD controller and a pair of Secure Digital controllers.

      That's a good point, esp. since ARM has the "thumb" 16-bit instructions. It's been my experience lately though (in embedded industrial controllers), that the systems I deal with have a surplus of RAM and flash memory. This is mostly because the older lower density RAM and flash chips are either discontinued or more expensive than slightly-less-old and higher density chips. For consumer products, where people will pack as many applications and data as they can into the available space it still is an issue.

    They're competing with low end laptops for market and components and always suffering in comparison to desktops. Add in the ruggedness that's required (how many times will it slide off the couch or get dropped as someone tries to pick it up one-handed from the coffee table?) and range of uses they'll be put to and it's a tough product to build at an attractive price point.

    Then there's the OS & UI. Folks want the same as they've got on their home PC which mostly means Wintel or MacOS (Linux isn't going to be a popular choice for the consumer market, /.-readers excepted.) Both of these OS's really rely heavily on keyboards and while there have been any number of work-arounds (how many iterations of PenWindows?) they remain clunky without. On-screen "Soft-keyboards" are one option but not one that's ever generated much enthusiasm.

    One clever solution has been to use the Webpad as a remote terminal. This solves much of the software and storage issues as long as one has decent wireless bandwidth. However it does require the "base" PC be on & dedicating resources to the client.

    Windows is not particularly good serving two masters though MS does have some new technology that they've been showing around. However after so many failed attempts in this area vendors are justifiably nervous about committing real resources to it until someone else proves it out.

    Apple has only recently re-introduced partial remote terminal capability into their MacOS line (it was present in Next Step but lost in the transition to Quartz/Display-PDF). There is speculation (isn't there always with Apple?) they're going to offer some combination of local/remote interfaces as part of their "Digital Hub" strategy with a webpad running an embedded-PPC-based MacOS X-lite.

    Linux - well as noted most of the market is biased towards Wintel then Mac. While something with inherently limited functionality like a webpad (not that Linux is inherently limited, just that this wouldn't require a full-blown Linux-for-the-desktop universal solution) and the low cost of Linux would make it attractive the lack of full & easy support for all file formats & plug-is a problem. There are work-arounds but frankly they're not attractive ones from a sales & support perspective.

    Finally, remember that lots of the companies most likely to try out a webpad product are the exact same ones that got burnt on network appliances. In today's deadly market nobody is particularly enthused to chance losing money on another dead end like those, especially for a market & product so similar. Webpads *might* take off but not many want to risk their not, particularly for the low per unit profit most see in them.

    My guess? Aside from a few rebranded models we won't see any from the big names except possibly IBM & Apple. IBM has a good history of migrating technology like this to/from their vertical markets so they've little wasted R&D or manufacturing costs. Apple likes to be a trailblazer plus their customers are open to an all-Apple terminal/server solution. Thus Apple can keep the margin low on the webpad & recoup it on the server. Others? Perhaps some Tiawanese & other manufacturers attempting to build their own brands.

It seems to me that a Pentium (even a basic Pentium, perhaps even missing some instructions) would give them more of an edge. I, at least, would be much happier if I could use the same compilers for my handheld as I can on for desktop. With ARM and MIPS, I'm restricted to gcc and a few others for which someone happens to have gone through the enormous trouble of writing a new backend. Is it really so hard to make a small, power-saving Pentium-compatible chip?

      Is it really so hard to make a small, power-saving Pentium-compatible chip?

      Yes. This is the problem Transmeta tried to address. There are a few embedded x86 processors out there but most of them aren't all that low power. The first "Pentium Compatible" one that springs to mind is the National Semiconductor "Geode". There are also 486 compatible embedded microcontrollers like the AMD SC410/520, and the ZFMicro MachZ.The real problem is that CISC doesn't really lend its self to low power consumtion - too many transistors.

      well yes it is because the Pentium ISA is supposed to be obsolete.

      no one in their right mind would have predicted Intel or AMD would keep it going this long.
      (they want to kill it witness IA64)

      MIPS was actually designed for high performace useing a combination of compiler design and Hardware design it was a academic project and they got it right.

      ARM was designed to be simple take up as little space as possible for manufacturing and implementation (only 2 engineers did the work to start with) as a by product it means that now with moores law you have a product that burns very little power

      there are snags MIPS is more complicated than ARM but once you are over 100 MHz it pays dividends the amount of effort that Digital had to go through to do the StrongARM showed this and again with the StrongARM2 (Intel calls it the Xscale or PX250)

      the StrongARM design team did not really like the idea of working for Intel so they went off and created Alchemy and got a 500Mhz part with not much trouble they also stuck on 2 10/100Net ports USB client and Host I2C and serial a pretty nice chip but funding took a hit and they went looking for investors AMD saw the money that Intel was making of StrongARM and thought that little Alchemy was a winner.

      once AMD was on board they put a LCD contoller dumped 1 of the 2 network interfaces and bingo you have a better StrongARM than Xscale.

      in terms of tools

      what do you have on x86 ?
      gcc intel and lcc (plus globs of half baked assemblers)

      or ARM has: gcc, ARMCC, Greenhills and acorn

      compared to MIPS : gcc algor sgi (plus lots of academic compilers)

      oh and MS has .NET JIT's for ARM x86 IA64 and MIPS 32 Plus MIPS64

      java has about the same but with sparc and some hardware implementations

      regards

      p.s. did I mention that MIPS is really the ONLY Volume 64bit RISC left after Intel butchery

      This is utter BS, go look up how many transitors the original 8086 had, then compare it with the smallest ARM you can find. The problem with low power x86 has to do with trying to achieve both low power and high performace.

      Well, I'm sorry. I should have said CISC doesn't really lend its self to low power consumtion - too many transistors relative to processing performance.

    I just got a laptop using the Athlon 4 processor. It's been on most of the day, and the keyboard and glidepoint are actually warm.

    This is an interesting way for AMD to help keep people working reasonable hours.. Here's hoping Compaq knows best. If this thing melts I'll be fairly dissapointed.

  33. Relative processor power consumption by Hoser+McMoose · · Score: 3, Informative

    Just FWIW, here's a couple processor heat numbers:

    Desktop AMD AthlonXP 2000+ : 70.0W Max/62.0W typ
    Desktop Intel P4 2.0GHz : 75.3W TDP
    Desktop Intel P4 2.0A : 52.4W TDP
    Mobile AMD Athlon4 1500+ : 25.0W TDP
    Mobile Intel P4-M 1.6GHz : 30.0W TDP
    Mobile Intel PIII-M 1.2GHz : 22.0W TDP

    AMD Alchemy Au1100 400MHz : 0.25W Max
    Intel XScale PX250 400MHz : 0.30W Max

    Max = Maximum possible real-world power consumed by the chip
    Typ = Typical power use under heavy processing
    TDP = Thermal Design Power, usually just slightly higher then typical power, though it's defined by the manufacturer

    So, just to keep things in perspective, we're talking about these embedded chips using two orders of magnitude less power then even laptop x86 chips. Now, obviously the performance isn't going to be at all the same, but in terms of power, it doesn't make any sense at all to compare the power consumption of either.

    Ohh, and just for fun, here's one more chip:

    Intel Intanium 800MHz : 130W Max

    Am I the only one that's worried that the next step in computer mods is going to take a page from rice rockets?! ie mods that do absolutely nothing useful but make a HUGE racket?!

    I can just see it now, some 3133t d00d show's up at a LAN party driving a Honda Civic with a 5" exhaust pipe, whiping out his computer that has a special noise maker attached to the rear fan duct so that the air leaving his case makes 4 times as much noise as normal.

  35. "Deltic" = "Doesn't Like Spellcheckers" :-) by billstewart · · Score: 1
    Yes, there are some people whose brains are wired a bit differently and just can't get spelling right, just as some people are dyslexic or have other minor wetware glitches. It always surprises me the number of bad spellers I run into in the computer business, because their primary job includes getting syntax and spelling perfectly correct in a language that's not their mother toungue, but it's pretty common; perhaps there's enough feedback loop in programming that you get trained to do everything correct and you didn't have that when you were learning English's pseudorandom excuses for spelling rules.

    But that's no excuse for misspellings in material you're typing into a computer that has a spellchecker -- if you know you can't spell, or if you spell fine but type badly, there's a tool right there that'll fix the problem - use it!. It may still give you bad advice about correct words to use, so if you don't grok spelling or if English isn't your first language, you'll occasionally have incorrect words, but it's an easy start. There are also grammar checkers, but they unfortunately haven't reached really high quality, so a lot of their advice is bogus.

    While I dislike most of Microsoft Office, one thing I really like is the user interface for the spellchecker. It doesn't jump out and dialog-box you, it just quietly underlines words or sentences it doesn't like in red or green squigglies. You can right-click on one and you'll get its comment about the word or sentence, and may offer you alternatives - sometimes it even offers you useful alternatives :-)
