    What's wrong with ARM? Wonderful little chips, used in all possible places. This new AMD-chip runs MIPS instructions, and while the new JVM techniques from Sun (Monty) might be ported to MIPS also ARM dominates totally in the wireless world (which will replace PDAs)


    Symbian [symbian.com] OS runs exclusively on ARM processors, and with the backing of _everyone_ in the mobile industry, that's a momentum you can't ignore.


    Oh, right. Intel has the XScale (next-gen StrongArm) so AMD has to fight back :/ Here we go again, although this time, they're not binary compatible!

    • Geez, God forbid that we have more than one instruction set available for the embedded market. There's nothing wrong with ARM, but there's nothing wrong with MIPs either, and a little competition never hurt.

      • There's nothing wrong with the ARM instruction set.

        There's nothing wrong with the MIPS instruction set. However, like most "classic" RISC instruction sets, it has poor code density. This doesn't matter much in the workstation market, but in the embedded market it can be very important sometimes.

        Competition is good thing, but it seems to me like ARM is a better instruction set for the market.
        • 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.

          There are plenty of embedded niches left to fill, and I'm sure this will find it's way into a few of them.

        • Erm, ARM is 32-bit. MIPS is 32-bit. Both has 16-bit instruction size variants, Thumb and MIPS16 (IIRC). So in terms of code density there is not too much to choose between the two.

          This chip is going to compete against the XScale processors primarily, and the other ARM based PDA processors as well from Motorola and TI. It is not going to be easy for AMD of course.

          However if the processors are significantly more powerful than the previous two, then they have a good chance...

          • RISC code generally takes more instructions per Thing That You'd Want To Do than CISC code. So even if each instruction is the same size, the RISC code will be less dense.
          • My impression, I could be mistaken, was that MIPS16 was simply a 16-bit variant of the MIPS instruction set, and not capable of being arbitrarily intermixed with ordinary MIPS instructions.
        • You do realize that the "R" in "ARM" stands for RISC, right? You know, "Advanced RISC Machines"?

          • by orz ( 88387 )
            I realize that ARM is called a RISC instruction set, and has all the RISC goodness: load/store instructions, 3-operand arithmetic, simple decode, simple operations, and (almost) a flat register file. However, unlike "classic" RISC instruction sets, it has multiple instruction sizes, and therefore achieves noticably better code density.
    • Power consuption is the bottom line! ARM kicks the living shit out of x86 by a factor of 2 or 3, but MIPS kicks the shit out of ARM by that much again.

      You can piss away 5 watts to run a 133 mhz pentium, you can use a moderate 2 watts to run an ARM of equivilant computational power, or you can spend 300mW (.3 watts) to run a MIPS chip with the same might. Any questions?

    Strange, we see AMD branching out, moving into what would seem to be an obvious market, and people bitch about it (jeering their desktop procs, etc), and yet, the same crowd can bitch about MS and AOL and Intel (and any other big corp) monopolizing their respective markets.... AMD branching out forces existing players into re-thinking their current and future strategies, creates new opportunities and possibilities, and gives end-users more choices in the marketplace. All kewl... It is always good to hear of additional competitors for my (our) dollars. Go to it, AMD.
    • Just one note, the consumers in this case, are large corporations and embedded systems developers. 99% of the population will never shoose their car's CPU architecture, so the point is rpetty moot in a consumer sence.

      PS: AMD in MIPS is not so much of a big deal. There are MIPS in the mebedded market already, so the portting issue is only relevent if a company has used strongARM, etc.. derivatives in the past.

    Needless to say, I don't like this till I know exactly what these controllers do. Till then, I'll stay away from this product.
    • secure digital [sandisk.com] is a lot like compact flash. it is also used in the zaurus [sharp-usa.com], though the zaurus also has a compact flash slot.
    • I don't know if it's still true, but in addition to SD, the 1100 also has the I2S I/O interface, which also has closed-ness problems. It'd be interesting to see what kind of driver support comes with the chip for Linux - will you be able to get open-source information on things you want to plug in to those busses.

      For my applications, I like the 1500 better - it's got two Ethernet controllers built-in, so you should be able to make a variety of little router boxes. (With the 1100, there's only one built-in Ether, but there's a PCMCIA controller and a PCI controller, so you can add things easily enough, and building a wireless gateway should be easy with any of the parts.) And there's a 1500 development board which provides all sorts of physical interfaces and the different glue controllers, like PCMCIA, so a non-hardware-person like me can put together a system to try it out. Wonder when the 1100 will get one?

    I'm always seeing companies targetting the embedded systems and webpad markets with new products, but where are the webpads?

    I would have thought in '98 with the amount of press and press releasing surrounding the webpad idea we'd be swimming in low cost options by now and I'd happily be reading slashdot on the couch, but I've been sorely disappointed.

    Does anybody have any idea when a mid cost wireless webpad will show up that actually makes this market worth targetting?

      That last one is a bit more flexible. Of course, I don't picture AMD competing in either market, but that could just be me. Personally, the web pads are here and make sitting on the couch much more interesting.

    • Business.

      Eg: Trucking Companies / Cargo Companies.

      Any high volume -> high management business can usually be streamlined. I know a number of companies (trucking+cargo) which employ 'pads'.
    • Yep, agreed. Moreover, I don't see any missing technology. There only need to be somebody to stick the pieces together.

      I webpad would be a laptop that has the screen where the keyboard usualy is (and instead of it). Instead of the screen, there would be a protective plastic plate which would flip all the way over and clip behind.

      It should problably ship with a wireless keyboard & mouse combo and a detachable stand. This way, would could quickly tranform your webpad into a confortable workstation.

      The greatest thing is, as a workstation, the pad's touchscreen would be wonderful for cooperative work and pair programming session - one coder one the keyboard, and one coder with the stylus.

    Just wondering...

  • amd au1100 - 400 MHz, 250 mWatts, mips core + mac, etc..
    intel pxa250 - 400 MHz, 300 mWatts, StrongArm + mac, etc..

  • Now I can have AMD make my wireless Monitor...
    wireless Monitor [slashdot.org]
  • Imagine a beowulf cluster of those.
  • Webpads as a market seem to suffer from always-rising-expectations.

    A few years ago 800x600, 256 color, a few hours battery life and a 56KB/sec wireless connection, cost $1,000 would have stolen the show. Now it's gotta be 1024x768, full color, last 8 or more hours, be capable of playing back mp3s and video, tie into some sort of low-cost wireless system, preferably 802.11?, and cost $500.

    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.

    What the industry and consumers wants is a 'home server' system with a 'pad' attached to it.

    You don't need much in the pad. Remember this:

    lcd screen.
    Li-ION battery
    802.11b wireless
    Touch screen

    And enough ram/rom/flash to boot an XTERM - or in windows terms, "terminal server" application.

    The truth of it all is this, I don't want the 'power' in my hand. I don't need it for 95% of what I do. A big fat server box - with all the mips it needs, and an Xterm session back to the server.

    Think about it - how did the Audry, NetApplience and all those other funky devices come about. People do *NOT* want a pay-service but they do want the device.

    So strip the device - and make/sell a cheap Xterm.

    Imagine - kids in class roooms. Every kid gets a tablet - they are all wireless and they all tie into the school computer system.

    Same app - when kid needs to sit infront of a real computer, they can boot linux - which runs as nothing more then an xterm to a big server box.

    When kid goes home - kid can run any 'xterm' package and connect via ssh into the school system. Read their books, and do what they want.

    It's a hell of a deal, and it is cheap.

    Big capital expendiature - but it is doable.
    • Being an AMD, its probably going to be cheaper. Plus, the MIPS architecture rocks, and is relatively easy to program in.

      So, yes, its doable, and a portable terminal would be really clever.

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.

      • "The real problem is that CISC doesn't really lend its self to low power consumtion - too many transistors."

        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.

      no one in their right mind would have predicted Intel or AMD would keep it going this long.

      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 ?

    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
