NVIDIA Enters the Mobile CPU Market 97

Posted by kdawson from the or-should-we-say-mobile-gpu dept.
Vigile writes "NVIDIA just announced the new Tegra line, a complete system architecture on one chip. Built around a licensed x86 ARM 11 CPU, this tiny chip (smaller than a US dime) includes a processor, memory controller, southbridge, and 3D and video processors. The SoC design is meant to give iPhone-type devices a more impressive visual experiences while maintaining idle power consumption under 100 mW. While not a direct competitor to Intel's Atom or VIA's Nano processors, the NVIDIA Tegra will no doubt push the envelope in handhelds and cement NVIDIA's place in the world of computing going forward."

    I am really hoping that they plan on expanding the lineup of supported operating systems. Obviously Windows is never going to happen, this being an ARM core; but Linux would be nice. In particular, Linux is pretty much the only way that this chip will have any shot of crawling out of the smartphone/PMP ghetto and making its way into general purpose small computers(I'd love to see a laptop built around something of this sort).

    Windows CE just isn't a very pleasant OS period, and its flaws really start to show once you get outside of the smartphone market, where at least it has some experience, or the thin-client market, where abject suck doesn't matter too much. Whether or not you like Linux or Windows better, you'd be hard pressed to argue that Windows CE is better for anything resembling a real computer. Unfortunately, given that this is Nvidia, and the chip looks tuned to "support premium content" I'm not going to be holding my breath. It's a pity, really. This setup looks rather cooler than Atom, and capable of some really fun stuff, but I'm not sure how good the odds are of it ever making its way into a mininotebook or small desktop form factor.

        We have a multi-hundred MHz ARM in a cell phone/PDA these days, with a display controller and a bunch of peripherals built in to the same chip. That's enough to do an EEEPC - perhaps using q bit more RAM than is standard in a phone.

        If you were really keen you could stuff a few extra 1x2inch ARM cards in the box and have a Beowulf cluster in a sub-laptop box.

        The sub-notebook is nothing new. I have an old Psion7 (http://newth.net/psion7/index.html) that must be 6 or seven years old now. It was a bit slow, but only had a 100MHz StrongARM CPU. A re-jig with a modern 600MHz+ ARM would fly!

        As for WinCE, I know that it can be made to act something like a real desktop/notebook OS, I've used and deployed loads of HP "semithin" clients(mostly citrix or RDP; but limited builds of IE, WMP, etc are available locally) running WinCE of various versions, and I've used a few PDAs running it. It just doesn't measure up as a desktop OS. It looks just enough like Windows to screw with your expectations; but doesn't run Windows programs, use Windows drivers, or even behave all that much like Windows in terms of shell look and feel. Given their sterling performance with "Vista capable/ready" I'm sure that MS marketing would have no trouble explaining to Cletus and Maybell User why their bargain bin software won't run on that Windows...

        Essentially, WinCE suffers from the majority of the shortcomings commonly ascribed to running a non-Windows OS on the desktop, without possessing any significant upsides.

      Linux and ARM are great partners. There are probably more ARM Linux systems than x86 Linux systems (if you count all those ARM Linux cell phones as systems).

      The only valid reason to design in x86 these days is to run Windows. ARM is lower wattage and cheaper. Once you look at whole systems costs (battery etc) ARM comes out streets ahead. Most OSS can be readily redeployed on ARM. There is even an ARM Ubuntu.

      WinCE is a very limited architecture and has no support for SMP etc. It is basically a toy version of Windows.

      The Eee shows that any processor that can drive a web browser and an e-mail program can be the core of a successful sub-notebook. In NVidia's shoes, I would invest a decent amount of money to make sure Gnash runs fine on it and is as compatible with Flash as compatibility can be.

    • Obviously Windows is never going to happen

      Why not? Windows currently runs on X86 and Itanium architectures. NT4 also ran on MIPS, and Alpha, if I remember correctly. If a processor gets popular enough, you better believe that MS will support it to generate sales. (BTW, Windows Mobile runs on ARM cores.)

        The main problem, even if MS were willing to put the resources into a port, is that Window's value is severely reduced without its massive library of third party stuff. Since the overwhelming majority of the Windows ecosystem is proprietary in nature, and much of it made by outfits other than MS, it would be an absolute miracle if MS were able to get more than a tiny bit of it ported over.

        As for the various NT ports, they aren't an encouraging picture. NT MIPS and Alpha are dead, XP for Itanium is dead, and there is no Vista for Itanium. Only Windows Server and a few of its variants are still alive. And look at the slow pace of the x86/x86_64 transition.

        I suspect that limited platform support is a decent business decision for MS, they aren't stupid, and they probably know better than we do how much fun it would be to attempt to bludgeon every last software vendor for Windows into shipping multiarchitecture support; but I seriously doubt that anything short of the probable extinction of the x86 architecture would motiveate a wholesale move on MS' part.(Maybe a stopgap of some sort, x86 virtualization built into the kernel or similar, or a move of existing MS tech to a new environment .NET on WinCE or Singularity or something; but classic NT and friends not so much).

        To support a CPU is not enough. ARM cpu cores will typically connect to an AMBA bus (like hypertransport), but these SoCs will usually have the entire bus internal. You'll have a whole set of peripherals which need to be programmed all over again with little or no code reuse from existing projects. You need to understand how these peripherals interact with the boot rom and CPU in order just to load a bootloader onto it. If you have perfect documentation, you'll still probably need at least a decent oscilloscope or logic analyzer to get a heartbeat out of it. Talk to any firmware or digital design engineer about 'board bring up' on an unproven cpu platform, and you'll likely hear quite a few nasty anecdotes.

        All this can be done, but it would save everyone a lot of time if nvidia supports Linux with a real board support package.

    Modern ARMs are very good. Much, much better than the XScales. They can come with floating point units which are many times faster than software emulation and do not drain much power. Even under load they draw much less than the atom. Also, it looks like the modern cores come with OoO, something which is missing from the atom.

    Secondly, the ASUS EEE has shown that it may not br necessary to be x86 compatible any more. It is compatible, but it has sold many copies running Linux. That means that x86 compatibility is not required, since Linux runs well on many processor types.
