Toshiba Uses Cell Chip In Consumer Laptop 179

Posted by kdawson from the thinking-outside-the-cell dept.
An anonymous reader sends us to CNET UK's Crave blog, where they report on a demo from CES. So far the only uses for Cell chips have been research stuff and the PS3. Now Toshiba has put a Cell chip into a consumer laptop; they are calling it the Spurs Engine. "The system was demonstrated in modified Qosmio G45 laptops, each of which uses a standard Intel Core 2 Duo CPU in addition to a Cell chip with four 1.5GHz synergistic processing elements (SPEs). Toshiba had four demos running... Demo 3... scans all your movie files, recognizes faces, and creates thumbnails of those faces. You can then click the thumbnails to watch scenes with those faces in, or compile them in a separate playlist."

However, this could "Spur" the development of applications for the Cell running on Windows and with growing adoption Microsoft might even start porting some of its own libraries. History might be in the making. Watch it unfold.

            Actually for a long time Microsoft wrote NT on the MIPS and ported to Intel. They felt that if they didn't portability would suffer. Microsoft was actually pretty serious about NT on the Alpha, MIPS, and PPC for a long while. The problem was that nobody else was. Windows developers tended to write for Win95 because that was the big market and many users of the MIPS, Alpha, and PPC where sticking with Unix since they felt it was a better server.
            Microsoft finally just gave up since 99.9% of there users where on Intel.
            Since Intel and AMD have pretty much killed the Alpha and MIPS on servers it worked out well for them.
            • Developers at Digital, on alpha machines, did the leg work on NT so it would work on 32 and 64 systems. I guess after IBM stopped giving them code, via OS/2, they had to find someone to do the work for them.
              • Not only did developers at digital do the leg work, Alpha machines that were to run windows NT had to have special co processor to convert the NT code into Alpha instructions.

                this I know for a fact as I have held in my hands an Alpha Motherbaord and have seen the clearly labeled chip for MSFT NT compatibility.

                  That's not a coprocessor. Old Alphas just needed a different BIOS with ARC support for compatibility. Later AlphaServers supported NT out-of-the-box with no labelled chip, custom BIOS, or differences at all from OpenVMS/OSF/1 or Linux support. I know this because I have an AlphaServer 4/266 running NT right now.

        IIRC, the Cell uses way too much power for sensible laptop use.

        Apparently, you do not know how CMOS devices work. The power consumption of the chip is directly proportional to the capacitive load and the frequency, and is proportional to the square of the voltage.

        Concering only the SPE power consumption, which is the majority of power used by a Cell chip:

        If x represents the power consumption of a 7-SPE chip running at 3.2 GHz...

        If you cut the number of SPEs from 7 to 4, your capacitive load is cut to %57 of the original, or 0.57 * x.

        If you again cut the frequency from 3.2 GHz to 1.5 GHz, you get a power consumption reduction of 1.5 / 3.2. Your total power consumption after capacitive load and frequency changes is 0.26 * x.

        The PPE portion of the chi[p will see power consumption reduced by half because of frequency.

        FINALLY: a reduced operating frequency means you can reduce the voltage, and this is where you can see some impressive gains. Just to get an idea of the differences in voltages, here is a link to a voltage vs speed graph for each SPE [realworldtech.com], from Sony engineers. You could potentially operate the Cell at 1.5 GHz at a very low threshold voltage, giving you a %20-30 reduced power consumption.

        So, after all that, you have a chip that runs on less than %20 of the power of its big brother (estimated 60-80w), so this chip is around 10-15w, which is quite practical for four 128-bit vector processors plus a PPE.

        Not that there's anything the Cell could really do effectively for a PC. For parallel processing, we already have dual 128-bit SSE units on the Core2 Duo processors, which comes within fighting range of four SPEs clocked at a paltry 1.5 GHz. And of course, most of there pipe-dream uses will get held-back by slow I/O on a home computer or laptop (like ALL the examples uses for this chip listed in the article), so there's really no need for all that processing power.

          The bigger your main die, the bigger % of chips need to be thrown out at the fab plant due to impurities in the manufacturing process. That lowers yield exponentially, and drives up price. At some point you have to split things off into separate chips or else your manufacturing output effectively falls to zero.

      Those had a 56001 DSP along their motorola main CPU for extra mathematical oomph, and impressive realtime visual or sound effects.

      The Quadra 660AV and 840AV had an AT&T DSP in it that handled all of the sound and video functions. It could also do voice recognition of any menu item, button, or a universal command set within a decent amount of time. It also had a telephone interface box which let it mimic a fax machine or data modem (and I say mimic, because it was horribly unreliable at the latter; fax transmissions were short enough that your chances were better), or behave as an answering machine.

      There was also exactly ONE application that I remember for the DSP aside from what Apple used the DSP for: one could use the DSP to do fractals in a fraction of the time the 68040 processor could, though the DSP ran at about twice the clock speed (25mhz vs. 55mhz I believe.) In short: utterly useless, and it was discontinued after a year or two. It did have a clever feature or two, one of which was that it could load the ROM (for those of you who don't remember, all the system toolbox commands were in ROM, not on-disk) into RAM, which would suck several precious MB- but would dramatically and noticeably speed up the system. The functionality came via a third-party hack.

      The best "feature", however, was its crashes. Given this was an old System-7/8/9 machine and 68040 based, it suffered from the usual stability problems, only multiplied by about ten-fold because of all the shit that was needed to handle the funky DSP graphics/sound/etc. The best part: the main CPU and the DSP would get out of sync during these crashes, and would feed garbage to each other. Kind of like catting /dev/random to the input of a 10-foot-tall milling machine, you have no idea what you're going to get, but it'll be impressive to watch.
