Sun Working to Obsolete Motherboards

perl_camel_jockey writes "Sun is developing a new technology that promises to increase computing power by eliminating the need for physical, soldered chip-to-chip connections on the motherboard. Called 'proximity communications', it portends the ability for chips to talk to one another wirelessly just by being next to each other. Potential applications in computer design abound. Apparently this is part of Sun's Hero program, recipient of a $50 million grant from DARPA's High Productivity Computing Systems program to rejuvenate supercomputing in the US and regain the lead lost to Japan, in particular to NEC's Earth Simulator, ranked as the most powerful supercomputer in the world."

Moderators are only given three choices for a post: +1, 0, and -1.

      Assume 100% of the people reading a post find it very informative. If only one of those readers moderates, that post is going to get a 0, 1, 2, or 3 (depending on the person who submitted the post).

      Conversely, assume 60% of the readers find a post mildly informative, and 40% of the moderators believe a post is horribly misinformed. If 30 of those readers moderate, that post is going to always get a 5.

      In other words, browsing at +5 doesn't mean "show me the best posts." Slashdot is designed so that browsing at +5 means "show me the posts that have been seen by the largest number of readers with mod points." Articles, because they are seen by so many readers, will always be at +5 or -1, and almost never anything in between.

Commercial range is pretty decent for most applications; the average user wouldn't expect their computer innards to be heating up past 150 Farenheit. Anyhow, the simpler chips we make operate differently at different temperatures (the part I'm working on now is rated +- 100 parts per million).

    A more complicated way of making these is to make what's called an Oven-Controlled model - you basically create a little oven that responds to the temperature of the chip, keeping it at a certain optimal temperature. These parts are much more stable and accurate; they vary in parts per billion. Dust is a big concern during manufacture; they're pretty sensitive, but once they're sealed, they're more or less set to go.

    I asked my boss about it, since he's been working here in Silicon Valley for thirty years and knows many of the interesting people (not the ones with lots of money -- the ones that invent things, like FORTH). His reply "They're smoking crack. They've poured tons of money into that for YEARS and have yet to produce anything viable."

    Even if they manage to get the coupling working, there's the problem of constrained path placement. It'll be like playing four (or six)-sided dominoes when there's four thousand combinations of dots.

    If this is really one of the "first" (I know it isn't *the first* attempt, but another attempt) attempts to take CPU and supporting chipsets "3D"? That is, manufacture the IC chips (the bits of silicon), then "stack" them aligning the connectors (or whatever) on the edges to allow for more processing power in the same (or nearly same) space? It may not be this, exactly, but perhaps the technology developed will help lead to this?

      This isn't a "3D" stacking technology. The chips that communicate have to be mounted face to face. See the illustration in Sun's technical paper.

      For an example of true 3D chip stacking, see Infineon's SOLID technology. Infineon announced that in 2002. Intel and Sharp have also played around with similar approaches.

      The Infineon approach is interesting because it puts a layer of copper between the chips. Getting heat out of the middle of the stack is a major problem with all stacking schemes. Infineon claims to address this, but it's not clear how well. You're probably not going to stack up a pile of 50 watt CPUs with this technology. RAM, maybe. Low-duty-cycle flash memory, no problem. Music players are the obvious application.

      Not much seems to have come from that technology since the 2002 announcement. So far, none of these stacking schemes have been useful. They're smaller, but not cheaper.

      I see what you're saying - looking at the Sun tech paper shows that the "connections" are at the edges of the chip, and face-to-face is needed (that is, the connections don't go through the silicon substrate). Infineon's tech is true stacking - so I wonder if the two techs couldn't be combined in some manner? That is, allowing the capacitive "connecting" surfaces (I know they are truely connected, just a capacitive junction, like is used in audio and rf) to be placed on top and bottom surfaces of the chip substrate (whereas now they are only on the "top" surface).

      I also wasn't thinking of "50 watt CPUs" for this technology - but rather something like silicon-based neurons - where a 3D approach is needed for maximum number of interconnects. Running in parallel, but at modest speeds, a "cube" of such "neurons" wouldn't put out much heat at all (and Infineon does claim good heat disipation). I am looking at the idea of hardware neural net CPU's - not serial "Von-Neumaan" architectures.

      Of course, your last line is telling - in that not much progress or use has been made with any of this technology. In time, though, it will - it has to (or something else - but this seems like the most logical course so far), to help continue the exponential increase in speed and power (flops) for CPU's (at least, that is the current trend)...

  67. As an EE I've done this by Joe+'Nova' · · Score: 1

    I've sent power over a video signal wire, and they were happily coexistant.

    What would be interesting is to know the frequencies they are using, because a transmitter(it is what it mimics) has an antenna radiating length associated with it.

    At insanely fast speeds(gHz), it shortens the size of the antenna needed. Now, suppose you get a chip lead length(same chip) that is this wavelength-you broadcast signal to itself. Not good. My guess-they use a non-harmonic(multiple of that wavelength-and antenna length) to couple the signals at the speed they want. Tuning the chips to be EXACTLY that distance from each other will be a trick, but, as they have said, it is possible in theory. One problem is chips cross modulating each other, unless they run at exactly the same clock speed, and you would need to distribute it, as well as power, to each chip. Power can be distributed in the clock signal,(but it would have to be away from the signal lines), and filtered with diodes/capacitors. The chips themselves would act as mini microwave xmit-recievers. Neat!

    Hacking one of these things will be difficult. Since you would want to run all chips off one system clock, it would be easier to analyse signals off monitors/internet cables, HD load waveforms, etc. than the chips themselves. There is another article about blocking wifi not cellphone use. Use same thing on the case. Not saying you couldn't detect/inject signals, but you would need to do some kinna hack job! You would start melting things before you succeed?

    My fear is cell phones will somewhere use this, without antihack precautions(who cares, eh?), allowing all kinds of wackiness.
