Big Blue Designing Chip to Decode the Big Bang 149

Posted by ScuttleMonkey
from the lighter-and-flatulence dept.
Jerry Beth writes "IBM is working with European astronomy organization Astron to design a chip that will be used to help gather billions-of-years-old radio signals from deep space in the hopes of learning more about the origins of the universe. From the article: 'It's part of Astron's Square Kilometer Array (SKA) radio telescope project. The SKA will be linked to millions of antennas collecting radio signals from space. The antennas will be spread over a large surface area of the globe but, in the aggregate, they will form a square kilometer's worth of collection area. [...] The microprocessors will essentially help the antennas capture the signals, filter out extraneous data and then convert the signals into data. Astrophysicists will then analyze the data to look for patterns. The weakest signals are the prize in this project, because they will be the oldest.'"

      Sure, and maybe next they'll use it to filter out all the crazy women in the world and find the sane ones.

        That's easy. All you need is a blinking light and a burnt-out one. You have all the women stand in a line and tell them to go into the crazy line if the blinking one comes on and the sane line if the burnt-out one comes on.

  • This is very interesting, but it doesn't explain what is being filtered, and how it is being filtered. Assuming the signals that are being filtered are radio waves, that would indicate that the processor would need to be powerful enough to catch the weak waves (as indicated in the article), while still providing enough power to filter out the noise.

    I trust the astronomists already know how to do this, but it would be interesting to see what the process would be.

    Then it brings up the other question:

      Nope, IBM offers a SiGe foundry process. If you pay for the wafers, IBM will make them, whether you want 10 or 10,000. Yes, you may be designing a chip for a limited design run, but you're also designing a telescope that you'll only build once...

      IANARA (I Am Not A Radio Astronomer) but I wonder if these are very fast correlator chips that are used to synchronize (I'm sure there's a much better technical word) multiple data streams so that the data from all the antennas in the array can be massaged to make X small antennas look like one gigantic one (in resolution). Apparently it's a process that's much faster to do in silicon (across many parallel channels) than in a general purpose CPU.

    • Correlation. That's how GPS works, for instance. GPS signals are way weaker than the noise they are embedded in. However, if you know the pattern (as you do with GPS) then you can tease the signal out of the noise.

      If you don't (as with space), then you need to make some guesses and do a whole lot more searching with a lot more patterns to find a match. That's no doubt where BigIron comes into the equation.

    I think this is great. The chips will contribute a huge amount of processing power which would be unavailable from current super computers, which will allow calculations with much greater resolution so we should learn a lot.

    It would be interesting to actually know the performance of the chips. From the article,

    The chips will be made on IBM's silicon germanium process and have a typical peak frequency, or speed, of around 200GHz. They will be made on the 130-nanometre process.

    Bearing in mind that these are ASICs and they run at 200GHz each this should allow for an incredibly detailed model to be formed. Can anyone hazard a guess to how the performance would compare to

    • I don't know if the process is good for digital logic. I think there are reasons that digital ICs are generally CMOS, but I forget the particular details. In reading the article, this looks like it may be an analog chip.

      Umm, I consider myself to be a creationist, and I'm not pissed off. It seems obvious (to me, anyway) that the Big Bang theory and the creation story are just 2 different views of the same event. The universe was created from a singularity -- where once there was nothing now there is something. Sounds like creation to me. The more we learn about the universe we live in, the more in awe I become of God, the Creator of it all. Anyway, please hold your flames to a minimum. You won't change my fundament

  • It's a chip that is designed to have little noise while operating at super high frequencies (~ 200GHz) so that the faint noise of the universe can be properly detected. Cool!

    The uses for this, shall I say "ultra low noise", technology could be highly valuable in the sensor and biometrics market. Less noise or interference is always better for any pattern recognition... ok, ok, except in chaos theory.

    Still, I'd really like to see something on the software they will use to model the universe's noise data.

    "IBM is working with European astronomy organization Astron to design a chip that will be used to help gather billions-of-years-old radio signals from deep space in the hopes of learning more about the origins of the universe.

    IBM blew past the idea to go by the book and use OCR on a Bible to get an old testament about this instead of channeling their radical (radiocal) efforts to chip away at this spacey idea of extratextual evidence.
