Sugarcube CPU

1000's of Logic Units Sintered Together like a Sugarcube

Make special logic units, maybe they're even mini-cpus, that are the size of a single grain of sugar with communication connections on each surface facet. Pour 1000's into a sugarcube sized mould and perform a sintering process to glom the whole thing into an aggregate, interconnected meta CPU. Programming details and usefulness to be determined.

Oh, and its made out of silicon so it shouldn't dissolve. Well, unless you put it into a hot cup of coffee and stir vigorously.

Not much to do with the idea, but since you ask... [jutta, Sep 19 2000]

Ditto jutta, but since sugarcube cpus need storage... [GeneticCrypto, Sep 19 2000, last modified Oct 04 2004]

Okay, so I stole it from Slashdot, but this is another step closer to the nano-computer idea. Of course, at -253 C, coffee is out of the question. [centauri, Sep 19 2000, last modified Oct 04 2004]

       Maybe you can design it so that it gets its power from external heat sources, say a nice hot cup of tea.   

       How many of these little guys would I need to process Arecibo SETI data in realtime?

       IBM has developed a storage technology that they say can store a terrabyte in a device the size of a sugarcube - lost the link in a computer crash, but I think it was in 32bitsOnline.   

       It was also, as I recall now, a terrabyte on a drive the size of a dime...

       Holographic storage? They used to talk about that as being the next big thing, but not much has been said in the past few years. Scientific American had a long article on it sometime in the past year or two.

       No, I think it was actually mechanical, tiny pits in the surface of some sort of plastic, read with a tiny little tonearm, or something.

       I have read about that too. It is basically a specialized scanning tunneling microscope. Just imagine bit manipulation at the atom(ic) level.

       at some motor functions (like the communications facets being able to expand and contract the space between cubes) and you've got yourself some nanties like in sluggy freelance! (http://www.sluggy.com)

       As an independant study-type-thing in the next year I have actually set myself to designing something remarkably resembling this idea. Of course, the connections would have to be more deliberate, but the general idea is similar. I'll post more as I actually begin work (should be this summer). I might even put up a link to any VHDL code I might write.... we'll see.

       People have long wanted to take advantage of the third dimesion to make circuitry. The problem with this solution is that it presents no solution at all! How would the grains be made? Are they 3D themselves or only 2D? If they're 3D, you've not explained how they are fabricated which is the most important part.   

       If the grains are just regular 2D lithographed chips, then this device is worse than a regular IC. It requires a massive amount of interconnects. Interconnect pads are really big compared to transisters. They're thousands of times larger than a transistor. And there's no point to using such small grains anyway since fabrication technology easily allows for ~100mm^2 size chips.
