A neuron is so simple that I can't imagine needing anything as complex as a a real OS. I could imagine them having a TCP/IP stack (maybe just UDP which would allow broadcast and topic based routing)</p> <p>I do remember years ago someone doing an experiment where they put, I think, 1000 MIPS processors (comparable to ARM) on a single chip.<br /> IBM have all the technology and their own processor designs to do that sort of thing.</p> <p>I believe folks have put 32+ 32-bit processors on a single FPGA (e.g. micro Blaze <a href="http://en.wikipedia.org/wiki/MicroBlaze)" rel="nofollow">http://en.wikipedia.org/wiki/MicroBlaze)</a>.</p> <p>I don't think 32-bit processors are essential. There was a machine called the connection machine <a href="http://en.wikipedia.org/wiki/Connection_Machine" rel="nofollow">http://en.wikipedia.org/wiki/Connection_Machine</a><br /> which used processor which were 1-bit serial.<br /> I'm not convinced its trade off of width vs clock was ideal, but a modern FPGA has 'cells' which are not too much simpler, so you could expect to have 10,000's of cells on a single FPGA.</p> <p>With enough on-board RAM to hold the "program", then there would be enough to do the worm, and more. </p> http://forums.leaflabs.com/topic.php?id=1494#post-9852 Thu, 22 Mar 2012 08:38:20 +0000 josheeg 9852@http://forums.leaflabs.com/ <p>Connectome and how could open source hardware make use of one?<br /> I seen ted talks on connectome and a ted talks on IBM blue brain.<br /> That made me wonder linux has clustering distributions that go on sd cards.<br /> IBMs blue brain runs some kind of connectome structure by putting 1000 artificial neurons in eatch processor of 4 refrigerator sized boxes of networked not soo large processors 16000 of them to run a neocortical column simulation.<br /> Hypotheticaly would linux be neeeded for a system like that or could maple and a fpga be one node of that system? Would it be larger and not require as many? Or would it be better suited for something like a arm8 in the beagle bone? Would it be better as pannels of processors hard wired with wires or wireless chips? </p>
