No, it's similar to the Transputer, although a little simpler - GA144 "links" are parallel (Transputer links were serial), and you can execute instructions directly. > I also like the ability to configure a core to run instructions from > one of it I/O ports - I think this is a new way of running an > umbilical system, and it makes the inter-core communication possible. > Probably asynchronous clocking pre-dates synchronous too, but allows > lower power consumption. Everyone interested in how you do parallel computing should study the Transputer - this is a more then 30 year old design, and it does many things similar to what Chuck does now. I think it also invalidates all his patent portfolio claims (transputer had PLLs, they had a fair amount of power-saving dynamic stuff, they had on-chip SRAM, they had a stack- based architecture with multiple sequential instructions packed into one word, etc.), but it is probably more expensive to proof that in court than the license fee (that's how patent trolls operate). Chuck certainly has an even further simplified approach, because that's what Chuck does: simplify to the min. >> In so far, as the map is not the territory, I think Chuck used an >> ancient path and wandered off what makes sense today. > This logic only works if power consumption is irrelevant - Chuck is > following a path that happens to minimise power consumption. > Why does this not make sense today? (Especially for nanobots). Well, one GA144 core to minimize power makes sense - that's how I deployed my b16 - as deeply embedded controller in a small part of a chip, doing the more complex digital control and some calculations. The point of using one of them is that your task doesn't even need the computation power of one - the last commercial b16 project I've done required 5000 cycles of activity per second. The only point of using 144 is to actually do something with them, and not have them sitting around idle (having one sitting around idle is ok, since you can't have less than one, and "run to finish" is a good strategy to save power). However, the GA144 is not really good at calculating stuff. I've been critizied here for comparing GPGPUs with the GA144, because a GPGPU consumes 100s of watts. Yes, but it then delivers teraflops. If you scale it down to 0.5W or so (similar power consumption as a GA144), you still have several gigaflops - and this is not hypothetical, it's what small GPUs like ARM's Mali do.

He doesn't actually get money out of that scheme, his patent troll doesn't give him his share. Chuck's designs are more in the direction of Saint Exuperie - "perfection is reached when there's nothing left to take away" - rather than traditional engineering achievements, where people add things on top of more things.
