Love the guy and his passion for its chips, but this 144-computer chip looks like a solution in search of a problem: what is trying to solve? How's the inter-core communication handled? On the other hand, creating weird chips like these, just because you can, is awesome and stimulating a hacker's mind.

Not being much of a hardware geek, I'm having a hard time evaluating how fast each core is.

From the site: "With instruction times as low as 1400 picoseconds and consuming as little as 7 picojoules of energy, each of the 144 computers can do its work with unprecedented speed for a microcontroller and yet at unprecedentedly low energy cost, transitioning between running and suspended states in gate delay times. When suspended, each of the computers uses less than 100 nanowatts."

How does this instruction time compare to other modern processors?

It sounds to me like some of the benefit to be had here may be from the low amount of power necessary per core. Power and associated cooling is a MAJOR source of cost for datacenters, and so if this really is a significantly lower power consumption (again, I don't know how much power the alternatives use), then it could have a big impact on the cost of commodity computation power.

Let me get this straight: It's basically a microcontroller timed 144? Can anyone explain to a nonhardware geek?

This example gives something of an idea:

The picture I get is that the boundary between computing components and control/sensor electronics is dissolved.

Well if you ever wanted to be 'out there' Chuck's processor would be a great place to start. Chuck Moore invented Forth and has been building machines that can run Forth efficiently for years. Think of it as a Turing machine that can do useful work. He has pushed the edge of computation per watt for years.

That being said, I've heard him talk about this chips for years and it is great to see it finally see the light of day. If you were familiar with the Transputer technology, this is a better take on that, if you are familar with FPGAs you can think of it as an FPGA with processors instead of CLBs.

Things that it can do are similar to what Intel is doing with Larrabee or some of the CUDA stuff that nVidia has done. It doesn't have a GDDR3 interface to a GB of memory so you can't custom build your own GPU, but you could do your own PhysX type engine with it.

It also makes a helluva differential cryptanalysis tool, or a signals analysis tool in general.
