I also have an interest in testing the Green Arrays GA144 multiprocessor. This device has 144 processors running at 666 MIPS each consuming less than a Watt with all running full bore. They are async processors and stop on a dime when waiting for input dropping power consumption to virtually nothing (100 nW per processor) able to resume processing at full speed in a fraction of a ns. They just need to identify a killer app and these devices will take off.
Oh wow, I hadn't heard of the GA144. It's another Chuck Moore special, and it looks REALLY spectacular. I must get my hands on one of these. Have you managed to get samples?
The one aspect that may turn off a lot of potential users is the tiny on-chip memory, only 64 words in each processor. But external memory can be connected of course. This chip is not programmed in C, so you can do a lot more with very little memory. I think of it more like an FPGA than an MCU. A Field Programmable Processor Array, FPPA.
Well, that just requires an adjustment to peoples' way of thinking. Far too many people who call themselves "embedded systems designers" these days think an "embedded system" is a big SBC running some variant of Windows with bloated C++ code eating dozens of megabytes of memory. Truly high-tech stuff like the GA144 simply isn't targeted at that part of the world.
