I think the only thing Chuck is missing is a few 20-somethings hackers, bent on solving an 'impossible' problem with his chips.


That's why I'm posting it here.

Some possible ideas

====================

- Sound processing (think 144 cores preforming Fourier Transforms)

- Pico Satellites (This chip has a surprisingly extreme low power requirement).

- Wireless communication (small power requirement means small batteries)

- Computer Vision processing. Imagine toys or tools that can process visual information faster than an Xbox.

- Basically anything that can be done in parallel, that is suited for small size and low power, but doesn't require much on chip memory.


Had a rough look on it's instruction set and didn't see anything resembling DSP instructions. So i'm not sure it would be great for all those uses.

On the other hand, picochip sells a 200-300 core DSP , that is being used for the wireless industry.


From this PDF http://www.greenarraychips.com/home/documents/greg/PB001-100... GreenArrays seems to think it would support DSP

"SUITABILITY: The GA144 is designed to support the largest and most demanding computing challenges that can be addressed with a modest sized die in a relatively inexpensive and easy to use package while still using well less than 650 mW in most practical applications. The geometry allows for generous numbers of parallel paths and/or pipeline stages, or for complex flowgraphs in control, simulation, or DSP applications. Clusters of nodes devoted to functions such as cryptographic algorithms are easily placed in the large array, and the cluster needed to control external memory and run a high level language from it is well out of the way but has good surface area for interaction with other functions. Use it also as a universal protoytping platform for applications destined to run on our smaller chips. "


There is a huge difference between supporting DSP and being good at DSP. My $0.50 MSP430, clocked at 32kHz, "supports" DSP.


At the very least, I'd expect instructions for things like saturated addition


I really hope these have a good application for DSP. I can imagine the sweet homebrew synths that people will be coming up with.


Video-games?

Can this replace a physics dedicated processor? What about latency?
