[Open-graphics] CPU on graphics card

Which means it is not an option :-(. If only the 2700g was still  
being sold...

This is another useful chip:
http://www.semicon.toshiba.co.jp/eng/product/micro/mep/document/ 
index.html
it appears to be a configurable media processor with DSP interface,  
user defined single-cycle external
interface, etc. It runs at 1Ghz, 1W!

As an alternative, this is the atmel DSP I mentioned earlier:

100Mhz, 1GFLOP:
For instance, four floating point multiplications, four floating  
point additions and two
floating point subtractions, six memory accesses and six address  
updates can be exe-
cuted simultaneously in a single instruction.

That is some serious number cruching.

It doesn't have a rating, but the Ipeak leads to around 2W in my  
calculations.

I think this discussion is turning more to the SIMD approach, which  
is more efficient.

It seems to me that the best way would be to design a small SIMD CPU  
into the FPGA
fabric. This makes it much easier to interface and we get to specify it.
