Note that this only supports VGA (640 x 480).
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:
http://www.atmel.com/dyn/products/product_card.asp?part_id=3395
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.
