A number of you are very keen on having a "graphics card" with some kind of CPU or DSP on it. While I don't think that that's necessarily the most effective approach, there are reasons why it might be AN approach quicker than some others.
So here's my suggestion: If you all want to have a card like this, we are capable of building one. We just don't have the resources to design it. So you design it. Obviously, there are gaps that we can fill in. But going from what you see in the OGD1 schematic, BOM, and artwork, you can see what level of detail we need. Provide that. The more you provide, the greater the likelihood we can make it. Really, the best thing would be a complete PCB design in Veribest or gEDA. While Howard, Andy, and I can't do this work (any time soon), we can guide others through the process. Time to get grease on your hands, folks. Oh, and don't shoot yourselves in the foot by trying to pack in too many features. Figure out what is the minimum to make it work and design that. If you can get that to work, then make another version with more stuff. On 4/18/07, Nicholas S-A <[EMAIL PROTECTED]> wrote:
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. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
