Is that really a huge amount of hardware, given how many transistors/gates a modern ASIC has? For example, from the Ethervideo list: }> http://www.streamprocessors.com/streamprocessors/resources/resource/PB005_SP16HP.pdf }> }> I wonder how much one of these costs. } } Hard to tell from 2 pages of marketing acronym soup, but this thing } is some sort of DSP that can run 16 things in parallel?

BTW this may be the fast DSP we couldn't find awhile back, and might be a good addition to OGC. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
