But since I guess it doesn't provide fixed or floading point arithmetic programming effects migh be really hard :-( A DSP (Digital Signal Processor) normally provide sophisticatted fixed-point (preferred by me) or floating-point support and are much faster (the Motorola 56000, I played with, executes all instruction in one cycle and two of these parallel ...) > Email me for more info (I wrote something up for someone else > interested that I can forward), and we definitely need to get a group > together of people who have the interest and ability to design such > hardware. The analog end is the hardest IMO.
