I am interested in knowing how quickly the Sun-3 to Mercury ZIP 3232+ (or similar array processor) interface runs. For example, suppose you want to multiply two 32 bit real numbers A and B using the ZIP. Assume that the multiply routine is already resident in the ZIP. The overall multiply will require two DMA calls and a routine (multiply) call to the ZIP. How long does this take? (what I am asking is what is the "real" overhead in using this array processor over the VME bus?) If anyone has run some benchmarks I whould love to converse with them by phone/mail. I am Benjamin Ward, Tektronix Inc. 50-370, Beaverton, OR 97077, (503)627-6024, with a net address of tektronix!tekgvs!benw. Please respond directly and thank you to anyone who does respond.
