The Motorola DSP96002 does an integer multiply in 2 or 3 clocks, so a 33 MHz device does 11 million multiplies (and moves) a second. The chip costs about $50.
The 96002 is a floating point part. Last time I checked it cost several hundred dollars. I suspect that you were refering to the 56001/2 family (which does cost something like $50).
I checked the 56001 data book, but it does 24 bit integer multiplies, not 32, so I didn't quote them. The figures I gave are for a 32-bit integer multiply, right out of the 96002 data book. I haven't checked 96002 prices for a couple of years. When I last checked it was something like 200 pounds ($300) in small quantities. It has now been outclassed by the C40 and several other very good DSP chips and time has passed, so I think that in production quantities the price would at least be under the $100 mark. -- Jim Dixon
