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.
