: (6) If you really need the blazing integer speed, buy a coprocessor.
: That is also one of the fundemental RISC ideas. There are times
: when things just aren't done well by software and do need hardware
: help. This option also allows you to get *really, really* fast
I'd love to. The only problem is: How do I integrate (say) an integer DSP
chip into my SUN so it will act as a co-processor. Who modifies the compilers
to use it, etc. etc... I could rewrite the compilers but I don't have the
time. Do you know of a commercially available integer coprocessor that I
can plug into a workstation? I don't.
: integer speed by using a multiplier array (works by generating
: all the product terms all at once and then adding the whole
etc.
