    Does anyone know the percentage of time the CPU spends doing integer
math while executing, say, QuickDraw II calls?  If there isn't a lot of
math going on, the overhead needed to pass stuff back and forth between
the CPU and the DSP might slows things down instead of speeding it up.

    I've redirected this part of the thread (with new subject) to
csa2.programmer instead.  What kind of software are you thinking of
working on first (if it isn't a patch for SANE and IntMath)?
