I am trying to optimize some high-speed audio code for the Motorola
56001 DSP, and it seems that I could save a good amount of time by
writing a better SSI (audio sample) interrupt handler.  Since our
processing is buffer oriented and not per-sample, it would help to
have the incoming samples deposited in a double-buffering system.

Ideally, I would like the ISR to fill up one buffer, set a flag for
the main loop, and then start filling the other buffer.  A main loop
running at lower priority would process each buffer when the flag is
set.

It seems like the kind of thing that would have been done before, but
I haven't seen any code that does this.

If anyone knows of any available code or pointers to literature,
please post or Email.

Thanks!
