- A 32 MHz DSP has a 16 MHz instruction clock rate. A 1 Mbyte/sec throughput
- corresponds to 300 KDSPwords/sec, or one interrupt every 3 us. You have time
- to execute 48 instructions then between each interrupt. Enough to do some
- pretty effects : Surround, Echo, Reverb, Basic IIR filters and much more.
-
- If you want a demo of the sound capabilities of the DSP, watch out for the
- Audio Fun Machine demo at the Comdex (Personnal pub).

- Enjoy.
