Let me chime in with a few facts regarding DSPs. It may be review to anyone
who has programmed DSPs, but some may find it informative.
Fixed-Point vs. Floating Point DSP chips
Floating Point DSPs make the best/easiest compiler targets. Most of the
standard operations present in ANSI C translate fairly well into floating
point DSP assembly. This reduces the need for assembly
