Like many other DSP devices, the C54x has special instructions for FIR
filtering. In
this document:
http://focus.ti.com/lit/ug/spru429a/spru429a.pdf
look on pg 51, note the RTP instruction -- the single instruction that follows
(next
line) is the innermost FIR filter multiply-accumulate operation, repeated for
the
number of filter taps (coefficients).
This document also shows some C55x FIR filter code.
