hi...
i'm planning to make a thesis about demodulate AM signal Digitally and i
want to use TMS320C54. and for filtering i want to use FIR method, can it be
done?
thank you
please give me some input.

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.
