Hi,

Digital filters are normally rahter straightforward programming.

I once did some performance test on symmetric FIR filters in software, some results in attachment (NIOSII with instruction cache, no data cache).

Before starting, I think you have to consider if you have performance enough with the pocessor, or if you need to accelerate the algorithm in logic next to the processor.

How big is the filter order estimated?
