I'm using the firs.asm function in the CSL3.00.00 library for the C5505 DSP. I have a symmetric filter with even number of taps. I feed both the x and h vectors into the function, and specify nh = length(h)/2, to account for symmetry.
I see it works fine for even number of taps, but how do I indicate to the function that I have symmetric filter with odd number of taps?
