microchips website has appnotes describing dsp routines like FFT/IFFT,
IIR,FIR for pic i dont know which
series...but it should work on pic 18 as it is still a single accumulator
design.
For C implimentations there are plenty on the web...
Hope that helps.

I am looking for an efficient fixed point FFT in C. Does someone know an
implementation on PIC18 (I know that PIC18 is not a DSP but this
question is in the frame of a feasibility study with high constraints on
costs) ?
Thanks,
