Is the ADAU1701 a suitable part for performing processing & analysis in the frequency domain?
Specifically, I need to do an FFT, spectral power density, and singular value decomposition functions on 24 bit data. The SigmaStudio software does not offer an FFT function, so I would need to build an FFT from "scratch" using the basic add, multiply and delay blocks. This seems like a bad idea--if the part was designed to do an FFT, it would be a canned function in SigmaStudio, right? Can a 1024 point FFT be implemented on the ADAU1701? If so, how much of the ADAU1701's resources would be eaten up by doing this?
