Reconfigurable FFT Processor
Design of FFT Fast Fourier Transform Processor. FFT algorithms are based on the fundamental principle of decomposing the computation of discrete Fourier Transform of a sequence of length N into successively smaller discrete Fourier transforms. There are basically two classes of FFT algorithms.
