摘要

Fast Fourier transform is adopted in many applications. Through the study of the character of the radix-2 and radix-4 decimation-in-time Cooley-Turkey FFT algorithm, a kind of high performance FFT/IFFT processor is proposed. With the modified radix-4 butterfly unit it can process stride-by-2 permutation. The processor allows conflict-free access of the four operands distributed over parallel memory modules. Simulation result shows that the processor can be used in many situations demanding high speed and area.
