The Implementation of Fast Fourier Transform based on FPGA

摘要

This paper introduces the arithmetic of FFT processor-Radix-2, and introduces the method and process of design and realizes a FFT processor, which is integrated in FPGA chip, regarding FPGA as design carrier.The results of hardware test of FFT processor shows that the processor works well and has high speed.The design has the advantages of simple, agility and small bulk.
