A Broadband FFT Processor Core Based on FPGA
This paper presents an implementation of a real-time FFT processor based on FPGA,which uses the radix-4 DIF (decimation-in-frequency) algorithm.Five stages of radix-4 butterflies are used to make up of a pipeline to compute the 1024-point complex FFT.The FFT processor can operate at 164MHz and compute a 1024-point FFT at 6.225μs when operating on the device of Xilinx Virtex II Pro 70.This will accommodate a high data throughput transmitted to the back end instrument.
