Design and VLSI Implementation of A Radix-4 64 - Point FFT Processor
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2012, Vol 1, Issue 7
Abstract
It is important to develop a high-performance FFT processor to meet the requirements of real time and low cost in many different systems. So a radix-4 pipelined FFT processor based on Field Programmable Gate Array (FPGA) for Wireless Local Area Networks (WLAN) is proposed. Unlike being stored in the traditional ROM, the twiddle factors in our pipelined FFT processor can be accessed directly. A novel simple address mapping scheme and the modified radix 4 FFT also proposed. The FFT processor has two pipelines, one is in the execution of complex multiplication of the butterfly unit, and the other is between the RAM modules, which read input data, store temporary variables of butterfly unit and output the final results. Finally, the pipelined 64-point FFT processor can be completely implemented within only 67 clock cycles.
