摘要
提出了在现场可编程门阵列(FPGA)上实现512点基-8快速傅里叶变换(FFT)算法的设计方案.方案采用了单芯片超高速的FFT处理器结构,满足了实时信号的处理要求.通过采用基-8算法、流水线结构以及32位的浮点数据,提高了FFT的运算速度并减少了FPGA内部的资源占用.本设计方案在100MHz的时钟下,完成了512点基-8 FFT运算需要,满足了高速数字信号处理的要求.
This paper proposed the design of 512 point Radix- 8 Fast Fourier Transform（ FFT） algorithm on the Field Programmable Gate Array（ FPGA）. The scheme adopted a single chip ultra high- speed FFT processor architecture to meet the requirement of real- time signal processing. By using Radix- 8 algorithm,pipeline architecture and 32- bit floating- point data,the operation speed of FFT was improved and the FPGA internal resource usage was reduced. Under 100 MHz clock,the design scheme only needs 3. 90 μs to complete 512 point Radix- 8 FFT,which can meet the requirement of high- speed digital signal processing.
