摘　　要：为满足机器人敏感皮肤实时信号处理的要求,系统采用FPGA来实现快速傅里叶变换(FFT)算法。本文在分析了基-2FFT算法的基础上,采用同步流水线结构,利用现场可编程门阵列(FPGA)完成256点16位复数点FFT。实验结果表明,使用FPGA实现FFT具有很好的实时性,能满足机器人敏感皮肤实时信号处理的要求。In order to meet the requirement of the real-time signal processing of robotics sensitive skin,FPGA is used to implement the fast Fourier Transform （FFT） algorithmic. This paper is dedicated to the description of design and implementation of a high speed and real-time FFT processor with FPGA.Synchronously pipelined architecture which is based on FFT algorithm of Radix 2 is utilized to achieve high throughput.Experiments show that the high-performance FPGA is suitable for complicated digital signal processing,and can meet the requirement of real-time signal processing of robotics sensitive skin.
