DFT(Discrete Fourier Transformation)是数字信号分析与处理如图形、语音及图像等领域的重要变换工具，直接计算DFT的计算量与变换区间长度N的平方成正比。当N较大时，因计算量太大，直接用DFT算法进行谱分析和信号的实时处理是不切实际的。快速傅立叶变换(Fast Fourier Transformation，简称FFT)使DFT运算效率提高1～2个数量级。其原因是当N较大时，对DFT进行了基4和基2分解运算。FFT算法除了必需的数据存储器ram和旋转因子rom外，仍

实现功能：基8实现64点FFT处理器（进行两次8点FFT计算，采用基8进行64点）
详细说明：硬件结构包括六部分，分别为输入模块、8点FFT模块、乘法模块、顺序调整模块、输出模块和总控制模块。
其中，输入模块的主要功能是将串行输入的64个数据进行分类，分成8批次，每次8个输入到8点FFT模块中进行计算。
8点FFT模块：FFT是DFT的快速算法，当点数较大时，可以较大的减少DFT的运算量。常用的FFT算法主要有两种，分别为按时间抽选的FFT算法（DIT-FFT）和按频率抽选的FFT算
