fft，verilog

这个是利用IP内核写的fft，建议私人不要下载（不过里面还有其他可参考的文件），youIP核的人可以下载参考

% function [y exp_out] = fft_model（xNINVERSE）         
%                                                                                             
%   calculates the complex block-floating point FFT/IFFT of length N of a                     
%   complex input vector x                                                                    
%                                                                                             
%   Inputs:   x          : Input complex vector of length B*N where B is                     
%                          the number of blocks over which the length-N FFT is to             
%                          be applied. If the length of the vector is not                     
%                          an integral multiple of N zeros are
