fft代码,采用蝶形算法,包括C,matlab和verilog代码-fft code, using butterfly algorithm, including C, matlab and Verilog code

verilog语言实在点变换DFT源代码，可以配合软核或者其他CPU进行综合FFT变换，也可以单独使用生成module！-verilog language is point FFT transform source code, can tie in with the soft-core CPU, or other integrated FFT transform, it can be used to generate module!
