This a vhdl code written to compute fft for the values stored in a RAM. The fft values are stored in bit reversed order finally in the same RAM. Not sure if it is working 100 . For my test input it worked.-This is a vhdl code written to compute fft f

快速傅立叶变换（来源《C常用算法集》） 本函数测试OK,可以在TC2.0,VC++6.0,Keil C51测试通过 如果你的MCS51系统有足够的RAM时,可以验证一下用单片机处理FFT有多么的慢。-Fast Fourier Transform (Source C commonly used algorithm sets) the function test OK, TC2.0 VC++6.0 the Keil C51 test by If the the MCS51 system yo
