基于时间抽取的8~1024点FFT的程序及输入、输出，用TMS320C54x汇编编写，已通过调试，并对输入方波信号进行FFT变换，检验输出信号是否是一sin波形-Based on the time taken from 8 to 1024 points FFT process and the import, export, and to prepare a compilation TMS320C54x through debugging, and enter the square wave signal FFT transform, testing whether the output signal waveform is a sin
