FFT算法的DSP的实现。DSP芯片的出现使FFT的实现方法变得更为方便.由于多数DSP芯片都能在一个指令周期内完成一次乘法和一次加法,而且提供专门的FFT指令,使得FFT算法在DSP芯片上实现的速度更快 -FFT algorithm for the realization of the DSP. The emergence of DSP chips in the realization of FFT method becomes more convenient. Since the majority of DSP chips in one instruction cycle can be completed within one multiplication and one addition, and the FFT to provide specialized instruction, the FFT algorithm in the DSP chip speed faster
