Fast Fourier Transform (FFT) is the Discrete Fourier Transform Algorithm, which is the discrete Fourier transform of the odd and even, true, real and other properties, on the discrete Fourier transform algorithm was modified to obtain. Fourier transform theory it is not a new discovery, but for the computer systems or digital systems using discrete Fourier transform, can be said that a big step into. Digital signal processor (DSP) is a programmable high-performance processor, developed rapidly in recent years. It is not only applicable to digital signal processing, and image processing, speech processing, communications and other fields has been widely used. General computing speed of microprocessors is difficult to adapt in real-time signal processing requirements. Contact Shanghai high-speed processor integrated hardware multiplier, can carry large amounts of data fast multiplication and addition operations. Fast Fourier Transform (FFT) of the DFR s emergence made in practical applic
