【Abstract】 FFT with high speed,high precision is necessary for real-time signal processing.With the development of new programmable digital signal processing (DSP) chip and parallel processing technique,this need is becoming content.In this paper,we study the parallel situation of FFT,two kinds of parallel FFT algorithms are proposed and realized by TMS320C80.Some experiments show that the algorithms are of universal significance.更多还原
