Disclosed is a Fast Fourier Transformation (FFT)/Discrete Fourier Transform (DFT) reverse sequencing system. The reverse sequencing system comprises: a signal control device, used for obtaining a control signal corresponding to data to undergo reversing at each point, and sending the control signal to a reversing device, so that the reversing device performs reversing on the data at each point according to the received control signal; the reversing device, used for reversing, according to the received control signal, the data to undergo reversing. Also disclosed is an FFT/DFT reverse sequencing method and an FFT/DFT reverse sequencing computing system. The disclosed system and method can solve the problems of the too long FFT/DFT reversing time and the low utilization of the appropriate number of processors when the vector processor performs calculation on FFT/DFT, and can also improve the FFT/DFT vector calculation efficiency. |
