| Abstract: | A lot of process of DFT is used in image process and the image pixels are higher and higher.So we are used to meet with the long Discrete Fourier Transform in Image process.This paper which based on the character of the Multiprocess Unit analyses a parallel processing method of DFT and the structure of Multiprocess and then provides a method of Discrete Fourier Transform which make the system implement effectively. |
