Abstract: A lot of process of DFF is used in in1age process and the image pixels ale 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 Muhiprocess Unit analyses a parallel processing method of DFT and the structure of Muhiprocess and then provides a method of Discrete Fourier Transform which make the system implement effectively.

Key words: Muhiprocess, long a dimension DFT, DSP
