This paper deals with the implementation of a fast method to develop a Fourier transform applied in the field of image processing. The design of the system depends on controlling the flow of input data corresponding to the data of sines and cosines according to the look up tables. The system gives a good advantage of a fast method as well as the software and hardware implementation.
