| Abstract: | In view of the current wide demands of Fast Fourier Transform application in digital signal processing field, this paper introduces the method of realizes a 8-point Radix-2 and DIT （ decimation in time ） FFT processor based on the analysis of FFT algorithm. Then, the design is synthesized on Xilinx xc3sl500 chip family, and simulated using Modelsim SE 6.0. Results indicated that this processor function precision. realizes correctly, and has high operating speed and |
