Design and Implementation of Base-6 FFT Algorithm on FPGA

A method of digital signal processing based on FPGA chip is presented. The system function is described by VHDL and circuit diagram, compiled and synthesized with MAX+plus II, and implemented in a FPGA chip in series of FLEX10K from Altera company. In this way base-6 FFT algorithm is implemented, and the simulation results are also presented. The Fast Fourier Transform(FFT) algorithm running on FPGA chip has the advantages of high speed and excellent anti-disturb capability, and the FFT algorithm designed by VHDL based on IP core can be used repeatedly so as to improve the design efficiency.
