Abstract: |
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. |
