| Abstract: | A method of implementing FFT was presented on the basis of FFT algorithm of radix 2.By using the mechanism of block-float,the range of data was dynamically increased and the advantage of speed and precision was compromised.Each component was separately designed,so that it was easy to realize FFT operation on more points.Verilog language was used in programming,and the program was synthesized and simulated in Quartus II and Modelsim.The simulation result of Modelsim was compared with that of Matlab to verify... |
