| Abstract: | The design of this article is based on the FPGA.accdoding to the principle if the FIR and the filter with strict linear phase has even symmetry properties give 4 structure of filter,such as dircet multiplier structure,multiplier multiplexing structure,multiplexing multiplier strcture and Daalgorithm.The design of this article given the above algorithm structure diagram.Though the programming of FPGA to realize the above algorithm,then provide the resource table of variety of algorithms to compare algorithm. |
