Abstract

According to the characteristics of FIR filter and distributed algorithm(DA),the theory and method of FIR Filter was realized using DA based on FPGA.On the basis of table partitioning,the designation of FIR filters was optimized by serial-parallel arithmetic aiming at filters with higher order while saving the hardware it would use.16-order FIR filters was designed by serial and parallel DA and simulated in Quartus Ⅱ 7.0.Results showed that the FIR filters were with small resource usage and high speed compared with traditional methods.
