摘要：This paper proposes a novel parallel Finite Impulse Response (FIR) filter, which is based on polyphase decomposition. It can increase the running speed by M times compared with the serial FIR filter, where M is the number of sub-filters, and the parallel FIR filter only introduces very small delay. Firstly the theoretical foundation of parallel FIR filters is analyzed. An example of the floating point parallel 4-channel FIR filter is given to verify the algorithm. Then a direct form structure parallel FIR filter is designed, which has optimum fixed point coefficients. Finally the fixed point of 4-channel parallel FIR filter is implemented in Xilinx’s Virtex-6 Field Programmable Gate Array (FPGA). According to the simulation results, this filter has smaller resource consumption and its sampling rate up to 1GHz.
