Impulse Response Filter plays an important part in digital signal processing applications such as video, audio and image processing. The performance of FIR filter is improved by using efficient multipliers and adders. In this paper 8 tap parallel microprogrammed FIR filter architecture is implemented using Wallace tree and Vedic multiplier. The designs are realized using Xilinx Virtex-5 FPGA. FPGA results are presented and analyzed. Implementation theresults are presented and analyzed. Based on the implementation results, parallel FIR filter using Wallace tree multiplier/carry skip adder combination proves to be more efficient as compared to other multiplier/adder combinations both Wallace tree and Vedic multiplier compared to the existing work. Hence proposed method is more efficient.
