Implementation of Kogge Stone Adder for Signal Processing Applications

Abstract: Low power system design has turn out to be a significant performance goal. The Finite Impulse Response Filter is an efficient component for digital signal processing applications. Adders and multipliers plays an essential role in implementation [R1] of FIR filter. The proposed FIR Filter is designed by using Kogge stone adder and booth multiplier. Kogge stone adder is a high speed adder which is used for designing high performance circuits and Booth multiplier is a multiplication algorithm which is used to perform multiplication by using 2’s complement notation. Thus the proposed design can reduce the delay and power consumption of FIR filter. The proposed FIR filters are designed with the help of verilog Hardware Description Language and synthesized using Xilinx ISE 12.4 tool.
