An Efficient Implementation of FIR Filter Using High Speed Adders For Signal Processing Applications

Numerous applications of Finite Impulse Response (FIR) Filter have been found in many signal processing applications, biomedical applications, de-noising, etc., It is essential to design the FIR filter with high speed and low power consumption. In this proposed work, design of FIR filter has been made with parallel prefix adders such as, Brent Kung adder, Kogge stone adder, Ladner Fischer adder and Han Carlson adder. The performance results are compared with the conventional ripple carry adder-based FIR Filter. Simulation was carried out using Xilinx version 14.2 and the quality evaluation matrices such as power; area and delay were measured using Cadence 180nm technology. Comparative analysis for the proposed design outperformance is measured in terms of power, area, and delay. To validate the proposed model the experimental results are compared with conventional ripple carry adder-based FIR filter.
