Abstract

In today´s world the most widely used operation performed in DSP is finite impulse response (FIR) filtering. Design of low-complexity multiple constant multiplication (MCM) operation which reduces the complexity of many digital signal processing systems. In this paper, we design an enhanced fir filter using Graph Based algorithm. In that fir filter structure, we use modified carry save adder in the place of conventional adder. By using modified carry save adder, carry element is getting eliminated. It reduces area and power than existing one. The code is written in VHDL.
