A Review: FIR Filteroptimization Using MCM and CSE Method

Complexity of many digital signal processing (DSP) systems reduced by a Multiple Constant Multiplication (MCM) operation. For the better performance of digital signal processing systems, Multiple Constant Multiplication (MCM) operation is not sufficient. To get better results some other operations are used with MCM. Thus, this paper introduces a Common Sub expression Elimination (CSE) operation with MCM operation. With the help of these techniques problems in the optimization of finite impulse response(FIR) filter design can be solved by decreasing the number of operators. Using These Techniques show the efficiency by reducing area when compared to previously used algorithms designed.
