There are many hand-held products that include Digital Signal Processing (DSP), for example, cellular phones and hearing aids. In this paper, the authors are an exact common sub expression elimination algorithm for the optimum sharing of partial terms in Multiple Constant Multiplications (MCMs). Although many efficient high-level algorithms have been proposed for the realization of Multiple Constant Multiplications (MCM) using the fewest number of addition and subtraction operations, they do not consider the low-level implementation issues that directly affect the area, delay, and power dissipation of the MCM design.
