    Multiplierless Synthesis of Multiple Constant Multiplications Using Common Subexpression Sharing With Genetic Algorithm

    In the context of multiple constant multiplications (MCM) design, we propose a novel common subexpression elimination (CSE) algorithm that models synthesis of coefficients into an estimated cost function. Alth...
