    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...

    Efficient 2D Linear-Phase IIR Filter Design and Application in Image Processing

    We present an efficient and novel procedure to design two-dimensional (2D) linearphase IIR filters with less hardware resource. A 2D linear-phase FIR filter prototype is first designed using semidefinite progr...
