For this purpose, the minima of an objective function is achieved, constructed as sum of integral mean squared error with allowable tolerable limits to control ripples in passband and stopband region, and the dynamic power that has computed through hamming distance (HD) between two successive filter coefficients. The novel extract of this paper is three fold: first, enhancement of the power performance by reducing the switching activity second, raising adder efficiency using newly proposed hybrid CSE algorithm and third, optimizing the frequency response characteristics of filter by controlling ripples in passband and stopband region using FPA in one step. This paper presents an improved design of minimal power multiplierless finite impulse response (FIR) by using flower pollination algorithm (FPA) and newly proposed hybrid common sub-expression elimination (CSE) algorithm. The hardware implementation allows validation of the proposed techniques for practical filtering applications by considering real time operation parameters. In addition to the simulation results, the designed filters have been implemented in hardware using Xilinx-xc7vx330t-3ffg1157 (Virtex-7) field programmable gate array. The proposed variants of ABC are found to outperform other non-convex algorithms in achieving the desired specifications. The applicability of the proposed approach has been evaluated by comparing its response with conventional reported filter design techniques. artificial bee colony (ABC) algorithm for design of FIR filters. The present work proposes two modified versions of a recently developed evolutionary technique i.e. Evolutionary algorithms have been found to be very effective for FIR filter design because of the non-linear, non-differentiable and non-convex nature of the associated optimisation problem. The various algorithms proposed for FIR filter design aim at meeting a set of desired specifications in the frequency domain. Optimisation based design of finite impulse response (FIR) filters has been an active area of research for quite some time.
