Design of IIR Filter Using Wallace Tree Multiplier

Abstract

A multiplier is the most complex and important block in the design of filter. In this paper, designing of IIR filter is carried out using Wallace tree multiplier which is compared with the other designing methods of IIR filter. MATLAB FDA toolbox is used to calculate the filter coefficients and Xilinx Spartan 3E XC3S500E is used for the realization of the design. Power calculation is carried by Vivado 2016.2. Based on the simulation results, IIR filter design using Wallace tree multiplier turns out to be more efficient in terms of the speed performance as compared to other IIR filter design methods.
