Implementation of PPA-Brent Kung Adder For Computing Application

Abstract

In this paper, the implementation of residue number system reverse converters based on Brent Kung adders is analyzed. The parallel prefix adder provides high speed and reduced delay arithmetic operations but it is not widely used since it suffers from high power consumption. Hence, a Brent Kung adder component is presented to perform fast modulo addition in Residue Number System reverse conversion. The proposed components are not only results in fast arithmetic operation and it also highly reduced the hardware complexity since it requires fewer amount of logic elements. In this work, the proposed components are implemented in different module sets reverse converter designs and the performances are compared for different values of n.
