Abstract

This paper presents a novel approach for theoretical estimation of power consumption in digital binary adders. Closed-form expressions for power consumption of four different types of binary adders - the ripple-carry adder, the Manchester adder, a multiplexor-based carry-select adder and an efficient tree-based look-ahead adder - are derived in terms of word-length and pre-computed technology-specific energy parameters. These expressions are verified to be accurate to within 1-5% by simulation using the HEAT tool.
