Abstract
In this work we propose a switching activity model for single adder multipliers. This correspond to the case where a signal is added to a shifted version of itself, which is a common part in multiple constant multiplication (MCM). Hence, the proposed model is suitable to be used in power consumption aware MCM algorithms. The model is shown to agree well with simulations, and for the studied test cases a maximum error of 0.26% is obtained.
