Abstract

In this paper, the logarithmic number system (LNS) is exploited to save power. The equivalence of an LNS to a linear fixed-point system is initially explored and a related theorem is introduced. Then, activity is studied for both uniform, and Gaussian correlated input distributions. LNS is shown to reduce the average bit assertion probability by more than 60%, in certain cases, over an equivalent linear representation. The impact of LNS to power dissipation through architecture simplification is also discussed.
