Threshold logic parallel counters for 32-bit multipliers

Abstract

In recent years, there has been renewed interest in Threshold Logic (TL), mainly as a result of the development of a number of successful implementations of TL gates in silicon. Threshold Logic enables, in some instances, the design of digital integrated circuits with a significantly reduced transistor count and area. This paper addresses the important problem of designing technologically feasible parallel (m,n) counters for using TL for binary multiplication. A number of counter design techniques are reviewed and some novel parallel counter designs are presented that allow the design of area efficient 32-bit multiplier partial product reduction circuits.
