Abstract

This paper describes a method to improve the per- formance of higher radix SRT dividers built t?om smaller radii blocks. A new partial remainder formation (PRF) circuit for a radix 8 SRT divider is presented which improves the speed at which the next partial remainder is generated. The speed improvement is achieved with no additional cost in silicon area or power consumed. This PRF modification can be. applied to any higher radix SRT divider built from smaller overlapped blocks given the asymmetry of carry-save adders.
