ABSTRACT:
A recursive divide and conquer strategy is applied to the structure of carry select adders. This adder is partitioned into two components, each computing the sums of their inputs with and without carry in, and each component is then recursively partitioned further. The two components are combined by selecting the appropriate part of the more significant sum using the carries of the less significant component.
