In this paper, the authors propose a high speed carry select adder by replacing ripple carry adders with Beaumont-Smith adders. Adders are the basic building blocks in digital integrated circuit based designs. Ripple Carry Adders (RCAs) are usually preferred for addition of two multi-bit numbers as these RCAs offer fast design time among all types of adders. However, RCAs are slowest adders as every full adder must wait till the carry is generated from previous full adder.
