Abstract

Adders form important parts of any digital circuits. Adders are much used in all integrated digital circuits because any process involving multiplication and any binary functions use adders in their processes. Adders are not only necessary for addition, but it also needs for other parameter such as subtraction, multiplication and division. In this paper we have proposed both kogge stone adder and carry select adder. The proposed adder is synthesized using Spartan 3s400-tq144. A comparative study of delay of kogge stone adder and carry select adder were analyzed and shown that delay has been reduced in kogge stone adder compared to that of carry select adder.
