Abstract—Adder is one among the basic arithmetic operates. Currently implementing a high speed VLSI style could be an important topic and as adders are utilized in various fields of applications, coming up with a high speed adder is one among the necessary facets. In this paper we designed and enforced a high speed KoggeStone parallel prefix adder of 8, 16, 32 and 64 bit to be meted out and compared with Carry Look Ahead adder (CLA) and Carry Skip Adder (CSA) and also pointed out the potency of KoggeStone adder with relevance delay victimization using Xilinx ISE 14.7.

Index Terms—:64 bit high speed adder, KoggeStone adder, CLA, CSA
