Parallel prefix adder is one of the fastest types of adder that had been created and developed. There are two types of parallel prefix adders are present. The Brent-Kung and Kogge-Stone adders. This paper involves an investigation of the performance of the Kogge-Stone adder in terms of computational power and delay. The investigation and comparison for Kogge-Stone adder was conducted for 8, 16, 32, 64 and 128-bits size. By using the Xilinx 10.1 software, the design for the Kogge-Stone adder was developed.
