Abstract

The adder is a vital part of the Central Processing Unit (CPU) that can perform computational operations. It is used in digital components, mainly in the design of integrated circuits. Recent decades have seen a sharp rise in demand for mobile electronics, which has increased the need for highly efficient Very Large-Scale Integration (VLSI) structures. All operations must be computed using low-power, space-efficient designs that run faster. The Kogge-Stone adder (KSA) is an extension of the carry look-ahead adder which is used for performing fast addition in high-performance computing systems. This study compares the latency, space, and energy used by the Kogge-Stone Adder after development and implementation in Xilinx Vivado using Verilog to those of the Ripple Carry Adder (RCA) and Carry Lookahead Adder (CLA). The results show that the KSA has a decrease in power consumption as well as improvements in high speed and area compaction when compared to the RCA and CLA.

Keywords

Adder, Carry Look-Ahead Adder (CLA), Kogge-Stone Adder (KSA), Ripple Carry Adder (RCA).
