Design of a 64-bit SQRT-CSLA with Reduced Area and High-Speed Applications in Low Power VLSI Circuits

Abstract

The main areas of research in VLSI system design include area, high speed, and power-efficient data route logic systems. The amount of time needed to send a carry through the adder limits the pace at which addition can occur in digital adders. One of the quickest adders, the Carry Select Adder (CSLA), is utilized by various data processing processors to carry out quick arithmetic operations. It is evident from the CSLA's structure that there is room to cut back on both the area and the delay. This work employs a straightforward and effective gate-level adjustment (in a regular structure) that significantly lowers the CSLA's area and delay. In light of this adjustment Square-Root Carry Select Adder (SQRT CSLA) designs with bit lengths of 8, 16, 32, and 64. When compared to the standard SQRT CSLA, the suggested design significantly reduces both area and latency. Xilinx ISE tool is used for Simulation and synthesis. The performance of the recommended designs in terms of delay is estimated in this study using the standard designs. The study of the findings indicates that the suggested CSLA structure outperforms the standard SQRT CSLA.
