Performance Analysis of 64-Bit Carry Look Ahead Adder
Daljit Kaur, Ana Monga · 2014
Abstract- Adders are used in various field of applications such as in digital electronics, VLSI (very large scale integration technology), DSP (digital signal processing), micro processors etc. In digital electronics adder is a digital circuit that is used to carry out addition of two numbers. In processor adder is the fundamental unit use to calculate the address, table indices. In VLSI it acts as the basic building block. In digital signal processing it is used in FIR, IIR filter. Today designing an adder is not an issue main prominence is on designing an adder having less delay, reduced chip area and consumes less power. In this paper 64-bit CLA is discussed and simulation results for 32bit and 64bit CLA has been exposed. The purposed design shows the Performance parameter chip area and delay in results. This adder is implemented using VHDL.
