Performance Analysis of 32-Bit Array Multiplier with a Carry Save Adder and with a Carry-Look-Ahead Adder
In this paper, design of two different array multipliers are presented, one by using carry-look-ahead (CLA) logic for addition of partial product terms and another by introducing Carry Save Adder (CSA) in partial product lines. The multipliers presented in this paper were all modeled using VHDL (Very High Speed Integration Hardware Description Language) for 32-bit unsigned data. The comparison ...
متن کاملPerformance Analysis of Different Bit Carry Look Ahead Adder Using VHDL Environment
Adders are some of the most critical data path circuits requiring considerable design effort in order to squeeze out as much performance gain as possible. Various adder structures can be used to execute addition such as serial and parallel structures and most of researches have done research on the design of high-speed, low-area, or lowpower adders. Adders like ripple carry adder, carry select ...
متن کاملDesign and Implementation of Low Power 8-bit Carry-look Ahead Adder Using Static CMOS Logic and Adiabatic Logic
Addition forms the basic structure for many processing operations like counting, multiplication, filtering etc. Adder circuits that add two binary numbers are of great interest for many designers. The simplest approach to design an adder is to implement gates to yield the required logic function. Carry-look ahead adder is a major functional block in arithmetic logic unit due to its high speed o...
متن کاملDesign Consideration of Dual Threshold Logic for High Performance and Ultralow Power Carry Look-Ahead Adder
This paper presents the design of high performance and ultralow power 8-bit carry-look-ahead adder circuits using two-phase modified dual-threshold voltage (dual-VT) domino logic method with the feed through logic concept. The proposed concepts are provides lower delay and dynamic power consumption; due to these two advantages it perform better in high fan-out and high switching frequencies. Th...
متن کاملA Standard Cell Based Synchronous Dual-Bit Adder with Embedded Carry Look-Ahead
A novel synchronous dual-bit adder design, realized using the elements of commercial standard cell libraries is presented in this article. The adder embeds two-bit carry look-ahead generator functionality and is realized using simple and compound gates of the standard cell library. The performance of the proposed dualbit adder design is evaluated and compared vis-à-vis the conventional full add...
