Adders in Vlsi are basic components for an ALU . There are N number of adders each with their own advantages & disadvantages. When two numbers are to be added and if each of them is of N bits than we can add them in Two different ways :
Serial
Parallel

In serial addition the LSB's are added first than the carry created are propagated to the next higher bits. Whereas in parallel addition every it added in parallel without waiting for carry and different algorithms are used to compensate for the carry. ....etc

free vhdl code error tolerant adder

In conventional digital VLSI design, one usually assumes that a usable circuit/system should always provide definite and accurate results. But in fact,
such perfect operations are seldom needed in our nondigital worldly experiences. The world accepts analog computation, which generates good
enough results rather than totally accurate results (Breuer, 2005). The data processed by many digital systems may already contain errors.
In many applications, such as a communication system, the analog signal comin ....etc

verilog or vhdl code for low power error tolerant adder

Abstract: Problem statement: In modern VLSI technology, the occurrence of all kinds of errors has become inevitable. By adopting an emerging concept in VLSI design and test, Error Tolerance (ET), a novel Error-Tolerant Adder (ETA) is proposed. The ETA is able to ease the strict restriction on accuracy and at the same time achieve tremendous improvements in both the power consumption and speed performance. When compared to its conventional counterparts, the proposed ETA is able to attain i ....etc

Abstract

In this study, we had proposed architecture for high speed Truncation Adder Algorithm. In modern VLSI technology, the occurrence of all kinds of errors has become inevitable. By adopting an emerging concept in VLSI design and test, error tolerance (ET), a novel error-tolerant adder (ETA) is proposed. The ETA is able to ease the strict restriction on accuracy, and at the same time achieve tremendous improvements in both the power consumption and speed performance. When compared to its conventional counterparts, the proposed ETA is abl ....etc

Kogge-Stone adder Verilog code
KOGGE-STONE ADDER:

The KoggeStone has low logical depth, high number of nodes and minimum ventilation. While a high count of nodes implies a larger area, low logical depth and minimum fanout allow for faster performance
There are mainly three computational stages in KoggeStone Adder. They are:
1. Preprocessing
2. Carry the generation network
3. Post Processing

Pre-processing stage:
Preprocessing is the first stage in which the generation and propagation signals of all input pairs of signals A an ....etc

to construct adder subtractor using ic 7483 and to perform 4 bit adder subtractor

Introduction

To be able to perform arithmetic, you must first be familiar with numbers. Therefore, although we give a few helping examples, this article is not about binary numerals.

The main interactive circuit at the top of this page is an arithmetic circuit capable of performing both addition and subtraction on any two 4-bit binary numbers. The circuit has a Mode switch that allows you to choose between adding (M=0) and subtracting (M=1). To understand why t ....etc
