BCD binary numbers represent Decimal digits 0 to 9. A 4-bit BCD code is used torepresent the ten numbers 0 to 9. Since the 4-bit Code allows 16 possibilities, therefore thefirst 10 4-bit combinations are considered to be valid BCD combinations. The latter sixcombinations are invalid and do not occur.BCD Code has applications in Decimal Number display Systems such as Counters andDigital Clocks. BCD Numbers can be added together using BCD Addition. BCD Addition issimilar to normal Binary Addition except for the case when sum of two BCD digits exc ....etc

Introduction
I.a. Objectives
In this experiment, parallel adders, subtractors and complementors will be
designed and investigated. In the first and second parts of the experiment you will
implement your circuits using ICs and connecting them on the breadboard. In the
rest of the experiment, you will use Quartus 14.1 software and FPGA to
implement the circuits. In this experiment, you need to download your designs to
the FPGA and check the results by physical means, i.e., using LEDs and
oscilloscope. Another objective of this experiment ....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

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
