1.1 INTRODUCTION

Multipliers play a key role in many high performance systems. As the technology advances, the demand of high- speed digital systems increases or we can say the demand of high speed multiplier increases because the multiplier is a main component in every digital system. Multipliers are used as small blocks in large digital systems like FIR filters, microprocessors, digital signal processors, communication systems etc. So to find performance of a large digital system is measured by the performance of the multiplier because the multiplier is mainly the slowest element in the large systems; consequently multiplication dominates the execution time of most DSP algorithms, so a high speed multiplier is always required. As compared to other operations in an ALU, the multiplier also uses more power. Thus scientists have always been trying to design a multiplier which utilizes less power, time and area and increases speed. Multiplication is such a mathematical operation in which a number i.e. multiplicand is added to itself a given number of times as indicated by another number i.e. multiplier to form a result.

A digital circuit used to multiply two numbers is called a multiplier. Multiplication, as in mathematics, consists of shifting and adding the partial products. The same concept is used here in digital multipliers. For unsigned number multiplication, AND gates are utilized for*…show more content…*

The representation in which digits after and before the decimal is fixed is called fixed point number representation. But the decimal point can float in floating point representation, hence given the name floating point. To represent extremely large and small values like distance between sun and earth or mass of electron, floating point numbers are used. To achieve better accuracy and larger range floating point representation is used although it is slower than fixed point

The influx of demand created by the government’s spending creates a need for higher output, increasing job openings which in turn decreases unemployment, thus creating more income. This wealth can then be spent within the economy, furthering the demand for higher output in a cycle known as the “Multiplier” Effect. The multiplier effect is known to snowball, continuing to increase GDP
