1.Introduction
Multipliers plays the major role in today’s digital processing technology and various other applications. With advances in technology, many researches have tried and are trying to design multipliers which offers the following design targets such as- speed, power consumptions, regularity of layout and hence less area or even combination of them in one multiplier and making them suitable for high speed, low power, and compact VLSI design. Vedic Mathematics is used to reduce the delay and to give high speed multiplier.
2. Vedic Multiplication
2.1 Vedic Algorithm Among the 16 sutras of the ancient Indian Vedic Multiplication, Urdhava Tiryakbhyam was one of the sutras that is used in this Vedic Multiplier Module design in order

Though both multiplier have the same number of multiplication, array multiplier uses some blocks like shift and add for designing higher order multiplier. Vedic Multiplier Module is designed using cadence software, as it was more effective way of building the blocks in the silicon chip.[2]
4.1 Vedic Multiplier Module Module design for 2*2 bit Module The schematic block design for 2*2 bit module was explained below Fig .1. which was build using one bit multipliers and adders. For the design of one bit adder and multiplier, two input AND gate and full adder is used respectively.[3] Fig.1 Vedic Multiplier Module block diagram for 2*2 bit
Consider a two data input each of length 2 bits; say A1 A0 and B1 B0. Therefore the output bit is of four bit long, say as C2 S2S1 S0. The block diagram for the 2*2 bit module is shown in Fig .2. In 2*2 Vedic Multiplier Module Module S0 is obtained by multiplying the terms A0 & B0 vertically. Similarly S1 is obtained by crosswise addition of A1B0 &A0B1 and carry from the previous addition during S0 . S2 bit is obtained by the vertical addition of bits A1 B1 terms with the carry generated from the previous addition S1. C2 is nothing but the carry produced from the addition of

Conclusion This paper presents a highly effectual method of Multiplier design-Urdhva Triyakbhyam based on the Vedic Multiplier Module method and it shows the computational advantage over other methods and hence delay calculated using this method is found to be more efficient than other conventional method .
7. Future scope Instead of Carry Look ahead adder other multipliers can be used and the work can be extended by using this multiplier in the alu, accumulator unit design and compare the result with the existing design.

Abstract: This paper gives an insight into the Mathematics used by the American Indians. The history of American Indians and how they incorporated mathematics into their lives is scarce. However from the information retrieved by Archeologists, we have an idea of the type of mathematics that was used by American Indians.
...t, context switch and effects of various history register lengths- due to the increasing interference in the branch history the IHRT scheme performs the best and according to the simulations, it is evident that increasing the history register length often improves the prediction accuracy and effect of context switch- uses the BHT to keep track of branch history, the table needs to be flushed during a context switch are portrayed. On comparison, best predictors gave 94.4% accuracy whereas two-level predictors pushed it to 97%, the other 3% was still substantial miss rate and current version of simple scalar gives 98.8% hit rate.
Michael Guillen, the author of Five Equations that Changed the World, choose five famous mathematician to describe. Each of these mathematicians came up with a significant formula that deals with Physics. One could argue that others could be added to the list but there is no question that these are certainly all contenders for the top five. The book is divided into five sections, one for each of the mathematicians. Each section then has five parts, the prologue, the Veni, the Vidi, the Vici, and the epilogue. The Veni talks about the scientists as a person and their personal life. The Vidi talks about the history of the subject that the scientist talks about. The Vici talks about how the mathematician came up with their most famous formula.

This report presents the implementation of a Clock element and the use of the seven segment display on the Altera DE2-115 board. This experimentation with the clock and display are valuable since they are a precursor to future labs to come. In order to make these items work it required the use or Verilog code, which was given for parts 1, 2, and 3.
During the time of economic crisis starting around 2010 different rationalities have been taken to try and continue economic growth while maintaining a stable government system that is helping and not hurting. When examining government spending and how it affects the growth of the Gross Domestic Product (GDP) there seems to be disagreements on if it was helping or damaging the prospective growth that could be made. By using the Multiplier Effect the government can estimate how to adjust their government spending and how it effects the spending of the consumer, investments and spending of country’s exports.
» Part 1 Logarithms initially originated in an early form along with logarithm tables published by the Augustinian Monk Michael Stifel when he published ’Arithmetica integra’ in 1544. In the same publication, Stifel also became the first person to use the word ‘exponent’ and the first to indicate multiplication without the use of a symbol. In addition to mathematical findings, he also later anonymously published his prediction that at 8:00am on the 19th of October 1533, the world would end and it would be judgement day. However the Scottish astronomer, physicist, mathematician and astrologer John Napier is more famously known as the person who discovered them due to his work in 1614 called ‘Mirifici Logarithmorum Canonis Descriptio’.
And also the appendix to the Vedic hymn. Vedanta can also be secondhand as a noun to explain one who has learned all four of the earliest Vedas. The four Vedas are Rigveda, Yajurveda, Samaveda and Atharvaveda. In the former writings Sanskrit Vedanta clearly mentioned the Upanishads which is the most theoretical and philosophical of the Vedic texts. Still in the medieval age of Hindusim, the word Vedanta came to close to the school of philosophy that explained the Upanishads.
In the past few decades, one field of engineering in particular has stood out in terms of development and commercialisation; and that is electronics and computation. In 1965, when Moore’s Law was first established (Gordon E. Moore, 1965: "Cramming more components onto integrated circuits"), it was stated that the number of transistors (an electronic component according to which the processing and memory capabilities of a microchip is measured) would double every 2 years. This prediction held true even when man ushered in the new millennium. We have gone from computers that could perform one calculation in one second to a super-computer (the one at Oak Ridge National Lab) that can perform 1 quadrillion (1015) mathematical calculations per second. Thus, it is only obvious that this field would also have s...
It was in the Town High School that Ramanujan came across a mathematics book by G. S. Carr called Synopsis of Elementary Results in Pure Mathematics. Ramanujan used this to teach himself mathematics. The book contained theorems, formulas and short proofs. It also contained an index to papers on pure mathematics.

The history of math has become an important study, from ancient to modern times it has been fundamental to advances in science, engineering, and philosophy. Mathematics started with counting. In Babylonia mathematics developed from 2000B.C. A place value notation system had evolved over a lengthy time with a number base of 60. Number problems were studied from at least 1700B.C. Systems of linear equations were studied in the context of solving number problems.
To improve the energy efficiency and performance a push-pull D flip flop and push pull isolation D flip flop are suggested. Among the five DFF’s compared, the push–pull isolation circuit is found to be the fastest with the best energy efficiency. To improve performance of a conventional DFF, an inverter and transmission gate are added between outputs of master and slave latches to accomplish a push–pull effect at the slave latch, i.e., between the input and output nodes of the output inverter which will be driven to opposite logic values during switching. This adds four MOSFET’s, but reduces the clock-to-output delay from 2 gates in a conventional D flip flop to one gate. To optimize the push–pull D flip flop for energy usage, two p-MOSFETS are then added to isolate the feedback
