The document describes a proposed low power, high speed multiplier circuit designed using a technique called New Vedic VLSI. The multiplier uses a Vedic multiplication method to generate partial products faster. An addition section with a carry look ahead adder is used to sum the partial products, providing faster operation than a ripple carry adder. Simulation results showed the proposed design consumed 41.868 μw of power over 10ns, compared to 65.4 μw for a design using a ripple carry adder, for a 23.592 μw power reduction. The high speed, low power multiplier design is suitable for applications like digital signal processors that require efficient multiplication.

An Area-efficient Montgomery Modular Multiplier for CryptosystemsIJERA Editor
RSA is one of the most widely adopted public key algorithms at present and it requires repeated modular
multiplications to accomplish the computation of modular exponentiation. A famous approach to implement
modular multiplication in hardware circuits is based on the Montgomery modular multiplication algorithm since
it has many advantages. To speed up the encryption/decryption process, many high-speed Montgomery modular
multiplication algorithms and hardware architectures employ carry-save addition. But CSA based architecture
increases the area. In this paper, in order to reduce the area of the CSA based multiplier, an area-efficient
algorithm called Double Add Reduce algorithm is introduced. Then the performance analysis of the new design
with the previous had done for comparison.

A High Speed Wallace Tree Multiplier Using Modified Booth Algorithm for Fast ...Kumar Goud
Abstract— Designing multipliers that are of high-speed, low power, and regular in layout are of substantial research interest. Speed of the multiplier can be increased by reducing the generated partial products. Many attempts have been made to reduce the number of partial products generated in a multiplication process; one of them is Wallace tree multiplier. Wallace Tree CSA structures have been used to sum the partial products in reduced time. In this paper Wallace tree construction is investigated and evaluated. Speed of traditional Wallace tree multiplier can be improved by using compressor techniques. In this paper Wallace tree is constructed by traditional method and with the help of compressor techniques such as 4:2 compressor, 5:2 compressor, 6:2 compressor, 7:2 compressor. Therefore, minimizing the number of half adders used in a multiplier reduction will reduce the complexity.

Implemenation of Vedic Multiplier Using Reversible Gates csandit
With DSP applications evolving continuously, there is continuous need for improved multipliers which are faster and power efficient. Reversible logic is a new and promising field which addresses the problem of power dissipation. It has been shown to consume zero power theoretically. Vedic mathematics techniques have always proven to be fast and efficient for solving various problems. Therefore, in this paper we implement Urdhva Tiryagbhyam algorithm using reversible logic thereby addressing two important issues – speed and power consumption of implementation of multipliers. In this work, the design of 4x4 Vedic multiplier is optimized by reducing the number of logic gates, constant inputs, and garbage outputs. This multiplier can find its application in various fields like convolution, filter applications, cryptography, and communication.
Design and Implementation of 8 Bit Multiplier Using M.G.D.I. TechniqueIJMER
In this paper we have implemented Radix 8 High Speed Low Power Binary Multiplier using
Modified Gate Diffusion Input(M.G.D.I) technique. Here we have used “Urdhva-tiryakbhyam”(
Vertically and crosswise ) Algorithm because as compared to other multiplication algorithms it shows
less computation and less complexity since it reduces the total number of partial products to half of it.
This multiplier at gate level can be design using any technique such as CMOS, PTL and TG but design
with new MGDI technique gives far better result in terms of area, switching delay and power
dissipation. The radix 8 High Speed Low Power Pipelined Multiplier is designed with MGDI technique
in DSCH 3.5 and layout generated in Microwind tool. The Simulation is done using 0.12μm technology
at 1.2 v supply voltage and results are compared with conventional CMOS technique. Simulation result
shows great improvement in terms of area, switching delay and power dissipation.
Multiplication is the most time consuming process in various signal processing operations like convolution,
circular convolution, auto-correlation and cross-correlation. With advances in technology, many researchers have
tried and are trying to design multipliers which offer either of the following- high speed, low power consumption,
regularity of layout and hence less area or even combination of them in multiplier. However area and speed are
two conflicting constraints. So improving speed results always in larger areas. So here we try to find out the best
trade off solution among the both of them. To have features like high speed and low power consumption
multipliers several algorithms have been introduced .In this paper, we describes Multipliers by using various
algorithm in VLSI technology. The Wallace Tree Multipliers are compared with existing multipliers in terms of
improvement in features like area, delay and power consumption by using different logical operation.
VLSI ARCHITECTURE OF AN 8-BIT MULTIPLIER USING VEDIC MATHEMATICS IN 180NM TEC...P singh
A Multiplier is one of the key hardware blocks in most fast processing system which requires less power dissipation. A conventional multiplier consumes more power. This paper presents a low power 8 bit Vedic Multiplier (VM) based on Vertically & Crosswise method of Vedic mathematics, a general multiplication formulae equally applicable to all cases of multiplication. It is based on generating all partial products and their sum in one step. The implementation is done using cadence Virtuoso tool. The power dissipation of 8x8 bit Vedic multiplier obtained after synthesis is compared with conventional multipliers such as Wallace tree and array multipliers and found that the proposed Vedic multiplier circuit seems to have better performance in terms of power dissipation.
EFFICIENT IMPLEMENTATION OF 16-BIT MULTIPLIER-ACCUMULATOR USING RADIX-2 MODIF...VLSICS Design
In this paper, we propose a new multiplier-and-accumulator (MAC) architecture for low power and high speed arithmetic. High speed and low power MAC units are required for applications of digital signal processing like Fast Fourier Transform, Finite Impulse Response filters, convolution etc. For improving the speed and reducing the dynamic power, there is a need to reduce the glitches (1 to 0 transition) and spikes (0 to 1 transition). Adder designed using spurious power suppression technique (SPST) avoids the unwanted glitches and spikes, thus minimizing the switching power dissipation and hence the dynamic power. Radix -2 modified booth algorithm reduces the number of partial products to half by grouping of bits from the multiplier term, which improves the speed. The proposed radix-2 modified Booth algorithm
MAC with SPST gives a factor of 5 less delay and 7% less power consumption as compared to array MAC

This paper presents the design and implementation of radix-8 booth Multiplier .The number of partial
products are reduced to n/2 in radix-4We can reduce the number of partial products even further to n/3 by
using a higher radix-8 in the multiplier encoding, thereby obtaining a simpler CSA tree .This implies less
delay and a smaller area size .Since this multiplication operation is for both signed and unsigned
numbers,cost of the system can also be reduced.

Hardware Implementation of Two’s Compliment Multiplier with Partial Product b...IJERA Editor
With the emergence of portable computing and communication systems, power consumption has become one of the major objectives during VLSI design. Furthermore, the multiplication is an essential arithmetic operation for common DSP applications, such as filtering, convolution, fast Fourier Transform (FFT) etc. To achieve high execution speed, parallel array multipliers are widely used. These multipliers tend to consume most of the power in DSP computations, and thus power-efficient multipliers are very important for the design of low-power DSP systems. This paper presents an approach to reduce power consumption of 2’s compliment multiplier design, in which switching activities are reduced through dynamic by passing of partial products.
