Recently, the increased use of portable devices, has driven the research world to design systems with low power-consumption and high throughput. Vedic multiplier provides least delay even in complex multiplications when compared to other conventional multipliers. In this paper, a 64-bit multiplier is created using the Urdhava Tiryakbhyam sutra in Vedic mathematics. The design of this 64-bit multiplier is implemented in five different ways with the pipelining concept applied at different stages of adder complexities. The different architectures show different delay and power consumption. It is noticed that as complexity of adders in the multipliers reduce, the systems show improved speed and least hardware utilization. The architecture designed using 2 x 2 – bit pipelined Vedic multiplier is, then, compared with existing Vedic multipliers and conventional multipliers and shows least delay.

In recent years, there has been an increasing tendency towards designing circuits based on reversible logic, and has received much attention because of preventing internal power dissipation. In digital computing systems, multiplier circuits are one of the most fundamental and practical circuits used in the development of a wide range of hardware such as arithmetic circuits and Arithmetic Logic Unit (ALU). Vedic multiplier, which is based on Urdhva Tiryakbhayam (UT) algorithm, has many applications in circuit designing because of its high speed in performing multiplication compared to other multipliers. In Vedic multipliers, partial products are obtained through vertical and cross multiplication. In this paper, we propose four [Formula: see text] reversible Vedic multiplier blocks and use each one of them in its right place. Then, we propose a [Formula: see text] reversible Vedic multiplier using the four aforementioned multipliers. We prove that our design leads to better results in terms of quantum cost, number of constant inputs and number of garbage outputs, compared to the previous ones. We also expand our proposed design to [Formula: see text] multipliers which enable us to develop our proposed design in every dimension. Moreover, we propose a formula in order to calculate the quantum cost of our proposed [Formula: see text] reversible Vedic multiplier, which allows us to calculate the quantum cost even before designing the multiplier.

Vedic maths is an ancient mathematical theory based on 16 sutras that has a unique computation technique. We employ the fourteenth sutra, 'Urdhva Tiryakbhyam', from the 16 sutras. Multiplication can be done 'vertically and crosswise' using this sutra. The creation of a high-speed Vedic Multiplier based on ancient Indian Vedic Mathematics principles that have been tweaked to boost efficiency. Power, area, and latency are the three fundamental restrictions in modern VLSI technological advancements. Multipliers are used in high-speed arithmetic logic units, multiplier and accumulate units, and other similar applications. With the rising limits on latency, the design of faster multiplications is becoming increasingly important. Many changes are being done to improve speed. Vedic multipliers based on Vedic Mathematics are among them. Power, area, and latency are the three fundamental restrictions in modern VLSI technological advancements. CMOS (Complementary metal-oxide-semiconductor) designs take up more space and use more energy. Power dissipation causes an IC to heat up, which has a direct impact on its reliability and performance. Gate Diffusion Input (GDI) technology reduces the size, propagation delay, and power consumption of digital circuits while also lowering logic complexity as compared to traditional CMOS and existing pass transistor logic approaches. We compared a 2x2 Vedic multiplier based on the GDI and mGDI (Modified GDI) techniques in this study. In comparison to the GDI approach, the mGDI technology employs much less transistors. The Vedic multiplier is implemented in the cadence virtuoso tool, on 180nm and 90nm technology.

A high speed N × N bit multiplier architecture that supports signed and unsigned multiplication operations is proposed in this paper. This architecture incorporates the modified two's complement circuits and also N × N bit unsigned multiplier circuit. This unsigned multiplier circuit is based on decomposing the multiplier circuit into smaller-precision independent multipliers using Vedic Mathematics. These individual multipliers generate the partial products in parallel for high speed operation, which are combined by using high speed adders and parallel adder to generate the product output. The proposed architecture has regular-shape for the partial product tree that makes easy to implement. Finally, this multiplier architecture is implemented in UMC 65 nm technology for N = 8, 16 and 32 bits. The synthesis results shows that the proposed multiplier architecture improves in terms of speed and also reduces power-delay product (PDP), compared to the architectures in the literature.

Streszczenie:

A multiplier is one of the main units for digital signal processing and communication systems. In this paper, a high speed and low complexity multiplier is designed on the basis of quantum-dot cellular automata (QCA), which is considered promising nanotechnology. We focus on Vedic multiplier architectures according to Vedic mathematics from ancient Indian sculptures. In fact, an adder is an important block in the design of almost all types of multipliers and a ripple carry adder is used to design simple multiplier implementations. However, a high-speed multi-bit multiplier requires high-speed adder owing to carry propagation. Cell-interaction-based QCA adders have better improvements over conventional majority-gate-based adders. Therefore, a two-bit Vedic multiplier is proposed in QCA and it is used to implement a four-bit form of the multiplier. The proposed architecture has a lower cell count and area compared to other existing structures. Moreover, simulation results demonstrate that the proposed design is sustainable and can be used to realize complex circuit designs for QCA communication networks.

High speed and efficient multipliers are essential components in today’s computational circuits like digital signal processing, algorithms for cryptography and high performance processors. Invariably, almost all processing units will contain hardware multipliers based on some algorithm that fits the application requirement. Tremendous advances in VLSI technology over the past several years resulted in an increased need for high speed multipliers and compelled the designers to go for trade-offs among speed, power consumption and area. Amongst various methods of multiplication, Vedic multipliers are gaining ground due to their expected improvement in performance. A novel multiplier design for high speed VLSI applications using Urdhva-Tiryagbhyamsutra of Vedic Multiplication has been presented in this paper. The multiplier architecture is implemented using Verilog coding and synthesise during Cadence RTL Compiler. Physical design is implemented using Cadence Encounter RTL-to-GDSII System using standard 180nm technology. The proposed multiplier architecture is compared with the conventional multiplier and the results show significant improvement in speed and power dissipation.

Abstract: This paper proposes low-power multiplier architectures based on Vedic mathematics, which is a set of ancient Indian techniques for performing arithmetic operations. The proposed architectures use the Urdhva-Tiryagbhyam sutra from Vedic mathematics, which enables the efficient multiplication of numbers with fewer partial products. The proposed architectures have been implemented and simulated using the 45-nm CMOS technology. The simulation results demonstrate that the proposed architectures achieve significant power savings compared to conventional multipliers while maintaining reasonable area and delay. Therefore, the proposed architectures are suitable for use in low-power and high-performance applications. The Vedic multiplier consists of several sub-modules, each of which performs a specific function in the multiplication process. These submodules include the partial product generator, the multiplier, and the adder. The partial product generator generates partial products based on the input numbers and the Vedic sutras. The multiplier module then combines these partial products to create the final product. Finally, the adder module adds the product to the previous state of the circuit to generate the final result.

The 2x2, 3x2 and 3x3 MUX based multipliers are designed. The basic lower order MUX based multipliers are used to design higher order MxN multipliers with a concept of UrdhvaTiryakbyham Vedic approach. The proposed multiplier is used for image processing applications. It is observed that the device utilization and combinational delay are less in the proposed architecture compared to existing architectures.

Multipliers are the basic building blocks in various digital signal processing applications such as convolution, correlation, and filters. However, conventional array multipliers, vedic multipliers were resulted in higher area, power, delay consumptions. Therefore, this work is focused on design and implementation of variable width Radix-4 booth multiplier using Data Scaling Technology (DST). The radix-4 modified booth encoding was used in the production of these incomplete items. In accumulation, the bits of the fractional products are added in a parallel manner with decreased stages using a multi-stage carry propagation adder (MSCPA). The simulation demonstrated that the suggested DST-Radix-4 booth multiplier (DST-R4BM) resulted in higher performance in comparison to traditional multiplies in terms of area, delay, and power.

Digital systems which are more effective are necessary due to the enormous growth in the technology. So, we go for multipliers which are playing a key role in each and every digital domain device. Also, designing a multiplier with high speeds to perform ALU operations is an important aspect in digital signal processing. These operations are used for DFT, convolution etc. Hence, professionals in DSP domain are trying to develop innovative algorithms and hardware implementation. It is very essential to employ a multiplier which is more effective. They are many standard algorithms that are existing to reduce the area and time needed for execution. Vedic era described algorithms in vedic mathematics that supply an efficiency which are of high level. They provide 16 sutras for the operation of multiplication. Here, we discuss about urdhva tiryakbhyam algorithm for multiplication operation. Therefore, vedic algoritm provides better efficiency in comparison to that of conventional multipliers.

Streszczenie:

Nowadays, the requirement for very high-speed operations in processors constantly increases. Multiplication is a crucial operation in high power-consuming processes such as image and signal processing. The main characteristics of a multiplier are good accuracy, speed, reduction in area, and little power consumption. Speed plays a major role in multiplication operations, and an increase in speed can be obtained by reducing the number of steps involved in the computation process. Since a multiplier has the largest delay among the basic blocks in a digital system, the critical path is determined by it. Furthermore, the multiplier consumes more area and dissipates more power. Hence, designing multipliers that offer high speed, lower power consumption, less area, or a combination of them is of prime concern. Hence, an attempt is made in this paper to achieve the above design metrics using a Spurious Power Suppression Technique (SPST) adder. A resource-efficient SPST-based Vedic multiplier is developed and implemented using Artix 7 FPGA and is finally compared with the ripple carry adder-based Vedic multiplier.

Convolution is an algorithm which is mainly used in video, audio and image processing. Convolution calculation is simple in steps however it consumes a lot of memory as well as power in the computational process. It is a mathematical algorithm which is also used in the applications like filtering, edge detection, de-noising, compression etc., as it can be exploit computational power. In this paper, we implemented the speed of discrete linear convolution using robust Vedic multiplier which is one of the fastest multipliers with two finite-length sequences. By implementing convolution with Vedic multiplier power, area and delay are reduced. This implementation process can be realized by simplifying the convolution building block.

Urdhva triyagbhyam is a vertical and crosswise approach to discover product of two numbers. Multiplication is an essential quintessential feature in arithmetic logic operation. Computational overall performance of a DSP device is limited via its multiplication overall performance and since, multiplication dominates the execution time of most DSP algorithms. Multiplication is one of the simple arithmetic operations and it requires extensively extra hardware assets and processing time than addition and subtraction. Our work is to compare different bit Vedic multiplier structure using carry look ahead adder technique. Keywords: Carry Look Ahead Adder, Urdhva Trigbhyam, DSP algorithms, Vedic Multiplier

The Vedic multiplier is derived from the ancient mathematics called Vedic mathematics .The ancient mathematics has different sutras in that we use Urdhva Tiryagbhyam sutra which means clock wise and vertically . As we know that binary multiplication is not possible so that instead we use binary addition or subtraction instead of it. The key process for the multiplication is the speed of the processor. The fastest mode of multiplication is the Vedic multiplier. In this paper we want to show the delay and utilization of components available for the multiplier by executing the code. The comparison of delay from some papers was also proposed in this paper. The research is going on the Vedic mathematics to overcome the problems on the conventional mathematics. In future Vedic multiplier plays an important role in the DSP (Digital Signal Processing).As it is the fastest and efficient mode of operation. In this paper I am calculating the bit wise delay up to 32-bit. The whole analysis was done in Xilinx. The ISM wave forms for every bit up to 32-bit was to be obtained. The utilization, used, available, utilized analysis was also taken. The whole process was done in XILINX software.

With an ever growing demand for low-power devices, it is a general trend to search for ways to reduce the power consumption of a system. Multipliers are an important requirement in applications linked to Digital Signal Processing, Communication Systems, Optical Computing, Nanotechnology, Low-Power Very Large Scale Integration and Quantum Computing. Conventional mathematics makes multiplication a very long and time consuming process. The use of Vedic mathematics has led to great reduction in the time required for such calculations. The excessive use of Urdhava Tiryakbhyam sutra in multiplication surely proves its effectiveness and simplicity in this domain. This sutra supports the process of pipelining, a method employed in reduction of the power used by a system. Reversible logic has been gaining demand due to its low-power capabilities and is currently being used in many computing applications. The paper proposes two multiplier systems: one design employs the Urdhava Tiryakbhyam sutra along with pipelining and the second uses reversible logic gates into the first design. These proposed systems provide very less delay for result computation and low hardware utilization when compared to non-pipelined Vedic multipliers.

Abstract The performance of a microprocessor depends on the efficient multiplier as it is one of the most principal component in various digital circuits. This paper reviews optimization techniques for high speed Vedic multiplier design which is based on Urdhva Tiryakbhyam Sutra of Ancient Indian Vedic Mathematics. This particular sutra is the most efficient one as it gives minimum delay for all types of complex multiplication. Adder being the most important component in a multiplier design, using the efficient adder will enhance the performance of Vedic multiplier. During the comparison, different adder topologies like Carry Look ahead Adder, Kogge Stone Adder, Carry Skip Adder are used to compare area, delay and power. The reviewed methods are implemented on 45nanometer(nm), 90nm and 180 nm CMOS technology. The results of all the prior approaches are reviewed and an efficient method out of them has been proposed.

In any integrated chip compulsory adders are required because first they are fast and second are the less power consumption and delay. And at the same time multiplication process is also used in various applications. So as the speed of multiplier increases then the speed of processor also increases.

In any integrated chip compulsory adders are required because first they are fast and second are the less power consumption and delay. And at the same time multiplication process is also used in various applications. So as the speed of multiplier increases then the speed of processor also increases. And hence we are proposing the Vedic multiplier using these adders. Vedic multiplier is an ancient mathematics which uses mainly 16 sutras for its operation. In this project we are using “urdhva triyagbhyam” sutra to do our process.

Energy dissipation and reliability are the two important design constraints in the high performance processor design. With the advancements in the IC manufacturing and reduced feature sizes the energy dissipation increases in exponential manner at the lower technology nodes. So, there is a need to design energy-efficient and reliable circuits and systems. The reliability with temperature is also one of the major challenges in today’s smart systems as they are operated in harsh environments. Most of the works till date analyzed the reliability with respect to DC constraints. The basic operation in the high performance Digital Signal Processing (DSP) is the multiplication is used to simplify various operations like convolution, filtering and correlation. In this work, a Vedic multiplier with 4x4 size is implemented with FinFET based energy recovery Modified PFAL (MPFAL) logic at 45 nm technology node. The designed multiplier performance is analyzed and compared with our earlier work in terms of energy dissipation and delay. The results indicate a reduction of 55% in energy dissipation over ECRL based Vedic multiplier. Linear variation of power dissipation with temperature in the order of pW shows that design MPFAL Vedic muliplier is more reliable compared to CMOS multiplier.

Vedic mathematics is an old mathematics which is more effective than other mathematic procedures. Vedic maths is utilized as a part of numerous applications, for example, hypothesis of numbers, compound duplications, squaring, cubing, square root and solid shape root and so on. Absolutely there are 16 sutras and 14 sub-sutras in Vedic maths. Among those sutras, just 3 sutras and 2 sub-sutras are utilized for augmentation. Multiplier is a very important part of a microprocessor as multiplication is performed continuously in all calculative procedures. This paper is in importance of a 8-bit multiplier designed in 90 nm technology. Urdhva-Tiryakbyham is the sutra that is used for multiplication in Vedic mathematics. Actualizing the different scientific operations utilizing Vedic Mathematics causes us accomplish better speed, bring down unpredictability and higher execution.[2] The technique used is Gate Diffusion Input (GDI) which is a more refined way to design a circuit which less complex than circuits designed by other techniques.

At present, there are several pieces of research on designing and implementing new cryptographic algorithms that are lightweight and resistant to several, if not major forms of security attacks. However, some algorithms such as the International Data Encryption Algorithm (IDEA), which has been around for some time is yet to record any real threat against its functionality. To ensure its continued usage, current implementations rely on multiphase encryption where it is combined with other algorithms such as ROTation (ROT) and Data Encryption Standard (DES) for maximum security strength. Multiphase encryption implies that there is a tendency for an increase in hardware area and a reduction in overall speed. In such cases, having fast and reduced area algorithms are much desired. This paper, therefore, proposes an efficient hardware implementation of the IDEA cipher that is based on arithmetic modulo multiplication—one of the main computations of the IDEA—on a novel Vedic multiplier architecture. The increase in efficiency of the IDEA crypto architecture and the reduction in resources utilization is achieved through an enhancement of its structural architecture to utilize a fixed set of resources for all eight identical rounds of computation and the use of a proposed fast and lightweight Vedic hardware multiplier. The proposed hardware modification and resulting architecture are designed using the Xilinx ISE and Vivado tools. The architecture is synthesized using Precision Synthesis Tool (PS) and simulated using Modelsim SE 10.6d and ISIM simulation tools. The proposed IDEA cipher is 100% more efficient when designed based on the Vedic multiplier compared to existing designs. The hardware architecture is implemented on Spartan-6-FGG484 Field Programmable Gate Array (FPGA) using Verilog HDL. Verified results show that the proposed Vedic-based IDEA occupied 212 Slices with the Vedic multiplier only occupying 28 Slices out of the total 212. The proposed architecture operates at a maximum frequency of 253.3 MHz.

The fundamental and the core of all the Digital Signal Processors (DSPs) are its multipliers and the speed of the DSPs is mainly determined by the speed of its multiplier. IEEE floating point format is a standard format used in all processing elements since Binary floating point numbers multiplication is one of the basic functions used in digital signal processing (DSP) application. In this work VHDL implementation of Floating Point Multiplier using Vedic mathematics is carried out. The Urdhva Tiryakbhyam sutra (method) was selected for implementation since it is applicable to all cases of multiplication. Multiplication of two no’s using Urdhva Tiryakbhyam sutra is performed by vertically and crosswise. The feature is any multi-bit multiplication can be reduced down to single bit multiplication and addition using this method. On account of these formulas, the carry propagation from LSB to MSB is reduces due to one step generation of partial product.

Abstract: The digital signal processing and its classification applications on the energy constrained devices should be supported based on efficiency. Because such applications must perform highly complex computations especially complex multiplication processes while exhibiting tolerance for a large amount of noise and for computational errors too. So, comparing all the arithmetic computations, improving the energy efficiency of multiplication is critical. In this project, an energy efficient approximate 8-bit Vedic multiplier is proposed which gives a tradeoff between computational accuracy and energy consumption. The proposed architecture has reduced area compared to other multiplier architectures which process same number of bits. The reduced architecture area reduces the power consumption. Also, the Vedic technology adopted for the multiplication reducesthe delay further. But the approximate architecture output possesses a small amount of computational accuracy which is negligible for DSP applications.

Multiplication is an important fundamental function in arithmetic operations. Multiplication-based operations such as Multiply and Accumulate (MAC) and inner product are some of the frequently used operations in many Digital Signal Processing (DSP) applications such as convolution, Fast Fourier Transform(FFT), filtering and in microprocessors in its arithmetic and logic unit. Since multiplication dominates the execution time of most DSP algorithms, so there is a need of high speed multiplier. Higher throughput arithmetic operations are important to achieve the desired performance in many real-time signal and image processing applications. In this project, the comparative study of Vedic multiplier and Sequential multiplier is done for low power requirement and high speed. The proposed architecture is based on the Vertical and Crosswise algorithm of ancient Indian Vedic Mathematics, which increases the speed of multiplier by reducing the number of clock cycles thus achieving the greater speed of the processor or system.
