High speed multiplier using vedic mathematicseSAT Journals
Abstract
The digital signal processing in today’s time need high speed computation. The basic building block of signal processing in
Communication, Biomedical signal processing, and Image processing remains Fast Fourier Transform (FFT). FFT computation
involves multiplications and additions. Speed of the DSP processor mainly depends on the speed of the multiplier. Time delay, power
dissipation and the silicon chip area. These are the most important parameters for the fast growing technology. The conventional
multiplication method requires more time and area and hence more power dissipation. In this paper an ancient Vedic multiplication
method called “Urdhva Triyakbhyam” is implemented. It is a method based on 16 sutras of Vedic mathematics. Vedic Mathematics
reduces the number of operations to be carried out compared to the conventional method. The code description is simulated and
synthesized using FPGA device Spartan XC3S400-PQ208.

Abstract: With the advent of new technology in the fields of VLSI and communication, there is also an ever growing demand for high speed processing and low area design. It is also a well known fact that the multiplier unit forms an integral part of processor design. Due to this regard, high speed multiplier architectures become the need of the day. In this paper, we introduce a novel architecture to perform high speed multiplication using ancient Vedic maths techniques. A new high speed approach utilizing 4:2 compressors and novel 7:2 compressors for addition has also been incorporated in the same and has been explored. Upon comparison, the compressor based multiplier introduced in this paper, is almost two times faster than the popular methods of multiplication. With regards to area, a 1% reduction is seen.

This paper anticipated the design of a novel Vedic Multiplier using the techniques of Ancient Indian
Vedic Mathematics that have been modified to improve performance. A high speed processor depends greatly
on the multiplier as it is one of the key hardware blocks in most digital signal processing system as well as in
general processors. Currently the speed of the multipliers is limited by the speed of the adders used for partial
product addition. In this paper, we proposed an 8-bit multiplier using the new methodology of Vedic
Mathematics called as Urdhva-Tiryagbhyam sutra which is used for generating the partial products. The partial
product addition in Vedic multiplier is realized using carry-skip technique. This paper depicts the design of an
efficient 8×8 binary arithmetic multiplier by using Vedic Mathematics. From various multiplication techniques,
Urdhva-Tiryagbhyam sutra is being implemented because this sutra is applicable to all cases of algorithms for
N×N bit numbers and the minimum delay is obtained. A 4×4 Vedic Multiplier is designed using 9 –full adder

In this paper, we present a novel fixed-point 32-bit word-width Radix-2 64-point FFT processor. The 64-point FFT is realized by decomposing it into a two-dimensional structure of 8-point FFTs. This approach reduces the number of required complex multiplications compared to the conventional radix-2 64-point FFT algorithm. The complex multiplication operations are realized using shift-and-add operations. Thus, the processor does not use a two-input digital multiplier. It also does not need any RAM or ROM for internal storage of coefficients. The Fast Fourier Transform (FFT) is one of the rudimentary operations in field of digital signal, image processing and FFT processor is a critical block in all multicarrier systems used primarily in the mobile environment. Fast Fourier transform (FFT) is an efficient implementation of the discrete Fourier transform (DFT). FFT blocks are complex to implement and it consumes more resources. So, a efficient technique used here in which FFT is implemented in such a way that it consumes very less resources. This module of 64-point FFT is designed using VHDL programming language. In this work, a pure VHDL design, integrated with some intellectual property (IP) blocks and simulation, synthesis and implementation XILINX ISE 13.2 software is used.

Implementation of 16 x16 bit multiplication algorithm by using vedic mathemat...eSAT Journals
Abstract Multiplication is one of the important operation in digital signal processors. The speed of processor depends on the hardware architecture, delay and power. Previously implemented Booths algorithm is not very competent in terms of delay and hardware complexity, therefore we have implemented multiplication algorithm which is efficient over booths algorithm. For multiplication, as number of bit increases the respective delay increases. For efficient processors, delay should be minimum, to avoid increase in delay we require minimum hardware architecture for the processor and Vedic multiplier has minimum hardware architecture. In this paper we have explained 16 bit ‘Urdhva Tiryagbhyam’ Vedic Multiplier and Booth Multiplier and compared on the various parameters such as speed, delay, hardware complexity. These algorithms are executed in VHDL language by using model sim and synthesis is done in Xilinx software. Spartan 3 family FPGA development board is used for hardware implementation of these algorithms. Keywords: Urdhva Tiryagbhyam, Booth, Vedic Multiplier, Spartan 3
Multipliers play an important role in today’s digital signal processing (DSP) and various other
applications. 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.

As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Abstract : A high speed processor depends greatly on the multiplier as it is one of the key hardware blocks in
most digital signal processing systems as well as in general processors. This paper presents a high speed (8x8)
modified booth multiplier which is quite different from the conventional booth multiplier. The most significant
aspect of the proposed method is that, the developed multiplier is based on Vertical and Crosswise structure of
Ancient Indian Vedic Mathematics. It generates all partial products and their sum in one step. This also gives
chances for modular design where smaller block can be used to design the bigger one. So the design complexity
gets reduced for inputs of larger number of bits and modularity gets increased. The proposed booth multiplier
using Vedic mathematics is coded in VHDL (Very High Speed Integrated Circuit Hardware Description
Language) and simulated using XilinxISE12.1. Finally the results are compared with conventional booth
multiplier to show the significant improvement in its efficiency in terms of path delay (speed). The path delay
has reduced by 44.35 % compared to the conventional booth multiplier path delay.

I. Introduction
Multiplication is a fundamental function in arithmetic operations. Arithmetic Functions are currently
implemented in many Digital Signal Processing (DSP) applications such as convolution, Fast Fourier Transform
(FFT), filtering and in microprocessors in its arithmetic and logic unit. One of the key arithmetic operations in
such applications is multiplication and the development of fast multiplier circuit has been a subject of interest
over decades. Hence reducing the time delay and power consumption are very essential requirements for many
applications. In many DSP algorithms, the multiplier lies in the critical delay path and ultimately determines the
performance of algorithm [1].
The speed of multiplication operation is of great importance in DSP as well as in general processor. In
the past multiplication was implemented generally with a sequence of addition, subtraction and shift operations.
There have been many algorithm proposals in literature to perform multiplication, each offering different
advantages and having tradeoff in terms of speed, circuit complexity, area and power consumption. Array
multipliers, Booth Multiplier are some of the standard approaches used in implementation of binary multiplier.
Section 2 covers the literature survey. Conventional Booth multiplier has been explained briefly in
section 3. Section 4 covers Booth multiplier using Vedic mathematics. The results have been discussed in
section 5. Conclusion has been given in section 6.
II. Literature Survey
The Urdhva Tiryakbhyam-Vedic method for multiplication strikes a difference in the actual process of
multiplication itself. It enables parallel generation of intermed Urdhvaiate products, eliminates unwanted
multiplication steps with zeros and scale to higher bit levels using Karatsuba algorithm with
processors(compatibility to different data types). This sutra is used to build a high speed power efficient
multiplier in the coprocessor [2]. Digital signal processors (DSPs) are very important in various engineering
disciplines. Fast multiplication is very important in DSPs for convolution, Fourier transforms etc. Among the
various methods of multiplications in Vedic mathematics, Urdhva tiryakbhyam is discussed in detail [2]. The
vedic based multiplier is compared with binary multiplier (partial products method).Multiplier based on Vedic
Mathematics is one of the fast and low power multiplier. Employing this technique in the computation
algorithms will reduce the complexity, execution time, power etc. [3]. SUMBE multiplier [4], the requirement
of the modern computer system is a dedicated and very high speed unique multiplier unit for signed and
unsigned numbers. Since signed and unsigned multiplication operation is performed by the same multiplier unit
the required hardware and the chip area reduces and this in turn reduces power dissipation and cost of a system.
A new high speed approach utilizing 4:2 compressors and novel 7:2 compressors for addition has also been
incorporated in the same and has been explored [5]. Upon comparison, the compressor based multiplier has been
introduced in this paper, is almost two times faster than the popular methods of multiplication.
This paper proposes a design of high speed Booth multiplier using the technique of Vedic mathematics.
In this multiplier, the basic multiplication is performed using one of the techniques of Vedic Mathematics. The

Vedic technique, results in a high speed multiplier. Vedic Mathematics is based on 16 sutras, out of which we
are using "Urdhva Tiryakbhyam" sutra. In this technique intermediate products are generated in parallel that
makes multiplication faster. The proposed multiplier is coded in VHDL (Very High Speed Integrated Circuits
Hardware Description Language) and simulated using Xilinx ISE 12.1 tool. Finally the results are compared
with 8-bit Booth Multiplier to show the significant improvement in its efficiency in terms of path delay (speed).
III. Booth Multiplier
Booth algorithm gives a procedure for multiplying binary integers in signed 2's complement
representation. It operates on the fact that strings of 0's in the multiplier require no addition but just shifting and
a string of 1's in the multiplier from bit weight 2k to weight 2m can be treated as (2K+1-2m). It consists of four
registers X, Y, E and Z. Register X and E are initially set to 0. If the two bits are same (11 or 00), then all the
bits of X, Z and E registers are shifted to right 1-bit without addition or subtraction. If the two bits differ, then
the multiplicand is added to or subtracted from the X register, depending on the status of bits. After addition or
subtraction right shift occurs such that the left most bit of X (Xn–1) is not only shifted into (Xn-2), but also
remains in (Xn-1). This is required to preserve the sign of the number in X and Z.
IV. Modified Booth Multiplier
Our proposed 8-bit booth multiplier is based upon Vedic mathematics. In this Booth multiplier has
been used for the multiplication purpose according to the Urdhva Tiryakbhyam sutra. The approach is different
from a number of approaches that have been used to realize multipliers.
4.1. Urdhva Tiryakbhyam Sutra (Vedic Algorithm)
The multiplier can be designed based on the “Urdhva Tiryakbhyam” sutra (algorithm). These Sutras
have been traditionally used for the multiplication of two numbers in the binary number system. In this work,
the same ideas have been implemented to the decimal number system to make the proposed algorithm
compatible with the digital hardware. It is a general multiplication formula applicable to all cases of
multiplication. It literally means “Vertically and Crosswise”. It is based on a novel concept through which the
generation of all partial products can be done with the concurrent addition of these partial products. The
algorithm can be generalized for (n x n) bit number. Since the partial products and their sums are calculated in
parallel and the multiplier is independent of the clock frequency of the processor.
4.2. Vedic Multiplier for (8x8) Bit Module
The (8x8) bit Vedic multiplier module can be easily implemented by using four (4x4) bit Vedic
multiplier modules. Let’s analyze (8x8) multiplications, say A= (A7 A6 A5 A4 A3 A2 A1 A0) and B= (B7 B6
B5B4 B3 B2 B1B0). The output line for the multiplication result will be of 16 bits as (S15 S14 S13S12 S11 S10
S9 S8 S7 S6S5S4 S3 S2 S1 S0). Let’s divide A and B into two parts, say the 8 bit multiplicand A can be
decomposed into pair of 4 bits (AH-AL). Similarly multiplicand B can be decomposed into (BH-BL). The 16 bit
product can be written as: P = A x B = (AH-AL) x (BH-BL) = AH x BH + (AH x BL + AL x BH) + (AL x BL).
Using the fundamentals of Vedic multiplication, taking four bits at a time and using 4 bit multiplier block we
can perform the multiplication. The outputs of (4x4) bit multipliers are added accordingly to obtain the final
product.
4.2.1. The Steps Followed In Proposed Multiplier
1. Inputs to the proposed multipliers are two 8 bit binary numbers.
2. These binary numbers are unpacked by using binary to BCD code.
3. Multiplication is done according to Urdhva Tiryakbhyam sutra.
4. Multiply the unpacked number by calling the Booth multiplier.
5. Unpack the first step multiplication result to separate sum and carry. Sum is the LSB bit of the final result
and carry is added to the next multiplication result.
6. Continue the previous step for step 2 and 3 according to Urdhva Tiryakbhyam sutra.
7. Finally the results are stored.

multiplier has the greatest advantage as compared to conventional Booth multiplier in terms of execution time
which is as shown in figure 3.

(Algorithm)” is presented in this paper. It gives the method of hierarchical multiplier design and indicates that
computational advantages offered by Vedic methods. The path delay for proposed (8x8) bit proposed multiplier
