VLSI Implementation of Vedic Multiplier Using Urdhva– Tiryakbhyam Sutra in VH...
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
and a special 4-bit adder which is having reduced delay. Then 8-bit multiplier is designed using four 4-bit
multiplier and 3-ripple carry adder. Then 8×8 Vedic Multiplier is coded in VHDL, synthesized and simulated
using Xilinx ISE8.2 Software. Finally the objective of this paper lies in design of an efficient vedic multiplier
using Urdhva–Tiryakbhyam Sutra in VHDL Environment.
Latches and flip flop
This document discusses latches and flip flops, which are types of sequential logic circuits. It describes the basic components and functioning of latches like SR latches, D latches, and gated latches. For flip flops, it covers SR flip flops, D flip flops, JK flip flops, and master-slave flip flops. The key differences between latches and flip flops are that latches do not have a clock input while flip flops are edge-triggered by a clock signal. Latches and flip flops are used as basic storage elements in more complex sequential circuits and in computer components like registers and RAM.
Adder
This document summarizes different types of adders used in digital circuits. It introduces half adders, full adders, ripple carry adders, look ahead carry adders, and carry save adders. Half adders add two bits and produce a sum and carry output. Full adders add three bits. Ripple carry adders are made of cascaded full adders to add multiple bits, with each full adder inputting the carry from the previous stage. Look ahead carry adders reduce delay by calculating carry signals in parallel rather than series. Carry save adders add three bits in parallel and store the carry rather than propagating it to reduce delay.

An Optimized Implementation Of 64-Bit MAC Unit For DSP Applications Using SPST
With the rapid advances in multimedia and communication system, high capacity signal processing are in demand, so High Speed MAC are essential to improve performance of signal processing System. Multiplication occurs frequently in finite impulse response filters, fast Fourier transforms, discrete cosine transforms, convolution, and other important DSP and multimedia kernels. The objective of a good multiplier and accumulator (MAC) is to provide a physically compact, good speed and low power consuming chip. The proposed SPST separates the target designs into two parts, i.e., the most significant part and least significant part (MSP and LSP), and turns off the MSP when it does not affect the computation results to save power.In These Project I propose a high speed MAC adopting the new SPST implementing approach. This multiplier and accumulator is designed by equipping the Spurious Power Suppression Technique (SPST) on a modified Booth encoder which is controlled by a detection unit using an AND gate.
Language: Verilog.
Software:Modelsim ,Xilinx ISE

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. The design and experiments were carried out on a Xilinx Spartan 3e series of FPGA and the timing and area of the design, on the same have been calculated.

This document summarizes a research paper that proposes a new efficient design for binary number squaring using Dwandwa Yoga logic from Vedic mathematics. The design reduces carry propagation delay compared to other multiplication algorithms. It works by calculating the square based on the "duplex" property of Dwandwa Yoga, where the square is the sum of outer pair products and inner elements squared. For a 4-bit number, it computes the square in 7 parallel steps. Simulation results show the design requires fewer logic gates and less delay compared to array and Booth multipliers. The proposed algorithm improves efficiency for applications requiring low power and area.

FPGA Implementation of High Speed 8bit Vedic Multiplier using Barrel Shifter
In today’s world Vedic mathematics has
proved to be the most robust technique for arithmetic
operations. In contrast, conventional techniques for
multiplication provide significant amount of delay in hardware
implementation of n-bit multiplier. Moreover, the
combinational delay of the design degrades the performance
of the multiplier. Hardware-based multiplication mainly
depends upon architecture selection in FPGA or ASIC.
A barrel shifter is a digital circuit that can shift a data word by
a specified number of bits in one clock cycle. It can be
implemented as a sequence of multiplexers (mux.), and in
such an implementation the output of one mux is connected to
the input of the next mux in a way that depends on the shift
distance.
