Multiple Valued Logic for Synthesis and Simulation of Digital CircuitsIJERA Editor
The Multiple valued logic(MVL) has increased attention in the last decades because of the possibility to represent the information with more than two discrete levels.Advancing from two-valued to four-valued logic provides a progressive approach. In new technologies, the most delay and power occurs in the connections between gates. When designing a function using MVL, we need fewer gates,which implies less number of connections, then less delay. In the existing system, the 4:1 multiplexer is designed using the MVL logic and various paramaters are analysed. In the proposed system, the idea of designing a Barrel shifter using the multiple valued logic and the parameters are all analyzed. All these designs are verified using Modelsim simulator.

POWER GATING STRUCTURE FOR REVERSIBLE PROGRAMMABLE LOGIC ARRAYecij
Throughout the world, the numbers of researchers or hardware designer struggle for the reducing of
power dissipation in low power VLSI systems. This paper presented an idea of using the power gating
structure for reducing the sub threshold leakage in the reversible system. This concept presented in the
paper is entirely new and presented in the literature of reversible logics. By using the reversible logics for

Abstract: Latest technological development in VLSI design permits more functions integrated in a single chip. Multipliers are crucially important building structures for advanced computing and as a part of digital processing system. These logic and arithmetic structures should have to be speedy as well as precise enough so that number of such circuits can be integrated along a single chip. Considering this there is advancement in IC fabrication and design is still going on. In VLSI circuit area, power and delay are the parameters which are considered as design parameters. However, there exists a trade-off amongst them for an optimal design. Multipliers have very crucial and important part in designing of microprocessors, multimedia system and digital signal processors etc. Almost 15% of total IC power is consumed by multiplication unit alone. So it becomes very important to have a well organized design in terms of performance, area and its processing speed of multipliers and same as for Booth multiplication algorithm which gives a fundamental platform for such improvements in the designing of high speed multipliers with great performance.
Booth algorithm gives such an efficient encoding scheme of the bits through first steps of the multiplication process. This work is based on configurable logic for 16-bit Booth multiplier using Radix-2 and Radix-4 Method. Booth multiplier can be configured to perform multiplication on 16-bit operands. The multiplier will identify the range of the operands during configuration register. The configuration register can be configured through input ports. The multiplier has been synthesized using Xilinx 14.5 and in this simulation we have achieve minimum combinational delay. Modelsim is used for the simulation part in this work.

An Area Efficient and High Speed Reversible Multiplier Using NS GateIJERA Editor
In digital computer system a major problem has been found that the Power dissipation which leads to bring some research on the methods to decrease this Area efficient, high speed. This is the main cause to give birth to reversible computing systems for digital computers and designs. Reversible computing is the path to future computing technologies, which all happen to use reversible logic. In addition, reversible computing will become mandatory because of the necessity to decrease power consumption. Reversible logic circuits have the same number of inputs and outputs, and have one-to-one mapping between vectors of inputs and outputs; thus the vector of input states can be always reconstructed from the vector of output states. Consequently, a computation is reversible, if it is always possible to uniquely recover the input, given the output. Each gate can be made reversible by adding some additional input and output wires if necessary. The main aim of this reversible computing is to lower the power dissipation, area efficient and high speed and some other advantages like security of data and prevention of errors etc... Reversible logic has so many applications low power CMOS, nanotechnology, DNA computing and quantum computing. There are two primary design implementations in this study which are the major spotlights. The first one is reversible design gate and the second one is multiplier design using reversible gates. In this manuscript we have implemented a 8 * 8 reversible design called “NSG(Non linear Sign Flip)”. The total project is implemented in Xilinx 14.7 ISE with Spartan 3E family.
Design of Multiplier Less 32 Tap FIR Filter using VHDLIJMER
This Paper provide the principles of Distributed Arithmetic, and introduce it into the FIR
filters design, and then presents a 32-Tap FIR low-pass filter using Distributed Arithmetic, which save
considerable MAC blocks to decrease the circuit scale and pipeline structure is also used to increase the
system speed. The implementation of FIR filters on FPGA based on traditional method costs considerable
hardware resources, which goes against the decrease of circuit scale and the increase of system speed.
It is very well known that the FIR filter consists of Delay elements, Multipliers and Adders. Because of
usage of Multipliers in early design gives rise to 2 demerits that are:
(i) Increase in Area and
(ii) Increase in the Delay which ultimately results in low performance (Less speed).
So the Distributed Arithmetic for FIR Filter design and Implementation is provided in this work to solve
this problem. Distributed Arithmetic structure is used to increase the recourse usage and pipeline
structure is used to increase the system speed. Distributed Arithmetic can save considerable hardware
resources through using LUT to take the place of MAC units

Survey of Optimization of FFT processor for OFDM Receiversijsrd.com
In the last few years wireless communications have experienced a fast growth due to the high mobility that they allow. However, wireless channels have some disadvantages like multipath fading that make them difficult to deal with. A modulation that efficiently deals with selective fading channels is OFDM. There are a large number of FFT algorithms and architectures in the signal processing literature. Therefore, the state of art algorithms and architectures should be analyzed and compared. Based on different algorithms and architectures, different power consumptions, area and speed of the processor will be achieved. So their ASIC suitability should be analyzed and the effort should be focused on the choosing algorithms and architectures and optimization. In this paper FFT Processor with Pipelined Architecture and CORDIC based ROM-free twiddle factor generator is proposed. The proposed algorithm and architecture should be validated by MATLAB simulation before implementation. After that, it is implemented on DSP Processor kit with Code Composer Studio. The synthesis results will be compared with other published FFT processor results.
Design of Scalable FFT architecture for Advanced Wireless Communication Stand...IOSRJECE
Now a day’s numerous wireless communication standards have raised additional stringent requirements on each throughput and flexibility for FFT computation. Advanced wireless systems support multiple standards to satisfy the demands of user application necessities. A wireless system whereas supporting multiple standards should also satisfy performance necessities of these supported standards. Meeting performance requirements of multiple standards is a challenge while designing a system. Fast Fourier transformations, a kernel processing task in communication systems, are studied intensively for efficient software and hardware implementations. To design an efficient system, it's necessary to efficiently design its performance critical component. each system must meet stringent design parameters like high speed, low power, low area, low cost, high flexibility and high scalability, designing FFT processor to support multiple wireless standards whereas meeting the above such performance necessities is a difficult task. This paper proposed a highly efficient scalable architecture, software tools design, and design implementation. The reconstruction of the FFT computation flow is design into a scalable structure. The FFT can be easily expanded for any-point FFT computation. The various parameters satisfied the conditions, gives proper and efficient outputs as compare to other platforms.
Area and Speed Efficient Reversible Fused Radix-2 FFT Unit using 4:3 Compressoridescitation
In this paper, it is proposed to design an area and speed efficient reversible fused
Radix -2 FFT unit using 4:3 compressor. Radix-2 Reversible FFT unit requires 24-bit and
48 – bit reversible adders, 24 – bit and 48 – bit reversible subtractors and 24x24 reversible
multiplier units. In the proposed architecture, the 24-bit adder has been realized as a
reversible carry-look-ahead adder using PRT-2 gate. The proposed reversible carry-look-
ahead adder is efficient in terms of transistor count, critical path delay and garbage outputs.
Reversible subtractor is realized using TR gate with less critical path delay. The 24x24 bit
multiplication operation is fragmented to nine parallel reversible 8x8 bit multiplication
modules. It is proposed to design a new reversible design of the 24x24 bit multiplier in which
the partial products are added using reversible 4:3 compressors which were realized using
PRT-2 gates. The proposed multiplier is optimized in terms of critical path delay and
garbage outputs. This paper describes three reversible fused operations and applies them to
the implementation of Fast Fourier Transform Processors. The fused operations are
reversible add-subtract unit, reversible multiply-add unit and reversible multiply-subtract
unit. Thus, Reversible Radix-2 FFT butterfly unit is implemented efficiently with the three
fused operations. The fused reversible FFT unit using 4:3 compressor operates at a greater
speed and consumes lesser amount of logic resource than the discrete implementation.
Efficient Design of Ripple Carry Adder and Carry Skip Adder with Low Quantum ...IJERA Editor
The addition of two binary numbers is the important and most frequently used arithmetic process on
microprocessors, digital signal processors (DSP), and data-processing application-specific integrated circuits
(ASIC). Therefore, binary adders are critical structure blocks in very large-scale integrated (VLSI) circuits.
Their effective application is not trivial because a costly carry spread operation involving all operand bits has to
be achieved. Many different circuit constructions for binary addition have been planned over the last decades,
covering a wide range of presentation characteristics. In today era, reversibility has become essential part of
digital world to make digital circuits more efficient. In this paper, we have proposed a new method to reduce
quantum cost for ripple carry adder and carry skip adder. The results are simulated in Xilinx by using VHDL
language.

The reversible logic gates are used to improve the power dissipation in modern computer applications. The floating-point numbers with reversible features are added advantage to performing complex algorithms with highperformance computations. This manuscript implements an efficient reversible floating-point arithmetic (RFPA) unit, and its performance metrics are realized in detail. The RFP adder/subtractor (A/S), RFP multiplier, and RFP divider units are designed as a part of the RFP arithmetic unit. The RFPA unit is designed by considering basic reversible gates. The mantissa part of the RFP multiplier is created using a 24x24 Wallace tree multiplier. In contrast, the reciprocal unit of the RFP divider is designed using Newton Raphson’s method. The RFPA unit and its submodules are executed in parallel by utilizing one clock cycle individually. The RFPA unit and its submodules are synthesized separately on the Vivado IDE environment and obtained the implementation results on Artix-7 field programmable gate array (FPGA). The RFPA unit utilizes only 18.44% slice look-up tables (LUTs) by consuming the 0.891 W total power on Artix-7 FPGA. The RFPA unit sub-models are compared with existing approaches with better performance metrics and chip resource utilization improvements.
FPGA based Efficient Interpolator design using DALUT Algorithmcscpconf
Interpolator is an important sampling device used for multirate filtering to provide signal processing in wireless communication system. There are many applications in which sampling rate must be changed. Interpolators and decimators are utilized to increase or decrease the sampling rate. In this paper an efficient method has been presented to implement high speed and area efficient interpolator for wireless communication systems. A multiplier less technique is used which substitutes multiplyand-accumulate operations with look up table (LUT) accesses. Interpolator has been implemented using Partitioned distributed arithmetic look up table (DALUT) technique. This technique has been used to take an optimal advantage of embedded LUTs of the target FPGA. This method is useful to enhance the system performance in terms of speed and area. The proposed interpolator has been designed using half band poly phase FIR structure with Matlab, simulated with ISE, synthesized with Xilinx Synthesis Tools (XST) and implemented on Spartan-3E and Virtex2pro device. The proposed LUT based multiplier less approach has shown a maximum operating frequency of 92.859 MHz with Virtex Pro and 61.6 MHz with Spartan 3E by consuming considerably less resources to provide cost effective solution for wireless communication systems.

This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
