In the Modern computers for performing the operationof ALU (Arithmetic Logic Unit) like Addition, Subtraction, different types of adders are using for achieving low delay and fastoutput. QSD numbers are using for giving the carry-free additionso that ALU operations can perform in low delay and speed of themodern computer can increase. In the modern digital system fastadder, Subtraction can perform...

Big Data is a term which denotes data that is beyond storage capacity and processing capabilities of classical computer and getting some insight from large amount of data is a very big challenge at hand. Quantum Computing comes to rescue by offering a lot of promises in information processing systems, particularly in Big Data Analytics. In this paper, we have reviewed the available literature on Big...
Distributed MIGFET (Multiple Independent Gate Field Effect Transistor) based “Equivalent Circuit” design requires multiple channels adjacent to one another for optimization. To test a particular behavior of carriers in nMOS, a particle-based simulation is carried out. Due to the limited resources, the scale and complexity of the simulation is kept at a minimum. It has been found in the simulation...
Quantum computing is no longer a future technology. Recent advances in D-Wave computers based on quantum annealing and superconducting devices, and the demonstration of long spin decoherence times in isotopically-enriched Si qubits, have accelerated the research and development of this technology. The remaining challenge is large scale integration of qubits. Physically-defined coupled quantum dots...
Quantum computing field is evolving rapidly these days. The difference between this new field and the classical field is the extension of the main domain from just using two bits (0, 1) to a complete space which is the result of the superposition of the same mentioned bits. By applying the superposition property in the quantum algorithms, this ensures that the system is more secured than the classical...
Quipper is the most recently developed quantum programming language. In this work, we provide brief background information about Quipper and use its framework to demonstrate the implementation of five non-trivial reversible gates. Each gate works as a full adder gate. We will use a Quipper simulator to run a simulation for each gate on a classical computer.
Stochastic computing using simple logic circuits requires significantly less area and consumes less power compared to traditional computing systems. These circuits are also inherently fault-tolerant. The main drawbacks of these systems include long latency and inexactness in computing. The deviation from exact values increases as the correlation among inputs increases. In many applications, outputs...
As quantum computers of non-trivial size become available in the near future, it is imperative to develop tools to emulate small quantum computers. This allows for validation and debugging of algorithms as well as exploring hardware-software co-design to guide the development of quantum hardware and architectures. The simulation of quantum computers entails multiplications of sparse matrices with...
This paper addresses implementations of tangent hyperbolic and sigmoid functions using stochastic logic. Stochastic computing requires simple logic gates and is inherently fault-tolerant. Thus, these structures are well suited for nanoscale CMOS technologies. Tangent hyperbolic and sigmoid functions are widely used in machine learning systems such as neural networks. This paper makes two major contributions...
This work presents improved implementations of memristor-based ripple carry adders using three different approaches: the IMPLY operation, hybrid-CMOS gates, and threshold gates. The designs are optimized by performing parallel operations, leveraging computational redundancies, and recognizing Boolean simplifications. The proposed IMPLY N-bit ripple carry adder decreases the area by 2N-1 components...
The reversible logic has been proved to play an important role in the low power VLSI design arena and the quantum dot cellular automata. The reversible circuits are building blocks of quantum computers since the operations involved in this are reversible. This paper proposes a novel 4*4 reversible gate called BKG gate. The most significant feature of the proposed gate is that it can be operated singly...
The rapid advancements in VLSI industry continue to establish a smaller feature size, causing the integration of more millions of transistors on a single piece of silicon according to Moore’s law. Hence, an increase in the number of transistors induces power dissipation. Modern studies explain that power dissipation can be reduced by reversible gate technique. A central issue is the lack of use of...
In the paper we interpret the Church Turing thesis of Computation Algorithm and how it differs from the strong Church Turing thesis in the field of computation. Church Turing thesis can be classified as Strong Church Turing thesis and Normal Church Turing thesis. Church Turing hypothesis says “that a computing problem can be solved in any computer if and only if it can be solved on a very simple ‘machine’,...
The demand for Solid-State drives (SSDs) has risen as their speed, size, and architecture have improved. SSDs introduce a security risk because they contain a separate processor to optimize the SSD's lifespan. The lack of transparency of the operations conducted by this onboard processor creates a challenge to users, particularly in digital forensics settings. This paper utilizes non-destructive voltage...
this paper aims to present a students' clustering method based on their backward knowledge of a specific domain. The categorization process uses the tracking information of students' answers in multiple choice questions (MCQ). We used an enhanced MCQ representation in which all the choice items (right or wrong) are linked to an existing conceptual map. We track the students' answers and propose a...
Superconductor electronics holds records for clock frequency and energy efficiency at the chip level, and is also projected to large systems that can absorb the cooling overhead. These advantages have nevertheless only managed to give this technology a back seat to CMOS digital circuits, which offer orders of magnitude more complexity. Furthermore, pursuing the CMOS paradigm with superconductor circuits...
The “bring your own experiment” movement is being incorporated in universities all over the world. This movement is centered on students purchasing low cost hardware for use in their courses. This paper discusses the inclusion of the Basys-3 FPGA Trainer available through Digilent in a lecture only, sophomore year, Digital Logic Fundamentals course. The enhancements to this course also include the...
At roughly kT energy dissipation per operation, the thermodynamic energy efficiency “limits” of Moore's Law were unimaginably far off in the 1960s. However, current computers operate at only 100–10,000 times this limit, forming an argument that historical rates of efficiency scaling must soon slow. This paper reviews the justification for the ∼kT per operation limit in the context of processors for...
People have access to more data in single day than most people that have access to data in the previous decade. This data is created in many forms and it highlights the development of Big Data. Big Data in organizations have transformed the way organizations across industries implement new approach to handle huge amount of data.
