A representation changer is a function that converts a concrete representation of an abstract value into a different concrete representation of that value. Many useful functions can be recognised as representation changers; examples include compilers, and arithmetic functions such as addition and multiplication. Functions that can be specified as the right inverse of other functions are special...

We present the design of a quantum carry-lookahead adder using measurement-based quantum computation. The quantum carry-lookahead adder (QCLA) is faster than a quantum ripple-carry adder; QCLA has logarithmic depth while ripple adders have linear depth. Our design is evaluated in terms of number of time steps and the total number of qubits used.

Here we describe the design details and performance of proposed Carry Propagate Adder based on GDI technique. GDI technique is power efficient technique for designing digital circuit that consumes less power as compare to most commonly used CMOS technique. GDI also has an advantage of minimum propagation delay, minimum area required and less complexity for designing any digital circuit. We desi...

The main objective of this project is to design an efficient architecture for removal of random-valued impulse noise from captured image. A good image de-noising model property is that, it will remove noise while preserving edges. The decision-tree-based denoising method (DTBDM) is the proposed methodology for this project. It consists of decision tree based impulse detector, to detect the nois...

Design of areaand power-efficient highspeed data path logic systems forms the largest areas of research in VLSI system design. In digital adders, the speed of addition is limited by the time required to transmit a carry through the adder. Carry Select Adder (CSLA) is one of the fastest adders used in many data-processing processors to perform fast arithmetic functions. From the structure of the...

Parallel-prefix adders (also known as carrytree adders) are known to have the best performance in VLSI designs compared to that of conventional Ripple Carry Adder (RCA). However, each type of parallel prefix adder has its own pros and cons and are chosen according to the design requirement of the application. This paper investigates mainly two types of carry-tree adders, the brent kungg adder a...

Reversible logic has extensive applications in quantum computing, it is a unconventional form of computing where the computational process is reversible, i.e., time-invertible. The main motivation behind the study of this technology is aimed at implementing reversible computing where they offer what is predicted to be the only potential way to improve the energy efficiency of computers beyond v...
