As the conventional irreversible logic dissipates power for losing bits of information, computing engines has to be designed that do not require energy dissipation but only if computation is done logically reversible. Hence, research on reversible logic has been extensively increased now-a-days for its application in Quantum Computing, nanotechnology, QCA(More)
One-to-one mapping from input to output is the necessary condition for a reversible computational model transiting from one state of abstract machine to another. Probably, the biggest motivation to study reversible technologies is that, it is considered to be the best effective way to enhance the energy efficiency than the conventional models. The research(More)
Discrete cosine transform (DCT) is the most widely used transformation technique in the field of signal processing particularly in the areas of image data. This paper addresses the design of parallel architectures for computing DCT using CORDIC. It concentrates on indirect methods, which avoids decomposition of direct DCT equation. In this paper, CORDIC(More)
This paper is a study of linear phase low pass FIR filter design using different particle swarm optimization techniques (PSO). FIR filter design is basically a multi-modal optimization problem. Evolutionary algorithms like particle swarm optimization (PSO) can be used for the design of linear phase FIR low pass (LP) filter. Different improved particle swarm(More)
A discrete cosine transform (DCT) is described and a technique to compute it using fast Fourier transform (FFT) is developed. In this work, DCT of a finite length sequence is obtained by incorporating CORDIC methodology in radix-2 FFT algorithm. The proposed methodology is simple to comprehend and maintains a regular structure, thereby reducing(More)
The growing demand of low power electronics equipments has forced the research community to think of some methods by which energy of a circuit can be recycled and then adiabatic logic was born. The literature has experienced a numerous number of adiabatic circuits which faces a lot of complication in terms of glitch, noise and huge no. of transistors(More)
As the chip size is getting decreased with the advent of technology, power dissipation has become a major issue to the circuit designers at the time of designing an integrated circuit. The substantial sources of power dissipation are the static power and dynamic power. A serial adder, one of the vital parts of any processor micro-architecture, is a victim(More)
As technology scales down toward deep submicron, large numbers of IP blocks are being integrated on the same Silicon die, thereby enabling large amount of parallel computations, such as those required for multimedia workloads. Network-on-chip (NOC) serves as an important agent to eliminate the communication bottleneck of future multicore systems. Arbiter, a(More)
