Zusammenfassung Traditionelle Technologien (z. B. CMOS) stoßen durch die stetig steigende Miniaturisierung sowie das exponentielle Wachstum der Anzahl an Komponenten immer mehr an ihre Grenzen. Daher werden in Zukunft Alternativen, welche traditionelle Computerchips ersetzen oder zumindest ergänzen, benötigt. Reversible Logik mit ihren Anwendungen z. B. im Gebiet der Quantencomputer, des Low-Po...

An overview of nanocomputers is given, including a discussion of reversible computing techniques and an explanation of why they are necessary. 1 Nanocomputers I usually begin this talk by trying to justify why we need nanocomputers in the rst place. As Caxton Foster once said of associative memory, nanocomputers would seem to hold out the promise of sugar tomorrow to people drowing in honey tod...

The λ-calculus is destructive: its main computational mechanism – beta reduction – destroys the redex and makes it thus impossible to replay the computational steps. Combinatory logic is a variant of the λ-calculus which maintains irreversibility. Recently, reversible computational models have been studied mainly in the context of quantum computation, as (without measurements) quantum physics i...

The λ-calculus is destructive: its main computational mechanism – beta reduction – destroys the redex and makes it thus impossible to replay the computational steps. Recently, reversible computational models have been studied mainly in the context of quantum computation, as (without measurements) quantum physics is inherently reversible. However, reversibility also changes fundamentally the sem...

In recent years, reversible logic has emerged as a promising computing paradigm having application in low power CMOS, quantum computing, nanotechnology, and optical computing. The classical set of gates such as AND, OR, and EXOR are not reversible. In this paper, the authors have proposed reversible programmable logic array (RPLA) architecture using reversible Fredkin and Feynman gates. The pro...

Reversible logic has emerged as one of the most important approaches for the power optimization with its application in low power VLSI design. They are also the fundamental requirement for the emerging field of the Quantum computing having with applications in the domains like Nano-technology, Digital signal processing, Cryptography, Communications. Implementing the reversible logic has the adv...

This report provides an overview of the current state of reversible sequential logic. We assume that the reader has a basic knowledge of reversible logic. An overview of necessary information is provided in [1]. Most research in reversible logic has concentrated on synthesis techniques for combinational logic. Sequential logic synthesis requires the incorporation of memory cells and feedback in...

In the recent era, Reversible computing is a growing field having applications in nanotechnology, optical information processing, quantum networks etc. In this paper, the authors show the design of a cost effective reversible programmable logic array using VHDL. It is simulated on Xilinx ISE 8. 2i and results are shown. The proposed reversible Programming logic array called RPLA is designed by ...
