Computação reversível: fundamentos e aplicações

Abstract

Motivated by its promising applications, reversible logic has received significant attention. As a result, impressive progress has been made in developing synthesis approaches, implementing sequential elements, and hardware description languages. In this monograph, these recent achievements are employed for PDP-8 and RISC architecture in reversible logic that can run software programs written in assembly language. The respective combinational and sequential components are designed using state-of-the-art design techniques. Encouraged by the importance of studying the existence of logically reversible automata, it suggests that physical computers can become thermodynamically reversible and therefore able to dissipate an arbitrarily small amount of energy in steps if operated slowly enough. Today's computers are based on irreversible logic devices, which have been known to be fundamentally energy-inefficient for several decades. The idea is to understand the concepts in reversible logic in irreversible logics that can run software programs written in assembly language. In traditional models of computation, sheer reversibility appears to decrease overall computational efficiency. However, traditional models ignore important physical constraints on information processing. Very simple reversible programming languages can be useful for studying reversible transformations. This study processes concepts and knowledge to develop the improvement in functionality and performance of a reversible programming environment.
