Os circuitos lógicos adiabáticos são considerados uma das soluções mais atraentes para projetos de circuitos de baixa potência. Este estudo é dedicado a otimizar o projeto do circuito lógico adiabático de dois níveis (2LAL), que possui uma estrutura relativamente simples e desempenho superior de baixa potência entre muitas famílias lógicas assintoticamente adiabáticas ou quase adiabáticas, mas sofre de um grande número de buffers de tempo para “descomputação”. Nosso foco está na técnica de “descomputação antecipada” para 2LAL totalmente pipeline, e propomos duas abordagens de ILP para minimizar o custo de hardware por meio da otimização da descomputação antecipada. Na primeira abordagem, o problema é formulado como uma espécie de problema de escalonamento, enquanto é reformulado como problema de seleção de nós (problema de conjunto estável). O desempenho dos métodos propostos é avaliado utilizando vários circuitos de benchmark do ISCAS-85, e a redução máxima de hardware de 70% é observada em comparação com um método existente.

Abstract: Adiabatic logic circuits are regarded as one of the most attractive solutions for low-power circuit design. This study is dedicated to optimizing the design of the Two-Level Adiabatic Logic (2LAL) circuit, which boasts a relatively simple structure and superior low-power performance among many asymptotically adiabatic or quasi-adiabatic logic families, but suffers from a large number of timing buffers for “decompute”. Our focus is on the “early decompute” technique for fully pipelined 2LAL, and we propose two ILP approaches for minimizing hardware cost through optimization of early decompute. In the first approach, the problem is formulated as a kind of scheduling problem, while it is reformulated as node selection problem (stable set problem). The performance of the proposed methods are evaluated using several benchmark circuits from ISCAS-85, and the maximum 70% hardware reduction is observed compared with an existing method.
