面向双逻辑域的忆阻逻辑综合研究
A Research on Logic Synthesis for Dual-domain Memristive Circuits
摘要
Abstract
Memristors,originally exploited for nonvolatile storage,are now intensively investigated as logic primitives capable of in-memory computing,offering a promising solution to break the"memory wall".However,when targeting the design of large and complex circuits,existing synthesis flows restricted to a single memristive logic lack the flexibility,leading to results that the performance metrics of circuits fall short of design targets.In this work,a dual-domain synthesis framework is proposed that synergistically combines memristor-based implication(IMP)logic and not-implication(N-IMP)primitives.By systematically analyzing their mapping and scheduling characteristics on circuit netlists,three cooperative strategies are introduced during the process of technology-independent optimization:optimization for rewriting the minimal-substructure,disjunctive/conjunctive duality selection for multiplexers,and collective refactoring of multi-fan-out clusters.The proposed methods achieve high-performance graph topology transformation and scheduling.Experimental results show that,compared with ABC tool,the proposed methods achieve the reduction of number of nodes after mapping by 17.32%.Furthermore,the proposed methods achieve the improvement in area overhead by 61.5%during the process of scheduling,when compared with the state-of-the-art work(AND-OR).关键词
