针对逻辑级的功耗优化问题,本文提出了一种基于AIG(And Inverter Graphs)的双逻辑电路功耗优化方法。以AIG表示逻辑函数,开关活动性作为功耗成本,通过结点压缩优化AIG,达到优化功耗的目的。实验结果表明,所建议的方法能有效地降低电路总开关活动性,从而达到降低功耗的目的。 In order to solve the problem of logic level power optimization, this paper presents a method of power optimization based on AIG (And Inverter Graphs) for dual logic circuits. Using AIG as a logic function and switching activity as a power cost, AIG is optimized by node compression to optimize power consumption. Experimental results show that the proposed method can effectively reduce the total circuit switch activity, so as to achieve the purpose of reducing power consumption.
