摘要
针对可逆逻辑综合在设计较大规模可逆逻辑电路(ALU)时遇到的瓶颈问题。文中借用现行EDA技术的逻辑描述和验证能力,可逆逻辑门的功能表达式为依据,设计具有等功能的常规逻辑组合电路,通过等功能代换的方法,设计实现以常规原理图方式描述的可逆ALU。仿真图中显示的16种运算结果表明,该方法具有一定的可行性和有效性。
For of the rent EDA technology to expressions to solve the encountered, this paper design adopts classical logic circuits bottlenecks of reversible logic versible ALU, described with conventional logic the logic description and verification capability of the cur- as the replacement of reversible logic gates based on functional synthesis in case of great circuit scale and complexity. The re- diagram , implements sixteen logic operations. Experimental resuhs show that the proposed method is feasible and effective.
