摘要:

不同于以往一种可逆触发器电路只能实现单一的D,T或JK触发器功能,本文在提出的3种触发器统一的次态方程基础上,设计了功能可配置的可逆单边沿和双边沿触发器.通过对输入变量的设置,提出的可逆触发器电路分别具有D,T或JK触发器逻辑功能,并能实现异步置数.提出的可逆触发器用Verilog硬件描述语言建模并用Modelsim软件仿真验证逻辑功能的正确性.相比于已有的单一功能可逆触发器,本文的可逆触发器在增加有限量子代价的基础上用单一电路实现3种不同触发器功能和异步置数.

Abstract:

Unlike the previous reversible flip-flops(RFFs) which have a single D, T or JK flip-flop characteristic function for one circuit, an edge-triggered(including dual edge-trigged) RFF with function configurable(FCRFF) is designed based on the proposed unified characteristic equation of D, T and JK FFs. By preset some inputs of FCRFF, the proposed edge-trigged FCRFF can act as D, T and JK reversible FF and also can load data asynchronously. The functions of proposed FCRFF are approved by simulation using Modelsim after modeled with Verilog HDL. Comparing with those published D, T and JK reversible FFs, the proposed FCRFF can combine D, T and JK reversible FFs' functions into one circuit and have asynchronous data loading function additionally only with a few quantum cost increasing.

Key words: reversible logic, reversible flip-flop, reversible dual edge-trigged flip-flop, reversible sequential circuit
