摘要：Reversible computing spans computational models that are both forward and backward deterministic.These models have applications in program inversion and bidirectional computing, and are also interesting as a study oftheoretical properties. A reversible computation does, thus, not have to use energy, though this is impossible to avoid inpractice, due to the way computers are build. It is, however, not always obvious how to implement reversiblecomputing systems. The restriction to avoid information loss imposes new design criteria that need to be incorporatedinto the design; criteria that do not follow directly from conventional models.In this paper, investigate garbage-free reversible central processing unit computing systems to physical gate-levelimplementation. Arithmetic operations are a basis for many computing systems, so a proposed the design of adder, subtractor, multiplexer, encoder and work towards a reversible circuit for general circuit are important new circuits. In alldesign implemented Xilinx software and simulated VHDL text bench.
