A General Method of Constructing the Reversible Full-Adder
Lihui Ni, Zhijin Guan, Wenying Zhu · 2010
The reversible gates, attracting people's attention increasingly, have been widely used in low-power CMOS design, optical computing and quantum computing. In many existing literatures, only the methods of constructing certain specific reversible full-adders were presented, while we proposed a general approach to construct the reversible full-adder. According to the approach, we can realize a variety of reversible full-adders flexibly with only two reversible gates and two garbage outputs, which have improvements in the gate count and garbage count and can reduce the cost of network.
