The determined state of the control.

Description

technical field [0001] The invention relates to a reversible logic circuit, in particular to a reversible double-edge T flip-flop capable of asynchronously setting numbers, which is composed of a Feynman reversible logic gate and a Fredkin reversible logic gate. Background technique [0002] How to reduce circuit power consumption is a key issue in integrated circuit design at present. In the traditional non-reversible logic circuit, the loss of information bit data is the main cause of circuit power consumption. Therefore, the design of reversible logic circuit that can avoid the loss of information bit data has become a way of low power consumption design. At the same time, reversible logic circuits are also an important part of quantum computing and quantum information technology research. [0003] Reversible logic circuits include reversible combinational logic circuits and reversible sequential logic circuits. In the reversible sequential logic circuit, the importance...
