Abstract

The invention discloses a generalized pipeline cellular circuit of a quantum cellular automaton. On the premise of not changing the logic function of the circuit, by introducing a three-input XOR logic gate, the circuit is optimized and designed at the logic level. In the automaton, a generalized pipeline cell circuit that can realize multi-bit and various logic operations is realized. Compared with the traditional 5-bit pipeline cell circuit with the best performance, the area and delay of the general arithmetic unit of the cell circuit of the present invention are reduced by 69.12% and 75%, respectively, and the area and delay of the control unit are respectively reduced by 54.55% and 33.33% , the overall area and delay of the cell circuit of the present invention are reduced by 21.30% and 21.13% respectively. It can be seen that the generalized pipelined cellular circuit based on the quantum cellular automata designed by XMG in the present invention greatly reduces the cost of circuit design, and has strong practical significance for the development of circuit design automation.

Description

technical field [0001] The invention relates to the technical field of quantum cellular automata circuit design, in particular to a generalized pipeline cellular circuit of a quantum cellular automaton capable of realizing multi-bit and multiple logic operations. Background technique [0002] With the continuous development of traditional CMOS technology, the continuous improvement of chip integration and the continuous reduction of device physical size, nano-scale CMOS technology is facing the trouble caused by leakage power caused by leakage current. On this basis, nanotechnology continues to rise, such as DNA logic, spin wave devices, quantum cellular automata (Quantum-dot Cellular Automata, QCA), etc., QCA has the characteristics of high integration and low power consumption, and is considered to be the One of the technologies to replace the CMOS process. The basic units of QCA are three-input majority gate (Majority Gate) and inverter (Inverter), so the traditional QCA...
