Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] The generalized pipeline cell circuit of the quantum cellular automaton that the present invention proposes is 5 pipeline cell circuits, such as figure 1 As shown, the generalized pipeline cell circuit is distributed on the circuit layout composed of three circuit layers. The generalized pipeline cell circuit has five levels, which are composed of thirty-five general arithmetic units and five control units. Each level Including 2N+1 general-purpose arithmetic units and a control unit, N represents the number of stages, N is a positive integer, N=1,2,...,5; the control unit in each level of generalized pipeline cell circuit is located in the generalized pipeline cell of this level On the far left side of the circuit, one output C of each general-purpose arithmetic unit in each stage of the generalized pipeline cell circuit 0 From right ...

Abstract

The invention discloses a generalized pipelined cell circuit of a quantum cellular automaton. On the premise that the logic function of the circuit is not changed, a three-input exclusive-OR logic gate is introduced, the circuit is optimally designed on the logic level, and the generalized pipelined cell circuit capable of achieving multi-bit and multi-logic operation is achieved in the quantum cellular automaton. Compared with a traditional similar five-bit assembly line cell circuit with the optimal performance, the circuit reduces the area and delay of the general arithmetic unit of the cell circuit respectively by 69.12% and 75%, reduces the area and delay of the control unit by 54.55% and 33.33% respectively, and reduces the overall area and delay by 21.30% and 21.13% respectively. Therefore, the generalized assembly line cell circuit of the quantum cellular automaton based on the XMG design greatly reduces the expenditure 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 Cellular Automata, QCA), etc. QCA has the characteristics of high integration and low power consumption, and is considered to be an alternative to CMOS technology. One of the techniques. The basic units of QCA are three-input majority gate (Majority Gate) and inverter (Inverter), so the traditional QCA cir...
