Abstract and Keywords

Abstract: Quantum cellular automata(QCA) is considered as a new technology that is expected to replace complementary metal-oxide-semiconductor (CMOS) because of its small size, low power consumption and high speed. However, wire crossing has always been a difficult problem in its circuit design, which not only brings considerable design cost, but also increases the complexity and noise sensitivity of the circuit. In this paper, 13 kinds of three-input standard functions are redesigned by using some new logic gates. These new designs achieve the goal of no wire crossing, and the total cell count, circuit area, and latency are optimized by 18.4%, 15.4%, and 21.2%, respectively, compared with those of the best previous designs.

Keywords: quantum cellular automata(QCA); QCA logic gate; standard function; wire crossing

摘要和关键词

摘要: 量子元胞自动机(quantum cellular automata, QCA)以其小尺寸、低功耗、高速度等特点被认为是一种有望取代互补金属氧化物半导体(complementary metal-oxide-semiconductor, CMOS)的新兴技术,但是其电路设计中导线交叉一直是个难点问题,该问题不仅带来相当高的设计成本,还会增加电路的复杂性和噪声敏感性。文章通过使用一些全新的逻辑门,重新设计了13种三输入标准函数,新设计实现了无导线交叉的目标,并且与之前最好的设计相比,在总的元胞数量、电路面积和延迟等方面分别优化了18.4%、15.4%、21.2%。

关键词: 量子元胞自动机（QCA）；QCA逻辑门；标准函数；导线交叉
