摘要
量子元胞自动机(QCA)是一种纳米范围内不含晶体管的计算范例。基于QCA提出了QCA奇偶校验系统电路的分块设计方法。首先设计了异或门、奇偶判断单元,再运用分块设计思想构建了奇数产生电路和奇偶校验电路的结构,所设计的电路拥有尺寸极小和功耗极低等优点,QCADesigner软件仿真结果验证了设计的有效性。
Quantum-dot cellular automata（QCA） is a transistorless computing paradigm at the nanoscale.QCA parity checker with modularization design method is proposed based on QCA.Firstly,exclusive-OR gate and parity judgment unit are designed,and then odd generation circuit and parity checker system are designed with modularization method based on aforementioned circuit units.The proposed circuits have the advantages of ultra small size and low power consumption.Simulations by QCADesigner demonstrate the validity of the proposed circuits.
