提出一种由细胞神经网络(CNN)实现的时钟边沿可控的双边沿D触发器.结合非耦合CNN与线性可分布尔函数之间的关联性,提出了非耦合CNN实现逻辑电路的基本方法.通过分析D触发器工作原理,设计出基于非耦合CNN的D触发器电路结构.相比较传统的D触发器,新设计的D触发器具有动态可重构性,即保持电路结构和内部连线不变,仅改变基因参数,可分别实现上升沿触发、下降沿触发以及双边沿触发.本研究为进一步设计动态可重构逻辑电路提供了一种新的方法.
A dual edge D flip-flop with controllable clock edges is proposed by cellular neural network (CNN) .According to the relation between uncoupled CNN and linear distributable Boolean function, a basic method of uncoupled CNN logic circuit is proposed By analyzing the working principle of D flip-flop, we designed a D flip-flop circuit based on uncoupled CNN.Compared with traditional D flip-flop, the newly designed D flip-flop has the characteristics of dynamic reconfigurability, that is, the circuit structure and interconnection Only changing the gene parameters can realize the rising edge trigger, the falling edge trigger, and the double edge trigger respectively.This study provides a new method to further design dynamic reconfigurable logic circuits.
