摘要:

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。

Abstract:

A clock edge controllable dual edge-triggered D flip-flop is presented using the cellular neural network (CNN). Based on analysis of the relevance of uncoupled CNN and linear separable boolean function, a fundamental approach to implement logical circuit with uncoupled CNN is described. Implementation of the new D flip-flop circuit also is discussed. Different from traditional D flip-flop, this new method is a reconfigurable component, which can implement the up edge-triggered D flip-flop; the down edge-triggered and the dual edge-triggered respectively only by changing the gene parameters of CNN. Thus, a new method to design the reconfigurable logical circuit is created.

Key words: cellular neural network, reconfigurable circuit, D flip-flop, dual edge-triggered D flip-flop
