三值动态和静态广义时序机理论

该文在三值电路三要素理论的基础上提出了三值动态和静态广义时序机理论。首先找出三值状态图和电路方程间的关系,该关系既适用于静态电路,又适用于动态电路。对静态电路文中推导出各型三值触发器完整特性方程,它描述了触发器全时刻的行为,用以代替常规特性方程,使三值同步和异步时序电路统一。对动态电路该文用电容代替触发器存储三值信息,实现三值动态时序电路(特别是三值同步动态时序电路,属于非触发器式的时序电路)。因动态电路和静态电路主要差别是负载行为,故此可以在三值电路三要素理论和广义时序机理论下统一三值动态和静态,同步和异步时序电路。

Theory of Ternary Dynamic and Static Generalized Sequential Machine

On the basis of theory of ternary essential circuits elements, this paper presents a theory of ternary dynamic and static generalized sequential machine, which is applicable to static circuits as well as dynamic circuits. As regards static circuits, several ternary flip-flops perfect characteristic equations are proved to describe its action at all times, instead of its traditional characteristic equations, in order to unify the theory of temary sychronous and asychronous sequential circuits. As regards dynamic circuits, this paper uses capacitors, instead of ternary flip-flops, to memorize ternary informations for the realization of ternary dynamic circuits, especially temary sychronous dynamic sequential circuit without flip-flops, because the difference between dynamic circuit and static circuit is mainly its load property. The theory of ternary essential circuit elements is a very useful means for unifying sequential circuit theory between static circuits and dynamic circuits, and between ternary sychronous and asychronous sequential circuits.
