三态编码方法及实现电路的研究

Research on trinary data encoding method and realized circuit

定义了(N,M)三态编码电路模型。基于三态数据编码(BCT)算法,讨论了三态编码的硬件设计方法。设计了"除3求余"电路模块,并采用"模块组合"设计方法,实现了任意(N,M)模型的三态编码电路。该方法的主要优点是能够适应定义模型下的不同规模的动态需求。最后,作为示例,给出了(4,2)三态编码模型的硬件结构电路。

Based on the Binary-Coded Trinary（BCT） encoding algorithm, some trinary data encoding methods are discussed.A ＂module-combination＂ design method is proposed and used in the design and realization of the trinary data encoding circuit using division-by-three modules.The method has several advantages over the other proposed methods,especially in that it is flexible and adaptive to design corresponding three-state encoding circuit for different model（N,M） presented in the paper.As an illustrative example,a （4,2） model trinary encoding circuit is constructed.
