Abstract: 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.

摘要： 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。
