【摘要】 本文通过对2-3混值电路中信号编码效率与冗余度的讨论,分析了传统的1T-2B编码的缺点,提出了3B-2T编码方案,设计了用于3B-2T编码的CMOS接口电路。讨论表明,利用该编码的电路具有效率高,设计容易,并能在不增加电路内部连线的前提下减少三分之一的外部信号线等优点。更多还原

【Abstract】 By discussing efficiency and redundancy of signal-encoding in the 2-3 mixed-valued circuits, the drawbacks of conventional 1T-2B encoding is analysed, the 3B-2T encoding is proposed, and CMOS interface circuits for 3B-2T encoding are designed. The discussion shows that the circuits using 3B-2T encoding scheme have advantages of high efficiency, easy designing and reducing one third of external signal lines with the same internal binary interconnection.更多还原
