论文摘要
许多论文都提出了各种技术中的多价电路，以减少或解决二进制电路中的互连问题的解决方案。讨论了这个假设。虽然4值信号可能除以两个构件之间的互连数量的数量，但事实证明，电路设计人员使用基于差异对的互连标准，例如PCIE，Infiniband，Rapidio，NVLink等。将二进制信号的数量增加一倍，是使用单端的四级信号更好的解决方案。将第四纪基本门，加法器和乘数的设计与相应的二进制文件进行了比较。 在每个级别，第四纪和二进制电路之间的晶体管计数比大于基本4和基数2之间的x2信息比。第四纪信号传导不是电路块之间或之内的解决方案。
Many papers have presented multi-valued circuits in various technologies as a solution to reduce or solve interconnection issues in binary circuits. This assumption is discussed. While 4-valued signaling could divide by two the number of interconnects between building blocks, it turns out that circuit designers use interconnect standards based on differential pairs such as PCIe, Infiniband, RapidIO, NVLink, etc. Doubling the number of binary signals is a better solution than using single-ended quaternary signals. The design of quaternary basic gates, adders and multipliers are compared with the corresponding binary ones. At each level, the transistor count ratio between quaternary and binary circuits is greater than the x2 information ratio between base 4 and base 2. Quaternary signaling is not a solution, either between or within circuit blocks .
