摘要: 提出了在三值光计算机中采用对称三进制半加器的观点,设计了支持这个观点的半加器结构原理图。与传统二进制电子计算机加法器相比,该设计体现了对称三进制表示将加法运算和减法运算合而为一的优点,避免了补码运算。论述了对称三进制加法运算的规律,介绍了所设计半加器的工作原理,为三值光计算机逻辑运算器以及后续研究提供了理论指导意义。

Abstract: This paper brings forward a new viewpoint of using balanced ternary half-adder in the ternary optical computer. A half-adder principle plan is designed based on this viewpoint. Compared with adder of tradition binary electric computer, the strongpoint of this design is that subtraction can be done without complementing code. The add-rule of balanced ternary is discussed and the work methods of balanced ternary half-adder are also provided, which are the theory guidance of Boolean calculator and extended research of ternary optical computer.

Key words: optical computer, half-adder, ternary computer, balanced ternary
