基于连续逻辑的十值十进制算术运算电路的设计

A Design of the Ten-Valued Decimal Arithmetical Unit Based on the Continuous Logic

本文提出了用ＤＹＬ系列器件构成的直接用十进制进行运算的十值电路；ＤＹＬ器件是一种线性元件，它可以工作于０～３Ｖ范围内的任意信号电压，对信号的分辨率极高，为实现高信息密度的十值电路提供了方便条件。本文提出的电路其工作原理是基于一种我们称之为＂赋值－选通＂的方法。将可能的输出值全部赋予电路，根据输入信息，通过选通电路直接将计算结果输出。这种赋值－选通法对多值电路的设计有普遍意义。

A ten-valued circuit of decimal arithmetical unit using DYL devices is presented. The DYL device is a kind of linear element,able to work at any voltage between 0-3 volts with high resolution to signals.This gives a good ground for the realization of the ten-valued logic circuits,with high information density. By designing the circuit, a method called'data assigning and selective output'(DASO) is adopted. All possible values of the output are assigned to the circuit,and proper output is selected out according to the input signals. The method of DASO is of general significance to the design of multiple-valued circuits.
