比较器在数字计算机逻辑电路及数字设备中应用非常广泛。多位比较器可用二位或一位比较器做基本单元串联而成,然而,速度较慢。也可进行独立设计,困难在于变量太多,函数化简较为麻烦。本文介绍我所新研制的757大型计算机指令控制部件中,实际采用的一个19位比较器及其设计方法。 Comparators are widely used in digital computer logic circuits and digital devices. Multiple comparators can use two or a comparator as the basic unit in series, however, slower. Can also be independently designed, the difficulty is that too many variables, function simplification more trouble. This article describes my newly developed 757 large computer instruction control components, the actual use of a 19-bit comparator and its design method.
