摘要
针对目前集成电路的发展和市场上的PLA(可编程逻辑阵列)芯片,本文采用一片PLA分块设计或多个PLA级连的方法,设计了一种完全校验的比较器基本单元,用它可以实现任意输入(4、8、16、32…)位数的比较器,这种比较器可以广泛地应用于双模(机)冗余系统中。
With the development of commercially available PLA chips, the paper discusses the method of partitioning of one PLA chip or interconnecting of several PLA chips in cascade. According to these principles, a comparator with an arbitrary number of imputs(4, 8, 16, 32 etc.) is designed. This comparator is totally selfchecking and can be widely applied to dual-microcomputer fault-tolerant systems.
