数字逻辑化简是数字系统中的一个重要问题,经典方法采用布尔代数式和卡诺图化简,现代虽可采用计算机辅助逻辑综合,但在一般数字设备中,手工的卡诺图化简仍不失为有效手段,可是它在多变量(大于5、6变量)的情况下,便难于处理,为此,如何充分发挥现有中规模器件集成度较高的优点,扩展其逻辑功能,以便用于常用数字系统中组合逻辑及时序逻辑网络综合。多路选择器在处理这类问题上,有其特有的优点,本文拟就多路选择器扩展应用于多输入逻辑设计作一简要介绍。
Digital logic simplification is an important issue in digital systems. Classical methods use Boolean algebra and Karnaugh map simplification. Though modern can use computer-aided logic synthesis, in a typical digital device, manual Karnaugh map simplification However, it is difficult to handle in the case of multivariate (more than 5, 6 variables). Therefore, how to give full play to the advantages of existing large-scale devices with high integration and extend their logical functions for common use Combinatorial Logic and Sequential Logic Network Synthesis in Digital Systems. Multiplexers in dealing with this kind of problem, has its own unique advantages, this article intended to be applied to multi-input multiplexer to expand the design of multi-input logic for a brief introduction.
