把一个系统分解成若干小的、易于应用而又彼此相对独立的“碎片”。按照这样的原则所设计的系统不仅使用方便,而且维护和调整的消耗最小。设计实际是一种系统的分解和组合的练习。所谓分解就是把一个问题分解成为若干个比较小的问题,而每一个比较小的问题对应于系统的一个“碎片”。问题是从哪里分解和如何分解?那几方面的问题属于系统的同一部分,那几方面则应分属于系统的不同部分?结构设计按下面两条基本原理回答上述问题。问题中相互密切联系的部分应属于系统的同一“碎片”,也就是说属于同一类的事物应该把它们放在一起。问题中互不联系的部分应属于系统中不同的“碎片”。也就是说不要把本来不属于同类的事物放在一起。多器系统中每一个微处理器可以视为一个完整系统的“碎片”。设计者按照使用要求把这些“碎片”组合起来形成一个有机的整体,使各个“碎片”和谐地动作这就是多器系统设计的任务。
Break down a system into smaller, “fragmented” pieces that are easy to apply and relatively independent of each other. The system designed on this principle is not only easy to use, but also consumes minimal maintenance and adjustment. Design is actually a systematic decomposition and combination of exercises. The so-called decomposition is to break down a problem into a number of smaller problems, and each of the smaller problem corresponds to a “fragmentation” of the system. The problem is where to decompose and how to decompose? Several aspects of the problem belong to the same part of the system, which aspects should belong to different parts of the system? Structural design according to the following two basic principles to answer the above questions. The parts of the problem that are intimately related to each other belong to the same “fragment” of the system, that is to say things belonging to the same category should be put together. The parts of the problem that do not relate to each other should belong to different “fragments” in the system. In other words, do not put things that do not belong to the same category together. Each microprocessor in a multi-processor system can be considered as a “fragmentation” of a complete system. Designers in accordance with the requirements of these “fragments” together to form an organic whole, so that all the “debris” in harmony This is the task of multi-system design.
