摘要
对嵌入式系统的现状、发展和一些重要的概念做出表述。指出了μC/OS-II的缺点:尽管它可用于各类单片机,在诸多领域得到广泛的应用,但是它只能支持固定优先级的64个就绪任务,对于不断出现新的更加复杂的实时系统,往往满足不了需求。文章的创新点在于:在对μC/OS-II任务管理进行系统分析的基础上,提出了采用优先队列扩展其任务管理的方案,并给出了实现这种方案的具体方法。
Firstly,the paper describes the status, the development and some important conceptions of Embedded Operating System. Although μC/OS-Ⅱ can be used for various single chips and it has been used widely in many domains,it can only support 64 ready tasks of fixed priorities. It is not sufficient for new complicated real time systems. The following is what is creative in this paper： This paper introduces a new method to extend its ready task number. The new method uses the data structure of priority queue,thus to make it support more ready tasks and set its task scheduling more flexible.
