嵌入式操作系统调度机制的研究

Research of embedded operating system scheduling mechanism

近年来提出了一些调度机制的实现方案,但这些方案不能实现由用户来选择调度算法和多算法集成,不能给用户提供统一的用户使用界面。为此,提出了一种新的调度机制,它能够给用户提供统一的使用界面,支持所有的调度算法且隐含实现的细节,使用户更方便地使用各种调度算法。在Linux上进行了实现,给出了主要的数据结构和实现过程,对结果进行了分析。

In recent years, some scheduling schemes were presented, but these schemes could not support for user to choose scheduling-algorithm and muhi-algorithm integration, and could not offer a uniform operating-interface for users. The paper presented a new scheduling mechanism, it could offer a uniform operating-interface, and could support available scheduling algorithms, and could hide the implementing details, and let user use all algorithm conveniently. It realized in Linux, presented principal data-structure and realizing procedure, and gave experimental result and analysis.
