嵌入式操作系统进程调度研究

Research on Process Scheduling in Embedded Operating System

进程调度是嵌入式操作系统的关键问题，决定了操作系统的优劣。为了深入了解嵌入式操作系统的进程调度技术．针对现有嵌入式操作系统的发展现状，选取较流行的μC／OS-Ⅱ和Linux为研究对象，对它们的进程调度机制和策略进行了研究，指出它们的特点。在相互对比的基础上，提出了相应的改进方案。

Process scheduling is the key problem in embedded operating system, which determines the operating system is good or not. In order to go deep into the techniques of process scheduling in embedded system, under the current developing situation of embedded system, chooses μC/OS-Ⅱ and Linux as examples, researches their scheduling mechanism and scheduling policy, points out their characteristics. By the contrast of each other, brings forward an improved scheme accordingly.
