μC／OS-Ⅱ任务调度机制分析及其在ARM7上的移植方案

The analysis of task-scheduling system of μC/OS-II and its porting design in ARM7

对嵌入式操作系统的研究是嵌入式软件开发的重点．也是在嵌入式系统中实施复杂任务的基础。本文分析了源代码公开的嵌入式实时操作系统μC／OS_Ⅱ的任务调度机制,并在此基础上给出了一种基于ARM7TDMI内核的s3c44box芯片上移植μC／OS-Ⅱ的方案。该方案已在开发板上验证并成功运行。

The research of embedded operating system is emphasis of embedded software development, which is also the basic of carrying out complex task in embedded system. This paper mainly analyzes the task scheduling mechanism of an embedded real-time operating system μ/OS-Ⅱ whose source code is open, and offers a method to port μC/OS-Ⅱ to s3c44b0x chip based on one kind of ARM7TDMI core on this base. This method had already been validated on experimental equipment and run successfully.
