基于μC/OS-Ⅱ中断返回指令的任务切换设计

Using μC/OS-Ⅱ to Switch the Missions by Intermitting Return Statement

μC/OS-Ⅱ是一个源码公开的占先式多任务实时嵌入式操作系统,可移植性强。通过对在80x86和MCS-51上移植实例的分析,给出了在移植μC/OS-Ⅱ系统时通过中断指令实现任务切换的方法,解决了移植的核心问题。

μC/OS-Ⅱ is an exoteric sound code real time embed operating system. One of its characteristics are doughty transplant. This article exceeds how to use intermit injunction to switch tasks by analysing migrate instance between 80 ＊ 86 and MCU - 51, and to solve the core problem.
