| 摘 要： | 通过对嵌入式操作系统的多线程机制的理论进行研究与分析,提出了一种应用在嵌入式操作系统中的多线程机制实现方案。方案以多线程机制的理论为基础,建立了多线程机制的实现模型,并以Cortex-M3内核为例,深入的分析了这种多线程机制模型的调度实现方案,以及多线程的创建,切换,延时功能函数的实现。嵌入式操作系统的多线程机制的实现以实际应用为基础,以堆栈溢出为例,着重探讨了多线程机制在实现过程当中需要注意的安全因素。

| Abstract: | A new implement of multi-threads technology in embedded operating system is introduced in this paper,which is developed from traditional theory of multi-threads technology.A model of this new implement of multi-threads is bulit up and then the schedule how to create create,switch and delay multi-threads are deeply analyzed.All these operation is implemented in Cortex-M3 core.The implement of multi-threads technology in embedded operating system is based on practical applications.And the stack overflow actio... |
