摘要
为解决微内核技术在小内存CPU芯片中应用受限问题,基于双层裁剪技术,将系统任务裁剪分类,并开辟相应优先级线程进行调度管理,提出了一种利用小线程实现微内核任务调度的方法,实现了微内核技术在模糊电饭煲上的实验应用。试验结果表明:该方法实现简单,系统开销小,可移植性强,稳定性高,可应用于小CPU上的嵌入式系统。
Aiming at realizing micro-kernel technology limitedly used in micro-CPU,classifying and cutting out system tasks based on double-cut technology,managing them by opening corresponding priority dispatching threads,an approach for using small threads was given to realize micro-kernel task scheduling,and the application of micro-kernel technology in fuzzy rice cooker was realized.The research results indicate that the method is simple,small system overhead and portability,high stability,and it can be applied to pocket embedded systems based on micro-CPU.
