摘要
在资源有限的嵌入式系统中,任务调度器的好坏很大程度上决定了系统的性能.本文分析了实时系统中有代表性的静态以及动态调度算法,并总结了各自的优缺点.在此基础之上,对嵌入式实时内核μc/os-II的调度算法进行了优化.
Task scheduler largely determine performance of the embedded system with limited resources. This paper analyses typical static scheduling algorithms and dynamic scheduling algorithms, and summarizes their merits and faults. This paper also optimizes scheduling algorithm of the embedded real-time kernel μc/os-Ⅱ based on these.
