【摘要】 随着Linux操作系统在嵌入式系统方面的应用越来越广泛,关于增强并改进Linux对实时任务支持方面的研究也越来越多。该文通过对Liunx下进程调度的原理、依据以及调度算法、实时调度策略的全面分析,说明了Linux对普通进程和实时进程进行相应处理的过程。同时为了改进Linux对实时任务的支持,提出了一种混合调度算法。更多还原

【Abstract】 With the increasingly wide application of the Linux operating system in the embedded system, more and more efforts are focused on how to strengthen and improve its support of real-time tasks. This thesis illustrates how Linux deals with normal processes and real-time processes respectively through a general analysis of the principle and basis of process scheduling, the scheduling algorithm and the real-time scheduling policy. To improve Linuxs support of real-time tasks, this thesis puts forward a mixing scheduling algorithm.更多还原
