摘要
针对网络多媒体系统的实时应用需求,本文对Linux2.4核心的调度机制进行了改造。通过将弱硬实时调度算法、挪用调度算法、反馈调度算法继承到Linux核心调度机制中,提高了核心的实时性能;最后通过实际应用检验了改造后的Linux系统在处理网络多媒体数据时的实时性能。
This paper introduces the improvment of the real-time ability of the Linux 2. 4 kernel. Three algorithms such as the weakly hard real-time scheduling algorithm, the time-stealing scheduling algorithm and the feedback algorithm are reallzed in the Linux kernel. Experiments show that the new Linux system is proved more efficient while processing network and multimedia data.
