摘要
对Linux内核进行了分析,研究了Linux内核在实时性方面的一些不足,并从开发一套基于ARM9的具体测控系统出发,提出了对ARM平台上的Linux系统时钟粒度、调度方式和中断管理的修改方案,该方案提高了嵌入式Linux内核的实时性。以此为基础,构成了一套多任务测控系统,该系统能够满足测控的实时性要求。
Linux kernel is analyzed, and its deficiency in real-time aspect is studied. And aiming at development of a measurement and control system based on embedded Linux for ARM9, modification scheme about Linux system clock granularity, scheduer and interrupt management are presented. The real-time capability of Linux kernel can be enhanced through the modification. And a multiple-task measurement and control system based on the modification has been realized, which is satified the requirement in real-time capability.
