摘要
混合操作系统方法是一种结合一个通用操作系统和一个实时操作系统的有潜力的方法,该方法能够满足嵌入式系统的实时性要求。一个被称为"ITRON-Linux"的混合操作系统体系结构,是基于μITRON规范的一个实时内核和Linux的结合体。在设计"ITRON-Linux"的过程中,发现ITRON的一些任务一旦执行时间过长,就可能造成Linux错过中断处理请求的问题,这里讨论了它的解决方案。
The hybrid operating system is a combination of a general-purpose operating system with a real-time operating system, which has a promising approach to satisfy the real-time property of embedded systems. This paper describes a hybrid operating system architecture called 'ITRON-Linux,' which is a combination of Linux and a real-time kernel based on the μITRON specification. During the design of 'ITRON-Linux', a problem is found, that is, Linux possibly misses some interrupt requests once some of the tasks for ITRON have long execution time and its solutions are also discussed.
