Abstract: “Linux on ITRON” is the architecture of hybrid operating system, which is to combine the Linux with a ITRON-specified real time operating system. The motive is to reuse the software in Linux environment and keep the existed ITRON-specified real time operating system from large modification. This article evaluates the basic architecture of “Linux on ITRON” described in that article, and presents a new architecture, which can solve the problem of missing of interrupt for Linux in the old architecture, and gives an implementation under the new architecture.

Key words: Operating system, Real-time OS, Embedded system, ITRON

摘要： “Linux on ITRON”是一个正在研究的混血操作系统结构，该结构把Linux与符合ITRON规范的操作系统相结合。目的是有效地复用已经存在的Linux环境的软件，同时又能将系统在符合ITRON规范的操作系统移植。该文对此结构进行了评价，并针对该结构下Linux中断丢失问题对系统结构进行了改进，给出了新结构下解决该问题的实现方法。
