实时操作系统工业标准ITRON的分析

The analysis of the RTOS industry standard ITRON

操作系统(OS)技术规范差别之大及实用微控制器品种之繁多,使RTOS(实时操作系统)的标准化成了一个大问题。Industrial TRON(the RTOS Nucleus,实时操作系统中心)组织制订嵌入式系统RTOS的标准。本文对ITRON做了总体介绍并详细研究分析了ITRON的任务状态及任务调度机制。

There are so many kinds of Operating System technology standards and micro controller and processor, which make the standardization of RTOS a very problem. Further more, the lock of hardware resource in low - class micro controller also make the software development a hard problem. The Industrial TRON （the RTOS Nucleus） which also known as ITRON in Tokyo start the establishment of RTOS standard. This article will give a total introduction of ITRON standard and analysize some important details of the task state and scheduling rules of ITRON.
