Abstract

Abstract: With the development of real-time distributed system，the real time kernel should meet new requirements such as event/time mixed trigger.To minimize the jitter because of the interference of time-triggered activities，an improved schedule of time-triggered tasks is proposed.A new embedded real time kernel named TTuCOSII（Time-Triggered Micro Operating System II） is implemented by adding the time-trigger module to the uCOSII which is an open source operating system kernel.Unlike other real-time kernels，TTuCOSII supports both event trigger and time trigger.Simulation shows that TTuCOSII is of high precision of time-trigger and high performance of scheduling，which fulfills the requirement of event/time mixed triggered system.

Key words: event/time mixed triggered, scheduler, jitter

摘要： 针对分布式实时系统对操作系统内核的新需要，为避免因时间触发任务相互影响而造成的抖动，研究了时间触发任务的调度器设计，提出了一种改进的调度策略；在开放源代码的uCOSII嵌入式操作系统内核的基础上扩展了时间触发功能，设计了支持事件/时间混合触发的嵌入式实时操作内核TTuCOSII（Time-Triggered Micro Operating System II）。仿真实验表明TTuCOSII具有较高的时间触发精度，良好的调度性能，可以满足事件/时间混合触发的要求。
