摘要

本文介绍了实时系统中基于消息的微内核的基本原语和主要组件的设计与实现，找出了其存在的不足和改进的途径。具有基于消息的微内核的实时操作系统使用户能够轻松地为特定目的添加或更改系统服务。但是由于消息复制和同步，它具有相当大的中断延迟和系统调用开销。为了支持真正的实时性能，需要内核抢占和高效的消息交换机制。

Message-based microkernel for real-time system

This paper describes the design and implementation of the basic primitives and major components of the message-based microkernel for real-time systems to find out its shortcomings and ways to improve them. The real-time OS with message-based microkernel enables a user to add or change the system services easily for special purposes. But it has rather large overhead of interrupt latency and system call due to the message copy and synchronization. In order to support true real-time performance, kernel preemption and efficient message exchange mechanism is required.<>
