MQX 实时操作系统设备驱动设计研究

摘要

设备驱动是操作系统重要的组成部分。阐述 MQX（Message Queue eXecutive）实时操作系统的设备驱动管理机制，基于对 MQX 统一设备模型的分析，总结出 MQX 设备驱动设计的基本原理和一般方法。结合软件构件技术，提出一种分层驱动的实现模型，通过复用底层驱动构件加速了 MQX 设备驱动的开发。%Device driver is an important part of operating system.The device driver operating mechanism of MQX real-time operating sys-tem is described in this paper.Based on the analysis of the unified device model in MQX,we have summarised the rationale and general method of MQX device driver design.Combined with software component technology,we propose a hierarchical driven implementation model and accelerate the development of MQX device driver by reusing base driver component.
