摘　　要：针对基于VxWorks嵌入式系统的SpaceWire设备驱动的设计与实现展开研究;在分析操作系统层次结构和设备驱动调用关系的基础上,对基于VxWorks嵌入式系统的SpaceWire设备驱动框架结构设计,提出了通过操作系统的扩展模块调用SpaceWire总线驱动程序的设计理念;并按开发流程对SpaceWire设备驱动实现的细节进行了分析;其设计理念不仅可以为VxWorks嵌入式实时操作系统开发者在编写各类外设驱动程序时提供参考和借鉴,而且对于其它类似外设驱动程序的设计与实现具有一定的普遍性、适用性和指导性;结合相关具体的应用,证实所开发的SpaceWire总线驱动软件在可靠性和实时性方面都能满足应用要求。This is a research for SpaeeWire device driver design and implementation of VxWorks--based embedded system. On the basis Of analysis of the operating system hierarchy and the device driver calling relationships, for SpaceWire device driver framework structural de- sign of VxWorks--based embedded systems, a design concept is put forward that the expansion module of the operating system calls SpaceWire bus driver program, at the same time, the implementation details of SpaceWire device driver are analysed according to the develop- ment process. The design concept can not only provides a reference for VxWorks embedded real--time operating system developers when they program various types of peripheral drivers, but also has a certain universality, applicability and guidance for the other similar the design and implementation of the peripheral drivers. The related specific application confirmed that the SpaceWire bus driver software could meet the reliability and real--time application requirements.
