【摘要】 对嵌入式实时系统VxWorks中的设备驱动程序开发进行了简要的介绍,讨论了VxWorks操作系统下的I/O系统和设备驱动程序、应用程序之间的关系。另外,结合作者开发PCI9054时统卡驱动程序的实际,讨论了VxWorks下PCI设备驱动程序的框架,并详细介绍了各个模块的具体实现。更多还原

【Abstract】 After making a simple introduction of developing device drivers in the RTOS VxWorks,this paper discusses the relationship among I/O system,device driver and application program.In conjunction with the writer’s work on developing the device driver for PCI9054 time uniform card,it introduces the characters of PCI bus and discusses the main frame of the PCI device driver in VxWorks.In the end it presents the codes of these modules that PCI9054 device drivers have to realize.更多还原
