摘　　要：为解决分时操作系统下PCI总线测试仪器存在的实时性差、稳定性差、控制过程复杂等问题,研究了采用实时操作系统VxWorks进行PCI总线模块驱动开发的方法。结合VxWorks中设备驱动的特点,采用标准化设计思想,对驱动进行开发、封装和整合。实验结果表明,该设计可以有效地实现VxWorks环境下PCI总线设备的控制和调用,满足驱动程序的功能要求。PCI bus test instrument based on time-sharing operating system has certain disadvantages,such as poor real-time character and stability,as well as complicated control process.To solve these problems,the development of a PCI module’s driver using VxWorks,which is a real-time operating system in this paper investigated.Combining with the characteristics of device drivers in VxWorks,a standardized design method is adopted to develop,pack,and integrate the driver of the module.Experimental result implies that this design can realize the control of the PCI module in VxWorks effectively,thus meet the functional requirements of the driver.
