基于VxWorks的PCI设备驱动程序设计

Design of peripheral component interconnect device driver based on VxWorks

阵列天线控制系统采用实时操作系统VxWorks,为了实现控制系统计算机与单元天线的通信,在控制系统计算机中采用PCI设备与单元天线通信,并且基于VxWorks实时操作系统开发了PCI设备的驱动程序。主要完成了板级支持包的修改、PCI设备的初始化,以及功能函数的设计。经试验验证,该驱动程序工作稳定可靠,可以应用于控制系统中。

The array antenna control system uses real-time operation system VxWorks,and the control system computer communicates with the unit antenna through peripheral component interconnect（PCI） device.This paper develops a PCI device driver based on VxWorks real-time operation system.The main tasks finished include the modification of board support package,the initialization of device registers and the design of performance functions.The test proves that the driver is stable and reliable,and can be applied in the control system.
