摘要
具体分析了VxWorks下PCI总线的配置空间结构和地址映射,并采用CPCI9054芯片,结合一个信号产生、数据采集处理系统的工程实例,详细阐述了VxWorks下CPCI设备驱动程序的开发实现方法和具体步骤,并给出了部分关键代码。应用结果表明,该方法可移植性较高,可操作性强,对于了解和开发CPCI驱动程序具有一定的参考价值。
Firstly, the PCI configuration space architecture and address mapping are analyzed, and then, according to a engineering examples used the CPCI9054 chipsets for signal generator and data acquisition, the specific method and steps of developing CPCI device driver for embedded real-time VxWorks system are introduced in detail, and importantly, some key programs is provided. As a result, the technology and methods adopted in this paper are practical and worthy of using abroad. It is very useful for realizing and developing CPCI device driver.
