介绍了CompactPCI 总线、接口技术、配置空间的内容和操作方法。详细说明在VxWorks 实时操作系统下配置

CompactPCI 总线设备的方法。硬件中断处理是实时系统设计中的关键问题。该设计将外部中断与中断服务程序连接，

并控制QL5064 PCI 接口的中断控制寄存器。在中断服务程序中使用信号量实现任务间的同步，保证了系统实时数据

采集的可靠性。-CompactPCI bus interface technology, the contents of the configuration space and method of operation. Describe the VxWorks real-time operating system configuration CompactPCI bus equipment. The hardware interrupt handling are key issues in the design of real-time systems. The design of the external interrupt connected to the interrupt service routine and control QL5064 PCI interface interrupt control register. In the the semaphore interrupt service routine task synchronization ensures the reliability of the system real-time data acquisition.
