摘要
介绍了反射内存的工作原理及其常用的组网方式,基于QNX操作系统采用的微内核结构,给出了QNX操作系统下PCI设备驱动开发的基本流程。使用结果表明,借助于QNX的高实时性和反射内存卡的高传输速率,可实现网内大批量数据的实时传输。
This paper describes the working principle of reflective memory card and common network architecture,and based on micro kernel structure adopted by the QNX operating system,gives the basic flow of the development of PCI device driver under the QNX operating system. The application results show that the high real-time of QNX and the high transmission rate of reflective memory card can realize the real-time transmission of mass data in the real-time network.
