摘　　要：详细探讨了基于RTX系统的PXI总线接口板卡驱动程序的开发,总结出PXI驱动开发的具体流程,提出了针对PLX9054桥接芯片的驱动程序设计框架,阐述了驱动程序中各功能模块的实现方法和技术要点,同时利用共享内存和信号量实现了Windows与RTSS进程间的通信,并通过试验验证RTX系统的通信具有很好的稳定性和可靠性,满足测控系统的要求。RTX-based PXI interface card driver development is discussed in detail. The specific driver development process and the driver design framework for PLX9054 bridge chip are summed up in the article. The implementation methods and technical issues of each functional module in driver program are described. The communication between Windows and RTSS process is realized by shared memory and semaphore. It is proved through some experiment that RTX communication has a good stability and relia- bility to meet the requirement of the control systems.
