摘　　要：介绍实时测频卡的硬件结构及DSP芯片TMS320C6416中PCI接口部分的配置寄存器;简述WDM驱动程序的体系结构和基本原理。重点介绍采用Driver Works工具开发WDM驱动程序的方法;详细分析驱动程序设计过程中:I/O端口和内存的映射与访问,中断处理,以及驱动程序与应用程序之间的通信。实践证明,采用自带PCI接口的DSP芯片可以简化设备PCI接口的软硬件复杂度,降低开发成本,同时与开发工具Driver Works相结合,可以大大加快开发周期,提高开发效率。The hardware structure of instantaneous frequency measurement card and the configuration registers of PCI interface of DSP chip TMS320C6416 are introduced in detail. The architecture and basic principle of WDM driver program are also proposed briefly. The methods of developing WDM device driver program by using DriverWorks are focused on and the key points such as the mapping and the access of I/O port and Memory,the interrupt service program and communication be-tween the device driver program and application program are expounded. Practice proves that adopting DSP based on inline PCI interface can lower the complexity of hardware,software and decrease the cost of development,shorten the period of development and improve development efficiency when combined with DriverWorks.
