基于Windows的VxD和WDM驱动程序的设计

在开发微型计算机应用系统的过程中,通常会遇到在Windows环境下对具有特定功能的硬件设备进行直接访问及控制的问题,开发设备驱动程序是设计计算机硬件设备的科研开发人员必须面临的问题.对工业控制中基于Windows95/98的VxD驱动程序和基于Win-dows98SE/2000/XP的WDM驱动程序进行了比较,并研究了VxD驱动程序和WDM驱动程序在设计中各自需要注意的关键问题.最后以基于PCI总线的DSP板为例,设计了其基于Windows的驱动程序,实现了在Windows环境下HOST对DSP板的控制及数据的传输.

Design of VXD-driver and WDM-driver based on Windows

In the development of micro-computer applications course,direct access and control of hardware equipment with a specific function in the Windows environment are usually encountered,so the design of equipmentdriver must be faced for the scientists and researches who design computer hardware equipment.This article compared the VxD-driver based on Windows95/98 and the WDM-driver based on Windows98SE/2000/XP in industrial control,and studied the key issues in the design of VxD-driver and WDM-driver.Finally the driver based on the Windows of a DSP control board based on the PCI bus is developed by using DRIVERWORKS in the DRIVERSTUDIO driver development kit to achieve the control of HOST on DSP boards and data transmission based on the driving procedures in the Windows environment.
