Windows2000设备驱动程序的设计与开发

Design and Implementation of Device Driver Based on Windows 2000

在分析Windows设备驱动模型(WDM)的基本结构、设计和开发等基本问题的基础上,采用WDM技术设计 开发了体外反搏辅助循环装置的软件系统.该系统在临床实验中运行稳定,实现了实时、高速、多通道I/O设备驱 动,较好地满足了系统(用户)对I/O设备的管理.

Based on Windows, it is one of the most difficult work developing I/O device driver of bus structure, such as serial/parallel port, PC-PCI, PC-USB. This paper introduces the basic structure of WDM and analyses the approach to design and develop the device driver effectively taking the design and development of the External Counterpulsation(ECP) device system as an example which covers the available approach of developing device driver. The system of clinical trials is very stable and satisfies the user's demands of management well.
