摘要
本文扼要地介绍了 Win9x操作系统下高速数据采集在采样频率上存在的问题，并提出编制虚拟设备驱动程序（ VxD）进行 Win9x系统下高速数据采集的设计方案。介绍了 VxD程序的运行机理、通讯策略和编制方法，并给出实例框架。
The trouble of applying Win9x as operation system platform of data acquisition is discussed in brief and the way of programming VxD is proposed. The principle of VxD including data communication and programming method is introduced, meanwhile an example is given.
