In this paper,a method is given which can implement hardware realtime control under the environment of Windows 9x.Based on the structure of Windows 9x kernel and the running mechanism of VDD(Visual Device Driver),a method for controlling turntable in realtime is given.Practices show that this method has many advantages,such as convenience in VDDs' development and powerful in transaction processing capability.%给出了一种Windows 9x环境下实现硬件实时控制的方法.在介绍了Windows 9x内核结构,并阐述了虚拟设备驱动程序的结构和运行的基础上,结合转台控制系统,提出了一种实时控制方法.实践证明:把虚拟设备驱动程序应用于转台实时控制具有开发方便,事务处理能力强等优点.
