摘要
Windows2000操作系统以其良好的性能取代了Windows95和Windows98,广泛出现在计算机应用领域。本文对Windows2000的实时性进行了分析,并针对其在控制领域应用中实时性的不足,提出几种达到精确计时实时控制要求的解决方案,重点介绍了通过对8253定时器直接编程,利用VxD编写中断处理程序实现高精度定时实时控制的方法。
Windows2000 Operation System is widely used in the field of computer application for its excellent property. Thisarticle analyzes the real-time capability of Windows2000, and brings forward some methods for fulfilling the task of precisetiming. Among others, this article mainly talks about the method of setting 8253 by directly programming and programminginterrupt processing by means of VxD(Virtual Device Driver) technique.
