本文提供了一种用软件在IBM-PC及其兼容机上获得任意定时间隔时钟中断的方法。该方法无须对原机器硬件作任何改动,可用于微机实时控制系统中,方便地获得任意采样频率。
This article provides a way to use software to obtain arbitrary timed-out clock interrupts on IBM-PC and its compatible machines. The method without any changes to the original machine hardware, can be used in real-time computer control system, easy access to any sampling frequency.
