一种高精度定时器的设计及其应用

Design of a high-resolution timer and its application

随着计算机软硬件技术的发展,计算机控制系统可以达到的精度越来越高。本文介绍了一种基于PentiumCPU的高精度定时方法,在不同主频的CPU下,可获得不同的定时精度,最高可达到10微秒量级。同时,介绍了这种定时方法在某种步进电机控制中的应用。

With the development of computer software and hardware,the control resolution of computer controlled system is higher and higher.This paper presents a kind of high-resolu-tion timer based on Pentium CPU.Working on different main frequency CPU,the correspond-ing timing resolution can be achieved,and the highest one is10uS.The application of the timer in a step motor control is also introduced.
