摘　　要：本文介绍了转速测量的基本原理,并对几种测速方法进行了分析比较,说明了这些方法各自的优缺点。在此基础上,介绍一种基于S3C44B0系列的ARM芯片,引入可调度多达255个任务的嵌入系统合作式调度器,。利用ARM实现电机转速的测量,引入了嵌入系统合作式调度器的概念,开发了可进行多任务实现的可靠应用。还解决了电机转速测量及多种附加功能的实现。实现了转速计算,图形显示等功能。This paper introduced a basic principle of rotate speed measurement , and analysis and compare several methods of measuring rotate speed, explaining merit and shortcoming of the these methods .And also Introduce a Microprocessors base on ARM S3C44B0,and adopt a cooperative dispatcher which can dispatch at most 255 tasks, by a cooperative dispatcher in embedded system, the author builds a reliable multiple tasks＇ application system with ARM7 microcomputer,it solve the rotate speed measurement and realize multiple additional function. and realize the function of rotate speed calculation and graphical display and so on.
