摘要
在嵌入式系统应用领域,软件代码日益复杂,但存储器、定时器等硬件资源相对有限。本文设计了一种在硬件资源紧张的情况下提供软定时器的算法。该算法不需要引入操作系统的支持,可以向多任务系统提供足够多的定时服务,并且不影响中断处理时间。
Code is becoming more and more complex in the application field of embedded systems. Some hardware resources such as memory and timer are limited. This paper aims to study and implement an algorithm of soft timer. The algorithm supports multiple soft timers and does not affect the time to process interrupts under the limited hardware and the supporting circumstance without the operating system.
