定时器是保证通信协议正常运行的基本要素之一。通常通信协议用到的定时器精度要求不高,但对于大型通信系统,定时器数量大,硬件和操作系统提供的定时器不能满足要求。文中提出了一种用软件实现大量定时器的高效快速的方法。
The timer is one of the basic elements to ensure the normal operation of the communication protocol. Usually, the precision of the timer used in the communication protocol is not high, but for a large communication system, the number of timers is large, and the timers provided by the hardware and the operating system can not meet the requirements. In this paper, a fast and efficient method of implementing a large number of timers in software is proposed.
