摘要
在TD-LTE多模基带系统中,不同的网络模式协议时间对定时器的要求有所不同。实时时延处理是通信协议的基本组成部分,直接体现协议的时序关系。而定时又是时延的核心内容,故定时器在通信协议的开发中有着至关重要的作用。本文描述了一种嵌入式系统定时器的实现方法,能有效地减少系统无效中断次数,提高系统效率。
In TD-LTE multi-mode baseband system, different time of network mode protocol has different requirements for timer. Real- time time delay processing is the essential part of the communication protocol, and it directly reflects the relationship of protocol timing. Timing is the core content of time delay, so the timer plays a vital role in communication protocol development. An implementation method of the timer in embedded system is described. It can effectively reduce invalid interrupt numbers and improve system efficiency.
