基于ARM9200体系的IEEE 1588硬件实现

Hardware implementation of IEEE 1588 based on ARM9200 system

随着通信技术的发展,通信系统对网络之间的同步精度越来越高,传统的GPS方式以及NTP同步越来越不能满足系统的发展。2004年,安捷伦公司提出PTP(IEEE 1588)同步方式,该方式能达到次纳秒级精度,可满足大型通信网络要求。本文主要分析IEEE 1588的同步机制,并最终以AT91RM9200为核心实现IEEE 1588同步系统。

With the development of communication technologies,the communication systems are getting higher requests for the precision of network synchronization.In 2004,Agilent Technologies introduced PTP （IEEE 1588） synchronization,which can achieve subnanosecond accuracy and meet the requirements of large communication networks.This article analyzes the IEEE 1588 synchronization mechanisms,and using AT91RM9200 as the core technology to realize IEEE 1588 synchronous system.
