资料介绍

IEEE1588协议是一种基于网络多播技术的精密时钟同步协议,为了提高时钟同步的精度,提出了一种在以太网物理层和MAC层之间的介质无关接口(MII/RMII)处检测同步报文的策略和实现精确时间戳标记方案,在此方案基础上设计和实现了基于FP—GA的硬件时间戳标记电路;设计了相关测试平台,对设计电路进行了测试和验证,测试结果表明设计的时间戳标记电路可以在RMII接口处实时地标记同步报文的收发时间戳,设计达到课题要求,应用性能良好。

IEEE1588 protocol is a precise clock synchronization protocol based on multicast technology. To improve high-precision clock synchronization, a detecting and time--stamping strategy based on IEEE1588 for Synchronous Packet in Reduce Media Independent Interface (RMII) is proposed. On the basis of this program, a hardware timestamp circuit based on FPGA is designed. Relevant test platform was designed and the circuit is tested, in which the test results show that time-stamping circuit can mark time stamp of time messages in RMII immediately and the design meet the subject requirements and have a good application performance.
