摘要
IEEE1588中定义了网络测量和控制系统的精密时间协议(precision time protocol,PTP)标准,其网络对时精度可达亚μs级。简要分析了IEEE1588协议的时钟同步机制和关键算法。最后对IEEE1588时钟同步协议中一些功能模块的FPGA设计进行阐述,给出了总体模块划分和框图。
IEEE1588 defines a precision time protocol （PTP） for networked measurement and control systems,which supports sys temwide synchronization accuracy in the submicrosecond range.This paper introduces the mechanism of IEEE1588 precision clock synchronization protocol and critical algorithm.Finally,the FPGA designs of module are provided and the frame dia grams of critical modules are also listed.
