摘要
Abstract
In a distributed system, it is used to need a global time to determine the order of events happened in system, coordinate the various information transmissions in order to control and monitor the operation state, so that the clock synchronization is required to synchronize the every slave subsystem. First, the working principle and process of the IEEE 1588 precision clock synchronization protocol are described, the basic program flow is introduced. Second, the clock synchronization with FTP (precision time protocol) between two devices communication is implemented on the platform of embedded Linux operating system. Finally, the test result shows that the accuracy of synchronization can reach less than tens of microseconds.关键词
