Abstract：To meet the requirements of clock synchronization for distributed control systems, anembedded Ethernet communication hardware and software system is designed, which based onhardware-assisted timestamp way to realize the IEEE 1588 Precision Clock Synchronization Protocol. Inthis system, the hardware and software architecture of the clock synchronization module is introducedby great length. The master and slave clock module achieves high-precision clock synchronization inplatform test. In addition, the clock synchronization test results in different synchronous messagetransmission cycle are analyzed and compared.
