| Abstract: | Clock synchronization is one of the key techniques of distributed system.In order to construct a distributed measurement system by measuring instrument based on ARM-WinCE platfom,the principle of IEEE1588 precision time protocol is introduced,and a scheme is proposed to implement clock synchronization based on ARM-WinCE embedded system platfomby using DP83640 Ethernet PHY transceiver which supports the IEEE1588 protocol in hardware.The design of hardware interface circuit and framwork of software is given.The designed system is tested and the result shows that the accuracy is better than 1μs. |
