Implementation and research of hardware time stamping techniques based on IEEE1588

Along with the network control technology development, the distributional control system set a higher request to the clock synchronization precision; Taken the IEEE1588 precision clock synchronization standard as the background, it elaborated the high accuracy clock synchronization mechanism and the principle of clock adjust, has analyzed the core algorithm of IEEE1588 agreement-best master clock (BMC) algorithm, and has proven that the most primary factor that affects the IEEE 1588's synchronization precision is the timer precision, and at last proposed the solution of time stamp based on the DP83640.
