摘要：
This article mainly describes a new approach to realize precise synchronization between master clock and slave clock. To improve the IEEE 1588 synchronization precision, Kalman filtering algorithm is applied based on the application of Ethernet. Four state machines are used to accelerate the process and improve the accuracy of frequency modulation and phase modulation. Simulation result proves that time precision is improved from sub-microsecond to dozens of nanoseconds.
