Abstract

Provided are a method and a device for real-time clock synchronization, the method including: creating a configuration task, a synchronization packet task, a follow-up packet task, a delay request packet task, a delay response packet task, and a timestamp update task with the same priority and same time slice; running each task based on the time slice and in a round robin mode; generating a hardware interrupt by timing based on a clock synchronization interval; responding to a hardware interrupt of the timer hardware interrupt, identify a master port for the synchronization packet task, to record the master port with a synchronization identifier in a synchronization port table; detect a synchronization packet sending event and a delay request packet receiving event on the master port, and record synchronization packet timestamp information for updating the synchronization timestamp table and delay request packet timestamp information for updating the delay request timestamp table.
