Abstract: Existing synchronization methods can be inefficient in hardware-assisted implementations because of the effects of various jittery events. Thus, a method and an apparatus are provided to synchronize a slave device's clock to a master device's clock for a hardware-assisted implementation. The method can include the receipt of three messages. Time differences are determined based on a time extracted from two of the messages and a time of receipt of a different one of the messages. The slave device's clock can be adjusted based on these time differences. Thus, this method, which can include a dynamic weighted average to compute and implement the synchronization, can synchronize the clock of the slave device to the clock of the master device in a faster time interval.

Abstract translation: 由于各种抖动事件的影响，现有的同步方法在硬件辅助实现中可能效率低下。 因此，提供了一种方法和装置，用于将从属设备的时钟与主设备的时钟同步以用于硬件辅助实现。 该方法可以包括接收三条消息。 基于从两个消息中提取的时间和接收到不同消息的时间确定时差。 可以根据这些时间差来调整从设备的时钟。 因此，该方法可以包括用于计算和实现同步的动态加权平均，可以以更快的时间间隔将从设备的时钟同步到主设备的时钟。
