METHODS AND SYSTEMS FOR UPDATING A BUFFER

摘要

Methods for conveying timing information across a communication link between a first processor and a second processor are described, wherein the communication link is in hibernation mode, the method comprising: scheduling a time event at the first processor to convey the timing information to the second processor; initiating a link wakeup by the first processor at the occurrence of the time event; and detecting the link wakeup at the second processor, and using the detected link wakeup timing to synchronize the first and second processors with respect to the conveyed timing information.
