Embodiments of an apparatus for implementing a display port interface are disclosed. The apparatus may include a source processor and a sink processor coupled through an interface. The sink processor may be operable to send a synchronization signal to the source processor through the interface. The source processor may be operable, dependent upon the synchronization signal, to send data to the sink processor.

主权项

1. An apparatus, comprising:
a source processor; and a sink processor coupled to the source processor via an interface, wherein the interface includes a primary link, an auxiliary link, and a hot plug detect (HPD) link, and
wherein the sink processor is configured to:receive a timing reference signal;generate a synchronization signal dependent upon the timing reference signal;send the synchronization signal to the source processor via the HPD link; wherein the source processor is configured to:
negotiate one or more component capabilities of the sink processor via the interface; andtransmit data to the sink processor via the interface dependent upon the synchronization signal.
