Waiting Signaling Mechanism

The waiting mechanism implies an event being waited for. The following description uses the Surface Processing signal as an example of the waited event.

The Surface Processing signal occurs when a transfer phase terminates. It is issued by a channel to indicate that the destination memory surface has been filled with an image coming from the source camera, and that this surface is available for image processing (see SurfaceState).

The main application thread has to wait for a specified event to occurs. Subsequently, the image processing task is performed.
