Abstract

See full text

Devices and methods for reducing a DPU transfer time to compensate for a delayed GPU render time. After completion of rendering a second frame that follows a first frame, a frame processor determines whether the first frame is currently transferring to a display panel or has already been transferred to the display panel. At least one clock is used with a first set of clock speeds when the first frame is determined to be currently transferring and used with a second set of clock speeds when the first frame is determined to have already been transferred, the second set of clock speeds being faster than the first set of clock speeds. After completion of the transfer of the first frame, the second frame is transferred based on the set of clock speeds.
