Abstract

See full text

A graphics processing unit (GPU) instructs a display control module to capture content and display captured content in response to the refresh rate of a display exceeding a frame generation rate of the GPU. Rather than re-transmit the same frame multiple times, the GPU instructs the display control module to replay a previously-transmitted frame. During a refresh cycle in which the display control module is replaying captured content, the GPU omits accessing memory to retrieve and resend the frame that is being replayed, and instead sends only invalid data and GPU timing information so that the display control module remains synchronized with the GPU.
