Abstract:
One disclosed embodiment includes a method of graphics processing. The method includes receiving an indication to update a current frame on a display. A plurality of graphics command are determined to be associated with a next frame that replaces the current frame. A power-up command is generated based on the received indication, configured to cause GPU hardware to begin an initialization operation. The central processing unit processes the plurality of graphics command. Prior to completely process the plurality of graphics command, a power-up command is sent to a GPU firmware. The GPU firmware initializes the GPU hardware based on the power-up command. The processed plurality of graphics command is also transmitted to the GPU hardware. The GPU hardware executes the processed plurality of graphics command to render the next frame on the display.
