Abstract:
1. A method of operating a graphics accelerator comprising: operating a graphics processor to render frames in frame buffer memory at a frame rendering rate that exceeds a frame refresh rate of a display interconnected with said graphics processor; sampling said frame buffer memory at said frame refresh rate to display graphics on said display at said frame refresh rate, wherein at said frame rendering rate, the number of frames rendered exceeds the number of frames displayed on said display; in response to detecting a desired reduced power mode, adjusting under software control, said frame rendering rate of said graphics processor to an adjusted frame rendering rate equal to or less than said frame refresh rate, and rendering graphics to be displayed on said display in said frame buffer memory, at said adjusted frame rendering rate, without adjusting said frame refresh rate; controlling said frame rendering rate of said graphics processor so that idle time of said graphics processor between rendering frames at said adjusted frame rendering rate is controlled.
