Abstract: Power demand reduction for image generation for displays skips rendering of frames that are highly similar based on a comparison of certain parameters associated with draw calls. A first set of draw calls is received from a game engine by a central processing unit (CPU) circuit and then a second set of draw calls are provided to the CPU circuit. The CPU circuit compares the second set of draw calls to the first set of draw calls. If there is a change in at least one parameter that exceeds a threshold, then the CPU circuit sends the second set of draw calls to a graphics processing unit (GPU) circuit for rendering. If, however, the change in selected parameters is below the threshold, then the CPU circuit sends an earlier rendered image to the display for presentation to the user, effectively omitting usage of the GPU circuit for that frame.
