Abstract: The present invention provides a processor including a source generator, a request synchronization signal generator and an output circuit. The source generator is configured to generate image data of a frame. The request synchronization signal generator is configured to generate a request synchronization signal to an integrated circuit only after the source generator generates the image data of the frame completely, wherein the request synchronization signal is used to trigger the integrated circuit to send a synchronization signal to the processor. The output circuit is configured to send the image data of the frame to the integrated circuit only after receiving the synchronization signal generated from the integrated circuit in response to the request synchronization signal.

Abstract: A device generates blended frames, with each blended frame composed of multiple image layers and each image layer composed of multiple regions. The device includes display hardware. The display hardware retrieves a given image layer in a current frame from a memory. Based on at least content hints generated at the display hardware for the given image layer in the current frame, the display hardware makes a determination of whether to skip access to the memory for retrieving each region of each image layer in a next frame that is immediately after the current frame, and accesses the memory for the next frame according to the determination.
