Abstract: The present invention provides a control method of a processor, wherein the control method comprises the steps of: transmitting image data of a first frame to an integrated circuit, wherein the first frame corresponds to a first frame rate; determining a second frame rate of a second frame next to the first frame; determining if a difference between the second frame rate and the first frame rate belongs to a large scale frame rate adjustment or a small scale frame rate adjustment; if the difference between the second frame rate and the first frame rate belongs to the large scale frame rate adjustment, using a first mode to transmit image data of the second frame; and if the difference between the second frame rate and the first frame rate belongs to the small scale frame rate adjustment, using a second mode to transmit image data of the second frame.

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.
