Processor, display driver integrated circuit and control method thereof

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. Correspondingly, the invention also provides a display driver integrated circuit and a control method thereof. 本发明提供了一种处理器，包括源产生器，请求同步信号产生器和输出电路。源产生器被配置为生成帧的图像数据。请求同步信号产生器被配置为仅在源产生器完全生成帧的图像数据之后才向集成电路生成请求同步信号，其中，请求同步信号用于触发集成电路发送同步信号给处理器。
