Abstract
The system efficiently interfaces with display data using a single-chip module consisting of a Micro-Processor Unit (MPU) and a video CODEC. GUI data and video data are effectively displayed through LCD interfaces, respectively equipped in both of MPU and video CODEC, when two individual chips of MPU and video CODEC are incorporated into a single-chip module. The MPU and video CODEC may each be equipped with their own LCD interfaces. Thereby, GUI data of MPU and decoding video data of video CODEC are transmitted out to an external LCD driver for performing a display. The system for interfacing with display data is available for various multimedia applications, since a display of video CODEC and MPU can be more efficiently and freely performed through the method of data transmission using a LCD interface commonly supported by a MPU.
