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.

Abstract: A method and system for selecting a route in a wireless network for the transmission of a data packet between wireless nodes in said network using a modified link-state routing algorithm wherein only a limited number of broadcast messages are generated to synchronize the link-state database throughout the wireless network. A subset of nodes called portal nodes within the network are elected to do the broadcasting for the entire network. Each portal node broadcasts an announcement of its identity to all of the wireless nodes. Each wireless node responds to these broadcasts to select one of the portal nodes as its root portal node. It then identifies a unicast route back to its root portal node, and sends a link-state register message to this portal node. These link-state register messages received by each portal node are aggregated by them and are broadcast to each of the wireless nodes for storage.
