Abstract:
1. A graphics controller, comprising: a memory region configured to store image data for display on a display panel in communication with the graphics controller; interface circuitry module, each configured to transmit data from the graphics controller over a set of shared data lines; selection circuitry, including a first multiplexer and a second multiplexer, configured to select data from one of the interface circuitry modules for transmission over the set of shared data lines; and line sharing circuitry configured to inform each of the interface circuitry modules to transmit control data, the line sharing circuitry further configured to generate select signals for the selection circuitry, the select signals enabling the selection circuitry to select the data from one of the interface circuitry modules; and wherein the first multiplexer is configured to select data from one of a plurality of peripheral device modules, and the second multiplexer is configured to select data from one of a display panel interface module and the selected data from the one of the plurality of peripheral device modules.
