Abstract
In one embodiment of the present invention, a system for displaying images in at least one display window on a display unit includes a display processor configured to generate graphics commands from a received input. A graphics processing unit is coupled to the display processor and includes rendering engine configured to generate graphic data from the graphics commands, an internal memory coupled to the rendering engine, and a general purpose I/O coupled to the rendering engine and configured to transmit messages from the graphics processing unit. A graphics logic device is coupled to the graphics processing unit. The graphics logic device is configured to initiate a transfer of graphic data for an update of a display window from the internal memory to the display unit upon receipt of a message indicative of an available update to the display window. An external memory is coupled to the graphics logic device and the external memory is configured to supply graphic data to the display window when the update of the display unit is not available and to store the update of the display window when the display window receives the update from the internal memory.
