Abstract:
1. An electronic device operable in a low power consumption mode and a higher power consumption mode, said electronic device comprising: a processor; a first graphics subsystem interconnected with graphics memory and in communication with said processor; a second graphics subsystem interconnected with said graphics memory and in communication with said processor; said first graphics subsystem and said second graphics subsystem selectively operable to allow a selected one of said first and second graphics subsystems to render graphics into said graphics memory in response to at least one command from said processor; a display in communication with said graphics memory, to display graphics rendered to said graphics memory; said processor executing processor executable instructions causing said processor to transition said electronic device from said higher power consumption mode in which said second graphics subsystem renders graphics to said graphics memory, to said low power consumption mode, by selecting said first graphics subsystem to render graphics to said graphics memory, deselecting said second graphics subsystem, and placing said second graphics subsystem in said lower power consumption state.
