Abstract:
1. A system for controlling display of a mobile terminal, comprising: a display unit configured to display screen data on a screen of the display unit; and a central processing unit (CPU) comprising: a display interface, an internal memory, an internal data bus coupled between the internal memory and display interface, and a screen output buffer portion included within or coupled to the internal memory and configured to receive and to store screen data, wherein the CPU, display interface, internal memory, internal data bus, and screen output buffer portion are all located on a single integrated circuit chip, the CPU is configured to control output of the screen data stored in the screen output buffer portion directly to the display device along a signal path that passes through the internal data bus and display interface, the screen data is output directly to the display device along said signal path based on one clock cycle of the internal data bus, and wherein writing screen data to the screen output buffer portion and reading screen data from the screen output buffer portion is performed within a single clock cycle of the internal data bus of the CPU.
