Abstract: A display controller includes at least one first power domain configured to receive power according to a type of image data, and at least one second power domain configured to receive power regardless of the type of the image data.

Abstract: A mobile System on Chip (SoC) including a central processing unit (CPU) and an audio out module that includes a buffer and an audio interface. A power mode of the audio out module is controlled separately from a power mode of the mobile SoC so that the audio out module operates when the mobile SoC is in a power down mode.

Abstract: A method of controlling power consumption of a portable device includes monitoring whether the portable device has connected to a docking station; and selecting and executing one of a plurality of power consumption controlling algorithms according to a monitoring result.

Abstract: A first-in first-out (FIFO) memory device includes a main FIFO unit, an auxiliary FIFO unit and a control unit. The main FIFO unit includes first through N-th one-port memories, each of which including M entries, where N and M are integers greater than or equal to two. The auxiliary FIFO unit includes one dual-port memory having M entries.

Abstract: A processor includes an emulator configured to receive an access command from a second memory controller, and a first memory controller configured to control an operation of a memory. The emulator is configured to determine whether the first memory controller is available to perform an operation corresponding to the access command, and transmit a wait signal to the second memory controller upon determining that the first memory controller is not available to perform the operation.

Abstract: An under-run compensation circuit is provided. The under-run compensation circuit is configured to receive a clock signal, data, and an under-run detection signal that indicates whether or not an under-run is occurring. The under-run compensation circuit is further configured to output the clock signal and the data when receiving the under-run detection signal that indicates that an under-run is not occurring. The under-run compensation circuit is additionally configured to output the clock signal and dummy data when receiving the under- run detection signal that indicates that an under-run is occurring.

Abstract: A 3D display engine includes a timing generator circuit configured to receive format information from a 3D display and to responsively generate display timing information, a video image data processor circuit configured to receive and process left and right video image data, a 3D format generator circuit configured to frame-pack the processed left and right video image data and a controller circuit configured to control the video image data processor circuit and the 3D format generator circuit responsive to the display timing information.
