摘要:
Power management methods for integrated circuits are disclosed. A system core block is disposed in a chip and comprises a central processing unit. A power control block is disposed in the chip and comprises a power management mechanism coupled to a power supply to control the supply of power to the system core block. The power management mechanism outputs a power down signal and stops supply of power to the system core block according to a power saving mode setting signal from the central processor unit and starts the supply of power to the system core block according to a power saving mode release signal.

An exemplary video processing apparatus includes a first detection unit, a second detection unit, a format conversion control unit, and a format conversion processing unit. The first detection unit detects a video format of a video input. The second detection unit detects a display capability of a display device. The format conversion control unit determines whether the video input has a three-dimensional (3D) video format or a two-dimensional (2D) video format by referring to the detected video format, determines whether the display device supports a 3D video format or a 2D video format by referring to the detected display capability, and accordingly generates a control signal. The format conversion processing unit is controlled by the control signal to generate a video output satisfying the detected display capability according to the video input when the video input does not satisfy the detected display capability.

A video processing circuit includes a video generating unit for generating a video output stream, a graphic generating unit for providing a graphical stream, and a communication interface circuit coupled to the video generating unit and the graphic generating unit. The communication interface circuit has a first mode provided for mixing the video output stream and the graphical stream to transmit a mixed video output stream through a channel and a second mode provided for merging the video output stream and the graphical stream to transmit a first merged signal through the channel. In the second mode, the communication interface circuit merges the video output stream and the graphical stream by increasing a working frequency of the communication interface circuit to increase bandwidths of the channel, using positions for transmitting a portion of video control signals in the video output stream to transmit the graphical stream, and compressing the video output stream.
