A method and apparatus for video motion compensation, power of two reduction and color format conversion is disclosed. The motion compensation engine performs the MPEG-2 functions of half pel compensation, inverse discrete cosine transform and merge. Dual prime, field-based and frame-based macroblocks are supported. Data reduction may be performed in the vertical direction, the horizontal direction, or both.

According to one embodiment of the present invention, a method of power management for a flat panel display is disclosed. The method includes: receiving image data; determining a segment mode for the received image data; selecting a portion of the received image data corresponding to the determined segment mode; accumulating a value of the selected portion of the received image data; comparing the accumulated value to a threshold value; and generating an interrupt signal if the accumulated value exceeds the threshold value.

Real-time dynamic design of liquid crystal display (LCD) panel power management through brightness control

In one embodiment of the invention, an integrated device is described that employs a mechanism to control power consumption of a graphics memory controller hub (GMCH) through both voltage and frequency adjustment of clock signal received from a clock generator. The GMCH comprises a graphics core and a circuit to alter operational behavior, such as the frequency of a render clock signal supplied to the graphics core. The circuit is adapted to monitor idleness of the graphics core and reduce a frequency level of the render clock signal if the idleness exceeds a determined percentage of time.

Power management for an integrated graphics device

A method and apparatus for enabling power management of a flat-panel display is described. In one embodiment, a method involves detecting at least one display device power state and adjusting a backlight brightness in a display monitor in response to the detecting the at least one display power state. In one embodiment, a method further involves altering the brightness of a display image in order to maintain a display image quality when the backlight is adjusted.

Idle frames received by a graphics controller are compressed by evaluating two idle frames to create an encoding table used to replace selected pixel byte values in subsequent idle frames with codes. Possible pixel byte values are associated with a first set of counters, with each counter counting several different byte values as they occur with the first idle frame. A first subset of the possible pixel byte values is selected based on the counts in the first counters and each byte value in the first subset is associated with a second counter. The occurrences of the first subset of pixel byte values are counted in the second idle frame, and a second subset of pixel byte values is selected based on the counts in the second counters and used to create the encoding table. In one aspect, the encoding table is created when the second set of pixel byte values satisfy a threshold.

An apparatus for image contrast modulation includes a memory for storing a scaling factor and a memory for storing a pixel position. A pixel determiner calculates the position of another pixel based upon the pixel position and the scaling factor. A segment determiner ascertains which segment of the segmented line contains the pixel position. A coefficient generator determines which coefficient is associated with the line segment. A method for image contrast modulation includes defining at least one multi-segmented line that approximates a higher order curve including more than one pixel in a source image, and line-fitting pixel intensity values in a scaled image according to a multi-segmented line.

A method and apparatus for reducing video data. The apparatus is composed of a plurality of reducers. A block is received, corresponding to a plurality of color space components and having a width defined by a plurality of pixels digitally represented by bytes. The video data is first reduced by performing power of two reduction. This is followed by fine scale reduction to achieve the final reduced image.
