摘要： A memory device for storing a plurality of macroblocks may include a plurality of memory banks. Each macroblock may include m*n pixel data, wherein m is a positive integer, and wherein n also is a positive integer. The plurality of memory banks is adapted to store the pixel data, and wherein each memory bank is sized to store rows of m pixel data. An image processing system may include: a memory adapted to store a plurality of macroblocks; and a video codec. The memory may include a plurality of memory banks. Each memory bank may be sized to store rows of m pixel data. The video codec may be adapted to encode pixel data read from the memory. The video codec also may be adapted to decode the pixel data read from the memory.

摘要： There is provided a media access controller with a power-save mode. Particularly, the media access controller of the present invention minimizes power loss by disabling clocks applied to all blocks, including CPU, of the media access controller during the power-save mode. The media access controller of the present invention includes: a power-save master for securing stable transmission/reception of data through bus by respective processors contained in the controller; a wake-up timer for noticing that the power-save mode is expired; a power control unit for determining whether to supply a power to a phase-locked loop, and a timing when clocks for the media access controller are applied and disabled; and a locktime register for storing a locktime when an output of the phase-locked loop is settled. Additionally, there is provided a method of efficiently changing the media access controller from the active mode to the power-save mode, and vice versa.

摘要： In a clock switching apparatus, a corresponding mask clock signal is generated for at least one of first and second clock signals. A mask clock signal has an interval of a predetermined logical level near the switching between the clock signals. Each mask clock signal is synchronized to the first and/or second clock signals. Such an interval in the mask clock signal prevents occurrence of glitches in an output clock signal that is switched between at least one mask clock signal and/or at least one clock signal.
