  • Fetching pixel data with reduced memory bandwidth requirement
    Patent number: 7471298
    Abstract: A system and method is provided which enables pixel data stored in multiple memory pages to be combined in one data packet, thereby reducing the number of data packets needed to transfer a group of reference pixel data. In one embodiment for reducing the reference data fetch bandwidth, the method as applied to a real-time video decoding system optimally combines pixel data stored in different memory pages, and fits the pixel data into a predetermined number of data packets.

  • Macroblock tiling format for motion compensation
    Patent number: 6614442
    Abstract: A macroblock tiling format method and system for implementing the method during an MPEG decoding process is disclosed. The macroblock tiling format groups picture data samples into tiles, each tile including a combination of luminance and/or chrominance data samples corresponding to a given number of macroblocks. Picture data samples in a tile is mapped to memory locations within a single memory page of a buffer memory which temporarily stores decoded pictures.
