  • System and method for processing memory with YCbCr 4:2:0 planar video data format
    Patent number: 6989837
    Abstract: A system and method for processing YCbCr video data stored in a paged memory with reduced page breaks. A method is disclosed for retrieving YCbCr planar video data in 4:2:0 format from paged memory. A page of the paged memory containing Y data is accessed; Y data corresponding to M pixels of video data is then retrieved, where M is a value greater than or equal to two. The retrieved Y data is then stored in a shift register. Similar steps are taken to access, retrieve and store Cb and Cr data. Within the shift register, the Y, Cb, and Cr data is stored as sets of planar video data. The Y, Cb, and Cr data is retrieved from the shift register as a series of pixel data for generating pixels on a video display unit.
