<p>A method of storing pixel data in a memory of a predictive video decoder (100) that stores pixel data in data words that contain blocks of pixel information. Each data word or a sequence of data words contains pixel data from, for example, a rectangular block of pixels, e.g., a 2 X 2 pixel block is stored in a 4 byte word or a 2x4 pixel block is stored in two successive 4 byte words. These data words are stored in memory pages where a page or successive pages contain a series of words of data representing a row of pixel blocks. Consequently, the data words representing groups (blocks) of pixels are stored from left to right in the order that the pixels appear in the frame. A pair of memory banks (130A, 130B) is used to store the data words and each successive row of pixel blocks is stored in a different one of the two memory banks. Any remaining storage space is used for other purposes than storing video data.</p> |
