ABSTRACT:
A method and apparatus for accessing a memory for processing moving pictures, which loads data from a frame buffer of an external memory, and uses a motion prediction technique. The method includes the steps of: loading, from the frame buffer, pixels of a relevant block of 8×8 size and extra pixel data necessary for an inter prediction while performing the inter prediction of a block of an 8×8 size following division of a macroblock, storing the pixels of the relevant block size of 8×8 and the extra pixel data in an internal cache memory. The stored pixels of the relevant block size of 8×8 and the stored extra pixel data are used; and then the stored pixels of the relevant block size of 8×8 and the stored extra pixel data stored in the cache memory are re-used during an inter prediction of the relevant block size of 8×8 and sub-blocks.
