<P>PROBLEM TO BE SOLVED: To pipeline a prefetch mechanism that provides cache of depth tile in a 3D graphic processing. <P>SOLUTION: A prefetch mechanism can be stored in advance in cache predictively using a triangular geometric information in a previous pipeline step, thereby improving efficiency of memory bandwidth usage. A z value compression technique can be used optionally in consideration of a further reduction of electric power consumption and the memory bandwidth. <P>COPYRIGHT: (C)2012,JPO&INPIT |
