CACHE MEMORY APPARATUS FOR 3-DIMENSIONAL GRAPHIC COMPUTATION, AND METHOD OF PROCESSING 3-DIMENSIONAL GRAPHIC COMPUTATION

摘要

A cache memory device for 3D graphic computation and a 3D graphic computation processing method are provided to refer to apex index arrangement for more accurately predicting the processing order of apex data used in the 3D graphic computation to improve a cache hit rate although a cache memory of a limited size is used. A cache memory array(411) stores apex data used in 3D graphic computation. A tag memory(412) stores first apex indexes corresponding to the apex data. An index buffer(421) stores second apex indexes associated with the graphic computation according to the processing order of the graphic computation. A cache memory control unit(410) compares the second apex index with the first apex indexes, and judges whether to perform a cache hit of the apex data.
