    摘要: A method and system for an early Z test in a tile-based three-dimensional rendering is provided. In the method and system for an early Z test, a portion which is not displayed to a user is removed prior to performing a rasterization process, and thereby performing the 3D rendering efficiently. The method includes segmenting a scene into tiles for performing a rendering with respect to a triangle; selecting a first tile of the tiles, which has a tile Z value less than a minimum Z value of the triangle; and performing the rendering with respect to the triangle in remaining tiles excluding the selected first tile of the tiles.

    摘要: A cache memory system using temporal locality information and a data storage method are provided. The cache memory system including: a main cache which stores data accessed by a central processing unit; an extended cache which stores the data if the data is evicted from the main cache; and a separation cache which stores the data of the extended cache when the data of the extended cache is evicted from the extended cache and temporal locality information corresponding to the data of the extended cache satisfies a predetermined condition.
