Abstract: An exemplary embodiment describes a method for tile elimination, including: reading in data of a new tile; reading signature values corresponding to the new tile from a signature value repository; generating signature values for the new tile; comparing the read signature values and the generated signature values of the same tile to determine whether the two sets of signature values being identical; when the two sets of signature values being identical, copying the new tile directly from a tile frame buffer without rendering; otherwise, updating the signature value repository with the generated signature values replacing the stored signature values; rendering the tile; and updating the tile frame buffer with the newly rendered tile.

Abstract translation: 示例性实施例描述了一种用于瓦片消除的方法，包括：读取新瓦片的数据; 从签名值库读取对应于新瓦片的签名值; 生成新图块的签名值; 比较读取的签名值和生成的相同瓦片的签名值，以确定两组签名值是否相同; 当两组签名值相同时，直接从瓦片帧缓冲区复制新瓦片而不呈现; 否则，用所生成的签名值更新所述签名值库，以代替所存储的签名值; 渲染瓷砖; 以及用新渲染的瓦片更新瓦片帧缓冲器。
