区块消除之装置与方法;APPARATUS AND METHOD FOR TILE ELIMINATION

摘要

依据本揭露的实施范例提供一种区块消除的方法，读入一新的区块资讯；从特征值储存模组读出先前画面之新的区块特征值；区块引擎从新的区块产生特征值，注意的是，从特征值储存模组读出之特征值为先前画面之相同区块，而区块引擎产生之特征值为目前画面之相同区块。一区块比对单元比对相同区块所读出之特征值和产生之特征值是否相同；当比对之特征值相同时，将直接从画面暂存记忆体作相同区块的复制；也就是说，可节省此区块绘制计算量。反之，特征值储存模组将更新取代先前存储之特征值，也就是绘制此区块，继续一后续绘图程序；最后更新画面暂存记忆体中新的绘图区块。; 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.
