    • A drawing device includes a distinguish unit configured to distinguish figure description information in scene data generated by focusing on each figure allocated in a display screen, for respective tiles included in the display screen, the figure description information including a figure index indicating the figure to be allocated in the tile or a setting parameter to be applied to the figure indicated by the figure index; an aggregation unit configured to aggregate, for the respective tiles, a data size of the figure description information distinguished as corresponding to the respective tiles by the distinguish unit; an address determination unit configured to determine a leading address in a memory area for storing the figure description information corresponding to each of the respective tiles, based on an aggregation result obtained for each tile by the aggregation unit; and a memory write unit configured to sequentially write, in the memory area, the figure description information distinguished as corresponding to the respective tiles by the distinguish unit, starting from the leading address determined for a corresponding tile by the address determination unit, wherein the address determination unit determines the leading addresses in the memory areas corresponding to the respective tiles, so that the memory areas for storing the figure description information corresponding to the respective tiles are arranged in a physical address space in an order of drawing the respective tiles.
    • 绘图设备包括区分单元,该区分单元被配置为针对包括在显示屏幕中的各个图块,通过关注分配在显示屏幕中的每个图形生成的场景数据中,区分图形描述信息,图形描述信息包括指示图形的图形索引 分配在图块中或设置参数以应用于图形索引指示的图形; 聚合单元,被配置为针对各个区块将由所述区分单元区分为与各个区块对应的所述图形描述信息的数据大小聚合; 地址确定单元,被配置为基于聚合单元针对每个瓦片获得的聚集结果,确定用于存储与各个瓦片中的每个瓦片相对应的图形描述信息的存储区域中的引导地址; 以及存储器写入单元,被配置为从所述地址确定单元针对相应拼贴块确定的开头地址开始,将由所述区分单元区分为与所述各个拼贴块相对应的所述图形描述信息顺序写入所述存储区中, 确定单元确定与各个区块对应的存储区中的前导地址,以便按照绘制各个区块的顺序将用于存储对应于各个区块的图描述信息的存储区布置在物理地址空间中。
