Summary:The invention provides a merging unit, a method for selecting a coverage area merging scheme and a depth test system. Inventive aspects include a binning unit for coarse depth culling during binning of pixel geometries. The binning unit includes a rasterizer to receive primitives, and generates pixel coverage information and depth information. The binning unit includes one or more local culling stages to perform local culling within a window of primitives. The local culling unit outputs a set of surviving coverage and surviving depth information. The binning unit includes one or more global culling stages to use the set of the surviving coverage and the surviving depth information to further cull based on an entirety of previously received coverage information and depth information. 提供一种合并单元、选择覆盖范围合并方案的方法和深度测试系统。发明性方面包括用于像素图形的合并期间的粗略深度剔除的合并单元。所述合并单元包括光栅化器，光栅化器用于接收图元并生成像素覆盖范围信息和深度信息。合并单元包括一个或多个局部剔除级，所述一个或多个局部剔除级用于在图元的窗口内执行局部剔除。局部剔除单元输出幸存覆盖范围信息和幸存深度信息的集合。合并单元包括一个或多个全局剔除级，所述一个或多个全局剔除级用于基于先前接收的覆盖范围信息和深度信息的整体使用幸存覆
