APPARATUS AND METHOD FOR TILE BINNING

摘要

PURPOSE: Tile binning device and method are provided to reduce an overlap factor and the number of triangles necessary for FG, thereby reducing a memory access number and memory access quantity. CONSTITUTION: When a triangle derived from a geometry processing result does not include an abnormal edge, an overlap test unit(220) performs an overlap test for each edge for the triangle. When the triangle includes the abnormal edge, the overlap test unit arranges three vertexes of the triangle corresponding to a Y-axis value and performs the overlap test for each edge of the triangle. A bin array update unit(230) updates a bin array based on an overlap test result. [Reference numerals] (210) Determination unit; (220) Overlap test unit; (230) Bin array update unit
