PURPOSE: To reduce the processing of the rearrangement of a triangle, to reduce a data transfer amount and to perform a high-speed graphic processing even though it is a small scale. CONSTITUTION: A register for sorting is constituted of three vertex 1 register 20, vertex 2 register 2 and vertex 3 register 22 connected on a pipeline for constituting a vertex register 19, an XY comparator 23 and a read selection device 24. Then, when vertex information is written to the vertex 3 register 22, the shape of the triangle is judged by comparing the large/small relation of XY coordinates from the respective vertex registers 20, 21 and 22 in the XY comparator 23. In the read selection device 24, vertexes are rearranged by the judged result and requested data are read. |
