Abstract:
1. A graphic processing apparatus which draws pixel data of a plurality of polygons in a frame buffer having a plurality of blocks being divided, comprising: a plurality of chunk buffers each configured to being same size as the block; a chunk assignment unit configured to perform assigning the blocks, in which a target polygon being processed is located, to the plurality of chunk buffers sequentially, until the number of assigned chunk buffers reaches M units, a shape of the plurality of assigned blocks becomes non-rectangular in accordance with the target polygon when the target polygon is located in the plurality of adjacent blocks; a chunk generation unit configured to generate pixel data of the target polygons, the pixel data being located in the blocks assigned to the plurality of chunk buffers, and writes the pixel data to the plurality of chunk buffers; and a chunk writing unit configured to write the pixel data written in the plurality of chunk buffers to the frame buffer, wherein a processing phase, including processing of the assigning by the chunk assignment unit, processing of generating and writing pixel data by the chunk generation unit, and processing of writing pixel data to the frame buffer by the chunk writing unit, is repeatedly executed for the plurality of polygons.
