PROBLEM TO BE SOLVED: To provide a graphics processor; to provide its processing method and to provide its recording medium. SOLUTION: This graphics processor is provided with: a rasterizer for outputting fragment information while rendering data in an i-th span (i is a natural number); a processor for outputting coordinates calculated by calculating coordinates of the first data in an (i+1)-th span based on the fragment information outputted from the rasterizer; a cache memory for storing data corresponding to the calculated coordinates output from the processor and prefetched from an external memory device. The graphics processor includes: a step for processing data in a current span; a step for storing data corresponding to an address of starting data of the next span in the cache memory by prefetching them from the external memory device based on information related to the data in processing. Accordingly, since a cache mistake occurring every time the span is changed for every triangle can be reduced, the performance of the graphics processor is improved. COPYRIGHT: (C)2007,JPO&INPIT |
