摘要

PROBLEM TO BE SOLVED: To solve the problem that the extension of a compressed texture used to be time consuming.SOLUTION: A graphics processor includes: a main memory 300; and a graphics processing unit (GPU) 200. The GPU 200 includes: a run length extension part 30; and an inverse discrete cosine transformation part (IDCT) 40. The run length extension part 30 executes the run length extension of a compressed texture, and the IDCT part 40 performs inverse discrete cosine transformation to the texture subjected to run length extension to restore the texture. The main memory 300 includes a texture pool for partially caching the restored texture.
