Abstract: There is provided a graphics processor that allows decompression of a compressed texture with high efficiency. The graphics processor includes: a main memory; and a graphics processing unit, in which the graphics processing unit includes a run length decoding section adapted to run-length-decode a compressed texture, and a reciprocal spatial frequency conversion section adapted to restore the texture by performing reciprocal spatial frequency conversion on the run-length-decoded texture, and the main memory includes a texture pool adapted to partially cache the restored texture.
