PROBLEM TO BE SOLVED: To provide a technology for speeding up data reading by reducing cache mistake. SOLUTION: A two-dimensional texture cache 400 is commonly used from a plurality of texture units 620 to 6n0, and a portion of the texture data of a main memory 10 is stored. A cache control CPU 200 controls a refill operation from the main memory 10 to the two-dimensional texture cache 400 according to the cache mistakes of the plurality of texture units 60 to 6n0 in order to suppress the generation of thrashing in the two-dimensional texture cache 400. The cache control CPU 200 suppress the generation of the refill operation when the plurality of texture units 620 to 6n0 perform access to the same memory address with a predetermined time difference.
