PROBLEM TO BE SOLVED: To effectively utilize a cache memory.SOLUTION: The cache memory includes a cache memory area, a conversion information storage part, and a conversion circuit. In the cache memory area, a plurality of sets are divided into a plurality of sectors. The conversion information storage part stores conversion information for converting a relative set index in a sector into a set index in the cache memory area about each of the plurality of sectors. The conversion circuit uses sector identification information for identifying a sector to be an access object and the conversion information stored in the conversion information storage part to convert a relative set index in a sector shown by the sector identification information into a set index showing a set in the cache memory area to be accessed by a processor.SELECTED DRAWING: Figure 2 |
