PROBLEM TO BE SOLVED: To improve cache hit ratio.SOLUTION: The cache memory controller (i.e., cache controller) 12 has a count part 22 and a cache control unit 21 to control a set associative cache memory 13. The count part 22 counts the number of rearrangements on each of plural sets on the cache memory 13. The cache control unit 21 adjusts the number of ways in each set based on the number of rearrangements on each set counted by the count part 22.SELECTED DRAWING: Figure 1 |
