A cache memory control device according to an embodiment of the present invention comprises: a refill counter that counts a refill request, and a cache-capacity determining unit that determines cache capacity. The cache-capacity determining unit transmits a cache-capacity-decrease command signal to the cache memory when a count value is equal to or smaller than a first threshold value or is smaller than the first threshold value, and the cache-capacity determining unit transmits a cache-capacity-increase command signal to the cache memory when the count value is equal to or larger than a second threshold value, which is larger than the first threshold value, or when the count value is larger than the second threshold value.
