ACCESS CONTROL APPARATUS AND ACCESS CONTROL METHOD |
| 摘要 |
An access control apparatus includes a processor. The processor is configured to receive an access request for accessing first data. The processor is configured to read consecutive blocks that start with a first block containing the first data from a first storage unit. The processor is configured to load the consecutive blocks as corresponding consecutive pages into a memory area. The processor is configured to invalidate the consecutive blocks in the first storage unit. The processor is configured to write, before the loading, some of first pages held in the memory area into a contiguous empty area of the first storage unit in accordance with an access status of each of the first pages. The access status is whether each of the first pages has been accessed. |
