Information processing apparatus, control circuit, and control method

A control circuit, comprising:

• a selection unit that selects a logical address from among logical addresses identifying data stored in a storage device including a plurality of storage areas;
• an acquisition unit that acquires a physical address associated with the logical address selected by the selection unit, from a conversion table storing therein the logical addresses identifying data stored in the storage device and physical addresses identifying the storage areas in which the data is stored in association with each other;
• a determination unit that determines, using a predetermined condition, whether the data stored in the storage area indicated by the physical address acquired by the acquisition unit is to be transferred;
• a transfer unit that transfers the data stored in the storage area indicated by the physical address acquired by the acquisition unit to another storage area when the determination unit determines that the data is to be transferred;
• and
• an updating unit that updates the physical address associated with the logical address selected by the selection unit out of the physical addresses stored in the conversion table to the physical address indicating the other storage area.

A computer-readable storage medium having stored therein a control program that causes a computer to execute a process comprising:

• selecting a logical address from among logical addresses identifying data stored in a storage device including a plurality of storage areas;
• acquiring a physical address associated with the logical address selected at the selecting from a conversion table storing therein the logical addresses identifying data stored in the storage device and physical addresses identifying the storage areas in which the data is stored in association with each other;
• determining, using a predetermined condition, whether the data stored in the storage area indicated by the physical address acquired at the acquiring is to be transferred;
• transferring the data stored in the storage area indicated by the physical address acquired at the acquiring to another storage area when it is determined that the data is to be transferred;
• and
• updating the physical address associated with the logical address selected at the selecting out of the physical addresses stored in the conversion table to the physical address indicating the other storage area.

A control method that is performed by an information processing apparatus, the control method comprising:

• selecting a logical address from among logical addresses identifying data stored in a storage device including a plurality of storage areas, using a processor included in the information processing apparatus;
• acquiring, using the processor, a physical address associated with the logical address selected at the selecting from a conversion table storing therein the logical addresses identifying data stored in the storage device and physical addresses identifying the storage areas in which the data is stored in association with each other;
• determining, using the processor using a predetermined condition, whether the data stored in the storage area indicated by the physical address acquired at the acquiring is to be transferred;
• transferring, using the processor, the data stored in the storage area indicated by the physical address acquired at the acquiring to another storage area when it is determined that the data is to be transferred;
• and
• updating, using the processor, the physical address associated with the logical address selected at the selecting out of the physical addresses stored in the conversion table to the physical address indicating the other storage area.
