INFORMATION PROCESSING APPARATUS, MEMORY CONTROL DEVICE, AND DATA TRANSFER CONTROL METHOD

摘要

A nonvolatile memory manages stored data by using physical addresses. By using logical addresses associated with the physical addresses, an arithmetic processing unit outputs a process instruction to be performed on data stored in the nonvolatile memory. On the basis of the process instruction output by the arithmetic processing unit, an access control unit detects an instruction to move the data stored in the nonvolatile memory. An address conversion table control unit stores therein the association relationship between the physical addresses and the logical addresses. When the access control unit detects the instruction to move the data, the address conversion table control unit changes the association relationship such that a logical address at the move destination is associated with the physical address in which the data is stored.

1. An information processing apparatus comprising:
a storing unit that stores therein data and that manages the stored data by using a physical address; a processing unit that outputs a process instruction to process, by using a logical address associated with the physical address, data stored in the storing unit; a detecting unit that detects, on the basis of the process instruction that is output from the processing unit, an instruction to move data stored in the storing unit; and an address changing unit that stores therein an association relationship between the physical address and the logical address and that changes, when the detecting unit detects the instruction to move the data, the association relationship such that the logical address at the move destination is associated with the physical address in which the data is stored.
