INFORMATION PROCESSING APPARATUS, SYSTEM, AND INFORMATION PROCESSING METHOD |
| 摘要 |
The apparatus comprises a register, a transferring unit that transfers data stored in a first memory to a second memory, and a calculator that applies a checksum operation to the data being transferred by the transferring unit. When a first mode is set, the calculator transmits the result of the checksum operation to the transferring unit, and the transferring unit transfers the result to the second memory. When a second mode is set, the calculator applies the checksum operation to partial data that is included in the data and has been specified as a target of the checksum operation, and transmits the result of the checksum operation applied to the partial data to the register. |

1. An information processing apparatus, comprising:
a register; a transferring unit that transfers data stored in a first memory to a second memory; and a calculator that applies a checksum operation to the data being transferred by the transferring unit, wherein when a first mode is set,
the calculator transmits a result of the checksum operation to the transferring unit, andthe transferring unit transfers the result to the second memory, and when a second mode that is different from the first mode is set,
the calculator applies the checksum operation to partial data that is included in the data and has been specified as a target of the checksum operation, and transmits a result of the checksum operation applied to the partial data to the register. |
