Abstract
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.
