Abstract
A control device according to embodiments comprises a data-copying unit, a data-processing instructing unit, and a power-control unit. The data-copying unit copies data in a first memory to a second memory of which power consumption is less than power consumption of the first memory. The data is to be processed at a first data processing unit. The data-processing instructing unit instructs the first data processing unit to process the data copied to the second memory. The power-control unit switches power for the first memory from a first power to a second power while the first data processing unit is processing the data copied to the second memory. The first power is power supplied to the first memory at a time when the data is copied from the first memory to the second memory. The second power is lower than the first power.
