CONTROL DEVICE, DATA PROCESSING DEVICE, CONTROLLER, METHOD OF CONTROLLING THEREOF AND COMPUTER-READABLE MEDIUM
First Claim
1. A control device comprising:
- a data-copying unit that 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 being to be processed at a first data processing unit;
a data-processing instructing unit that instructs the first data processing unit to process the data copied to the second memory; and
a power-control unit that 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 being power supplied to the first memory at a time when the data is copied from the first memory to the second memory, andthe second power being lower than the first power.

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.

14. A control method executed by a control device for instructing a data processing unit to process data copied from a first memory to a second memory of which power consumption is less than power consumption of the first memory, the method including:
-
copying data processed by the data processing unit from the first memory to the second memory; instructing the data processing unit to process the data copied to the second memory; and switching power for the first memory from a first power to a second power being lower than the first power while the power processing unit is processing the data copied to the second memory, the first power being power supplied to the first memory at a time when the data is copied from the first memory to the second memory, and the second power being lower than the first power.
