First and second processing units execute a binary program. A temperature sensor measures a temperature of a first processing unit. A temperature detection unit outputs a first interrupt instruction when the temperature measured by the temperature sensor exceeds a first value. A bus exchanges data between the first and second processing units. In response to the first interrupt instruction, the control unit interrupts execution in the first processing unit, migrates first data that is necessary for resuming the execution of the binary program from the first processing unit to the second processing unit, and controls the second processing unit to resume the execution of the binary program in the second processing unit. A power control unit interrupts power supply to the first processing unit after the first data is migrated to the second processing unit.
