Abstract
An electronic apparatus has a normal mode and an energy saving mode for reducing power consumption, and includes a main control unit, a sub control unit, a main storage unit, and a sub storage unit. The sub control unit includes a processing unit performing a part of an update process by storing software update data in the sub storage unit when a software update request is received during the energy saving mode. The main control unit includes a processing unit performing a rest of the update process by moving or copying the software update data from the sub storage unit to the main storage unit and by updating software stored in the main storage unit with the software update data after the electronic apparatus returns from the energy saving mode to the normal mode.
Claims15
An electronic apparatus having a normal mode and an energy saving mode for reducing power consumption, comprising:
- a main control unit controlling the electronic apparatus;
- a sub control unit operating during the energy saving mode;
- a main storage unit being managed by the main control unit;
- and
- a sub storage unit being managed by the sub control unit, wherein
- the sub control unit includes
- a processing unit performing a part of an update process by storing software update data in the sub storage unit when a software update request is received during the energy saving mode;
- and
- the main control unit includes
- a processing unit performing a rest of the update process by moving or copying the software update data from the sub storage unit to the main storage unit and by updating software stored in the main storage unit with the software update data after the electronic apparatus returns from the energy saving mode to the normal mode.
A software update method performed by an electronic apparatus having a normal mode and an energy saving mode for reducing power consumption,
- the electronic apparatus comprising:
- a main control unit controlling the electronic apparatus;
- a sub control unit operating during the energy saving mode;
- a main storage unit being managed by the main control unit;
- and
- a sub storage unit being managed by the sub control unit,
- the software update method comprising the steps of:
- performing, by the sub control unit, a part of an update process by storing software update data in the sub storage unit when a software update request is received during the energy saving mode;
- and
- performing, by the main control unit, a rest of the update process by moving or copying the software update data stored in the sub storage unit to the main storage unit and updating software stored in the main storage unit with the software update data after the electronic apparatus returns from the energy saving mode to the normal mode.
A computer-readable storage medium having a program stored therein for causing an electronic apparatus having a normal mode and an energy saving mode for reducing power consumption to perform a software update method,
- the electronic apparatus comprising:
- a main control unit controlling the electronic apparatus;
- a sub control unit operating during the energy saving mode;
- a main storage unit being managed by the main control unit;
- and
- a sub storage unit being managed by the sub control unit,
- the software update method comprising the steps of:
- performing, by the sub control unit, a part of an update process by storing software update data in the sub storage unit when a software update request is received during the energy saving mode;
- and
- performing, by the main control unit, a rest of the update process by moving or copying the software update data stored in the sub storage unit to the main storage unit and updating software stored in the main storage unit with the software update data after the electronic apparatus returns from the energy saving mode to the normal mode.
