Abstract
An image forming apparatus includes a main control unit including a plurality of control units, and a sub control unit configured to respond to a request from an information processing apparatus via a network in substitution for the main control unit when the main control unit is being operated in a power saving state, wherein, in a case where the sub control unit receives a request to which the sub control unit cannot perform proxy response from the information processing apparatus, the main control unit determines a number of the control units for responding to the request among the plurality of control units and returns from the power saving state to a normal state using the control units the number of which is determined.
Claims16
An image forming apparatus comprising:
- a multi-core CPU including a plurality of cores;
- a receiving unit configured to receive a packet transmitted by an external apparatus on a network;
- a shifting unit configured to shift a mode in which the image forming apparatus is operated from a first power mode, in which power is not supplied to the multi-core CPU, to a second power mode, in which power is supplied to the multi-core CPU, in a case where the packet received by the receiving unit is a specific type of packet;
- and
- a determining unit configured to determine, out of the plurality of cores included in the multi-core CPU, a number of cores to operate based on the specific type of the packet received by the receiving unit in a case where the shifting unit shifts the mode in which the image forming apparatus is operated from the first power mode to the second power mode.
An image forming apparatus comprising:
- a multi-core CPU including a plurality of cores;
- a receiving unit configured to receive a packet transmitted by an external apparatus on a network;
- a shifting unit configured to shift a mode in which the image forming apparatus is operated from a first power mode, in which power is not supplied to the multi-core CPU, to a second power mode, in which power is supplied to the multi-core CPU, in a case where the packet received by the receiving unit is a specific type of packet;
- and
- a determining unit configured to determine, out of the plurality of cores included in the multi-core CPU, a number of cores not to operate based on the specific type of the packet received by the receiving unit in a case where the shifting unit shifts the mode in which the image forming apparatus is operated, from the first power mode to the second power mode.
A method of controlling an image forming apparatus, the image forming apparatus having a multi-core CPU including a plurality of cores, the method comprising:
- receiving a packet transmitted by an external apparatus on a network;
- shifting a mode in which the image forming apparatus is operated from a first power mode, in which power is not supplied to the multi-core CPU, to a second power mode, in which power is supplied to the multi-core CPU, in a case where the packet received is a specific type of packet;
- and
- determining, out of the plurality of cores included in the multi-core CPU, a number of cores to operate based on the specific type of the packet received by the receiving unit in a case where the shifting unit shifts the mode in which the image forming apparatus is operated from the first power mode to the second power mode.
A method of controlling an image forming apparatus, the image forming apparatus having a multi-core CPU including a plurality of cores, the method comprising:
- receiving a packet transmitted by an external apparatus on a network;
- shifting a mode in which the image forming apparatus is operated from a first power mode, in which power is not supplied to the multi-core CPU, to a second power mode, in which power is supplied to the multi-core CPU, in a case where the packet received is a specific type of packet;
- and
- determining, out of the plurality of cores included in the multi-core CPU, a number of cores not to operate based on the specific type of the packet received by the receiving unit in a case where the shifting unit shifts the mode in which the image forming apparatus is operated, from the first power mode to the second power mode.
