Abstract
An information processing apparatus includes a first processing unit, a second processing unit which is different from the first processing unit, a supply unit configured to supply a clock to the first processing unit and the second processing unit, and a control unit configured to control the supply unit in such a manner as to stop a supply of the clock to the second processing unit in response to completion of activation of the second processing unit, and to resume the supply of the clock to the second processing unit in response to completion of activation of the first processing unit.
Claims25
An apparatus comprising:
- a first processing unit configured to control the apparatus;
- a second processing unit configured to execute data processing according to a command issued from the first processing unit;
- a supply unit configured to supply a clock to the first processing unit and to supply a clock to the second processing unit;
- and
- a control unit configured to stop, after a boot of the second processing unit has been completed and before a boot of the first processing unit is completed, a supply of the clock to the second processing unit.
A method for controlling an apparatus including:
- a first processing unit configured to control the apparatus;
- a second processing unit configured to execute data processing according to a command issued from the first processing unit;
- a supply unit configured to supply a clock to the first processing unit and to supply a clock to the second processing unit, and a control unit configured to stop a supply of the clock to the second processing unit, the method comprising:
- and
- stopping the supply of the clock to the second processing unit after a boot of the second processing unit has been completed and before a boot of the first processing unit is completed.
A non-transitory computer-readable storage medium that stores a program for causing an apparatus including:
- a first processing unit configured to control the apparatus;
- a second processing unit configured to execute data processing according to a command issued from the first processing unit;
- a supply unit configured to supply a clock to the first processing unit and to supply a clock to the second processing unit, and a control unit configured to stop a supply of the clock to the second processing unit, to execute:
- and
- stopping the supply of the clock to the second processing unit after a boot of the second processing unit has been completed and before a boot of the first processing unit is completed.
