Information processing apparatus and control method
An information processing apparatus includes a first processor that takes plural stages of first power control modes different in first rated power from one another, a second processor that takes plural stages of second power control modes different in second rated power from one another, and a power control unit controls the power consumption of the first processor and the power consumption of the second processor. The power control unit determines a second power control mode based on a first event in which a predetermined state of the first processor continues for a first duration or more, and a second event in which a predetermined state of the second processor continues for a second duration or more.
1. An information processing apparatus comprising:
a first processor that takes plural stages of first power control modes different in first rated power from one another;
a second processor that takes plural stages of second power control modes different in second rated power from one another; and
a power control unit that controls power consumption of the first processor and power consumption of the second processor,
wherein the power control unit determines a second power control mode based on a first event in which a predetermined state of the first processor continues for a first duration or more, and a second event in which a predetermined state of the second processor continues for a second duration or more.
2. The information processing apparatus according to claim 1 , wherein the power control unit determines a second power control mode higher in second rated power as the second duration to continue an operating state in which the second processor operates as the predetermined state of the second processor is longer.
3. The information processing apparatus according to claim 1 , wherein the power control unit determines a second power control mode lower in second rated power as the second duration to continue a stopped state in which the second processor is stopped as the predetermined state of the second processor is longer.
4. The information processing apparatus according to claim 1 , wherein the power control unit determines a second power control mode higher in second rated power as temperature of the second processor as the predetermined state of the second processor is higher.
5. The information processing apparatus according claim 1 , wherein the power control unit determines a second power control mode lower in second rated power as temperature of the second processor as the predetermined state of the second processor is lower.
6. The information processing apparatus according to claim 1 , wherein the power control unit gives priority to transition to a second power control mode with highest rated power among transition destinations according to transition conditions as transition conditions to second power control modes higher in rated power that the state of the second processor satisfies.
7. The information processing apparatus according to claim 1 , wherein the power control unit gives priority to transition to a second power control mode with lowest rated power among transition destinations according to transition conditions as transition conditions to second power control modes lower in rated power that the state of the second processor satisfies.
8. The information processing apparatus according to claim 6 , wherein the power control unit gives priority to transition to a transition destination according to a transition condition to a second power control mode higher in rated power over transition to a transition destination according to a transition condition to a second power control mode lower in rated power among the transition conditions that the state of the second processor satisfies.
9. The information processing apparatus according to claim 1 , further comprising:
a temperature control unit that controls temperature of the information processing apparatus,
wherein the temperature control unit expands an output range of a fan of the information processing apparatus as the first rated power of a first power control mode is higher or as the second rated power of a second power control mode is higher.
10. A control method of an information processing apparatus that includes:
a first processor that takes plural stages of first power control modes different in first rated power from one another; and
a second processor that takes plural stages of second power control modes different in second rated power from one another, the control method comprising:
causing the information processing apparatus to determine a second power control mode based on a first event in which a predetermined state of the first processor continues for a first duration or more, and a second event in which a predetermined state of the second processor continues for a second duration or more.
