COMPUTER AND CONTROL METHOD FOR CONTROLLING COMPUTER

摘要

This computer includes: a multi-core processor having multiple processor cores; a memory; and firmware. The processor cores include: an execution mode for switching between a first mode in which an application or an operating system is executed and a second mode in which processing is executed by the firmware in response to a predetermined interrupt; and a power-saving function for setting one of a power-saving-enabled mode in which the power consumption of the processor cores is reduced and a power-saving-disabled mode in which the processor cores are caused to operate at or higher than a rated power thereof. Upon receipt of the predetermined interrupt to the processor cores, core processors to be operated in the power-saving-disabled mode are selected from among the multiple processor cores, and the selected processor cores are caused to transit to the second mode in order to cause the processing by the firmware to be executed.
