Apparatus and method for controlling power consumption of devices performing communications between a processor and I/O devices
First Claim
1. An information processing apparatus coupled to a plurality of input/output devices, the information processing apparatus comprising:
- an arithmetic processing device, including a first processor, configured to perform a computation;
a plurality of communication devices each configured to perform a communication between the plurality of input/output devices and the arithmetic processing device;
a second processor configured to;
determine a communication device having power consumption that is controllable, among the plurality of communication devices, the communication device being determined as a candidate for power consumption suppression when determined to have a connection relationship to another communication device among the plurality of communication devices; and
suppress the power consumption of the determined communication device.
