Information processing device, control method for same, and program

A computer-implemented method comprising:

• controlling, by a bus controller of n integrated circuit, communication using a bus;
• transiting, by the bus controller of the integrated circuit, according to any one of multiple states including (i) an active state in which communication is capable of being performed, and (ii) a power saving state in which communication is restricted;
• recording, by a monitoring circuit, history data relating to the communication using the bus at a prescribed time interval;
• inferring, by the integrated circuit, whether or not communication will occur at a future inference target time point based at least on the communication history data that is recorded by the monitoring circuit;
• and
• causing, by the integrated circuit, a bus controller to transit to the active state when a result of the inference indicates that communication will occur at the future inference target time point.

A non-transitory computer-readable media that stores instructions which, when executed by one or more processors, causes the one or more processors to perform operations comprising:

• controlling, by a bus controller of n integrated circuit, communication using a bus;
• transiting, by the bus controller of the integrated circuit, according to any one of multiple states including (i) an active state in which communication is capable of being performed, and (ii) a power saving state in which communication is restricted;
• recording, by a monitoring circuit, history data relating to the communication using the bus at a prescribed time interval;
• inferring, by the integrated circuit, whether or not communication will occur at a future inference target time point based at least on the communication history data that is recorded by the monitoring circuit;
• and
• causing, by the integrated circuit, a bus controller to transit to the active state when a result of the inference indicates that communication will occur at the future inference target time point.
