Information processing device, and control method and program therefor

A computer-implemented method comprising:

• controlling, by a first bus controller, communication via a first bus that connects a first integrated circuit to a second integrated circuit;
• controlling, by a second bus controller, communication via a second bus that is independent of the first bust and that connects the first integrated circuit to the second integrated circuit;
• and
• when communication via the first bus is unavailable, transmitting, by the second bus controller, data from the first integrated circuit to a second integrated circuit via the second bus

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

• controlling, by a first bus controller, communication via a first bus that connects a first integrated circuit to a second integrated circuit;
• controlling, by a second bus controller, communication via a second bus that is independent of the first bust and that connects the first integrated circuit to the second integrated circuit;
• and
• when communication via the first bus is unavailable, transmitting, by the second bus controller, data from the first integrated circuit to a second integrated circuit via the second bus
