<p>The presence of a memory (16) that stores therein virtual bus data (161) representing a virtual bus tree configuration in which some of the routes in the I/O bus system (1) are virtually short-circuited; and a controller (15) that notifies the virtual bus data (161) to a CPU (30) disposed upstream of the I/O bus system (1) makes it possible to operate the power source of the devices on the I/O bus system while the system is active.</p> |
