Abstract: An information processing device, includes a memory; and a processor coupled to the memory and the processor configured to: receive, from each of a plurality of unit devices included in the information processing device, a first output which indicates whether an operation is normal, each of the plurality of unit devices storing a firmware, receive, from each of the plurality of unit devices, a second output which indicates whether update of setting data used for operation management of the information processing device is completed, identify, from among the plurality of unit devices, a specific unit device by using the first output and the second output, and perform the operation management of the information processing device by using the firmware stored in the specific unit device.

Abstract: The first buffers forward data from the first device to the respective corresponding second devices through the respective buses while the second buffers forward data from the respective corresponding second devices to the first device through the respective buses. In response to a simultaneous data transmission request to simultaneously transmit data from the first device to the second devices, the switch controller switches the first buffer into a data-forwarding enable state, and switches the second buffer into a data-forwarding disable state, for simultaneous data transmission from the first device to the plurality of the second devices. The pseudo-response generator generates pseudo-response signals acting as a plurality of response signals that the second devices transmit to the first device as a result of the simultaneous data transmission, and transmits the plurality of the pseudo-response signals to the first device. This configuration achieves simultaneous access to multiple devices.
