PROBLEM TO BE SOLVED: To eliminate the trouble that there is the need of preventing the performance of a processor from being degraded owing to occurrence of an interruption. SOLUTION: In the event that an interruption occurs in a PCI device connected to a PCI bus divided by a PCI-PCI bridge, a content of an internal register of the device is mirrored to a storage area of the PCI-PCI bridge. Access is made to the mirrored content for read-accessing the internal register of the PCI device where the interruption occurred from the processor. COPYRIGHT: (C)2005,JPO&NCIPI
