摘要
A peripheral component interconnect (PCI) bridge which interfaces between PCI and local buses to provide a communicator for performing a communication between peripheral devices connected to the PCI bus and system devices connected to the local bus, is provided. The PCI bridge comprising a PCI register which is initialized according to a reset signal from the PCI bus and then stores configuration information on the PCI bus, a local register which is initialized according to a reset signal from the PCI bus and then stores configuration information on the local bus, PCI bus interface logic for performing interfacing according to the configuration information stored in the PCI register, local bus interface logic for performing interfacing according to the configuration information stored in the local register, and a logic transformer for reconstructing the PCI bus interface logic according to a command input from a user.
