Intelligent PCI/PCI-X host bridge |
摘要 |
A PCI host bridge and an associated method of use are disclosed. The PCI host bridge includes a host bus interface, an I/O bus interface, and a PCI operation detection circuit. The host bus interface is suitable for communicating with a host bus of a data processing system and the I/O bus interface is suitable for communicating with a primary PCI bus operating in PCI-X mode. The PCI operation detection circuit is adapted to detect a PCI-X operation from the primary PCI bus that may have issued from a PCI mode adapter coupled to a secondary PCI bus. The detection circuit is further adapted to generate a modified operation for forwarding to the host bus in response to determining that the PCI-X operation may have originated from a PCI. mode adapter.
