Claim 1:
2. The resource address allocation method for PCI device according to claim 1, wherein the process of calculating resource address information of PCI devices with no fixed resource allocation demand in a system on the basis of a dynamic allocation policy according to connection information and resource demand information of PCI bridges and the PCI devices in the system comprises:
constructing a PCI tree structure according to a connection architecture of the PCI bridges and the PCI devices in the system;
scanning the PCI bridges and the PCI devices in the PCI tree structure using a depth-first algorithm, and correspondingly writing device connection information of each traversed PCI bridge and resource demand information of each traversed PCI device into the PCI tree structure; and
calculating the resource address information of the PCI devices with no fixed resource allocation demand on the basis of the dynamic allocation policy according to the resource demand information of the respective PCI devices in the PCI tree structure.
