ADDRESS RESOURCE ALLOCATION METHOD AND STORAGE

摘要

Disclosed is an address resource allocation method. A device number and a function number of peripheral component interconnection (PCI) devices as well as the number and type of the PCI devices are acquired (101); when the acquired device number and function number of the PCI devices are the same as pre-stored device number and function number of PCI devices, it is queried whether the acquired number and type of the PCI devices are consistent with pre-stored number and type of the PCI devices (102); and if the acquired number and type of the PCI devices are consistent with the pre-stored number and type of the PCI devices, address resources are allocated to the PCI devices according to pre-stored base addresses required to be allocated to the PCI devices (103). With the method, it is unnecessary to inquire how many address resources are required by PCI devices and wait for the PCI devices to reply before allocating the address resources upon each power-up, so that the power-up time can be reduced and system start-up can be accelerated.
