INFORMATION PROCESSING DEVICE, CONTROL METHOD, AND NON-TRANSITORY COMPUTER-READABLE RECORDING MEDIUM HAVING CONTROL PROGRAM RECORDED THEREON

摘要

An information processing device creates a management table of bridge addresses by allocating the bridge addresses to a plurality of bridges, respectively, and, when detecting one access to one device of a plurality of devices, refers to the management table, performs, based on the management table referred to, cancelling allocation of a bridge address of the bridge addresses and reallocating the bridge address to one or more of the plurality of bridges to enable execution of the one access, and updates the management table in regard to the bridge address cancelled and reallocated. Consequently, the information processing device can simultaneously use bridges the number of which exceeds a predetermined number even when the bridges the number of which exceeds the predetermined number are provided in the information processing device and therefore bridge addresses run out.

主权项

1. An information processing device comprising:
a processor; a plurality of devices; and a plurality of bridges which connects the processor and the plurality of devices, wherein the processor creates a management table managing bridge addresses allocated to the plurality of bridges, when an unallocated bridge address to be allocated to one bridge of the plurality of bridges runs out, cancels allocation of a first bridge address of the bridge addresses allocated to another bridge of the plurality of bridges, reallocates the cancelled first bridge address to the one bridge, and updates the management table in regard to the first bridge address cancelled and reallocated, and when detecting one access to one device of the plurality of devices, refers to the management table, performs, based on the management table referred to, cancelling allocation of a second bridge address of the bridge addresses and reallocating the second bridge address to one or more of the plurality of bridges to enable execution of the one access, and updates the management table in regard to the second bridge address cancelled and reallocated.
