Abstract
A downstream portof a bridgeconnecting a processor unit and a peripheral device acknowledges access from the peripheral device via one of a plurality of downstream channels available for access by the peripheral device to a memory of the processor unit, the downstream channels being virtual channels provided for interfacing with the peripheral device. The routerroutes the access to upstream channels each assigned a memory bandwidth available for access to the memory, the upstream channels being virtual channels supported by the processor unit. In this process, the router refers to a table storing identifiers of the downstream channels and identifiers of the upstream channels in association with each other so as to allocate to the peripheral device the upstream channel corresponding to the downstream channel used by the peripheral device, in response to the access from the peripheral device.
