Abstract
A resource domain controller in a data processing system stores information that is used to group various resources, such as bus masters and peripherals, into common domains. Each group can be referred to as a resource domain and can include one or more data processor and peripheral devices. The resource domain information is then used to determine whether a particular access request from a data processor is authorized to access its intended target, e.g., one of the peripheral devices, by determining whether the access request and the intended target each belong to a common resource domain. If so, the access request is allowed, otherwise the access request is prevented from being successfully completed.
