Data processing system and method for selecting a scope of broadcast of an operation by reference to a translation table

A data processing system includes at least first and second coherency domains coupled by an interconnect fabric. A memory coupled to the interconnect fabric includes an address translation table having a translation table entry utilized to translate virtual memory addresses to real memory addresses. The translation table entry also includes scope information for broadcast operations targeting addresses within a memory region associated with the translation table entry. Scope prediction logic within the first coherency domain predictively selects a scope of broadcast of an operation on an interconnect fabric of the data processing system by reference to the scope information within the address translation table entry.
