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

A data processing system, comprising:

• at least first and second coherency domains each containing at least one processing unit;
• an interconnect fabric coupling said first and second coherency domains;
• a memory coupled to said interconnect fabric, said memory including an address translation table having a translation table entry utilized to translate virtual memory addresses to real memory addresses, wherein said translation table entry includes scope information for broadcast operations targeting addresses within a memory region associated with said translation table entry;
• and
• scope prediction logic within the first coherency domain that predictively selects a scope of broadcast of an operation on an interconnect fabric of the data processing system by reference to said scope information within said address translation table entry.

A processing unit for a data processing system including at least first and second coherency domains coupled by an interconnect fabric, said processing unit comprising:

• a processor;
• a memory coupled to said processor, said memory including an address translation table entry utilized to translate virtual memory addresses to real memory addresses, wherein said address translation table entry includes scope information for broadcast operations targeting addresses within a memory region associated with said translation table entry;
• and
• scope prediction logic that predictively selects a scope of broadcast of an operation to be issued by said processing unit on the interconnect fabric of the data processing system by reference to said scope information within said address translation table entry.
