Data processing system and method for predictively selecting a scope of broadcast of an operation |
摘要 |
A cache coherent data processing system includes at least first and second coherency domains coupled for communication. The first and second coherency domains each include a respective one of first and second cache memories. A master in the first coherency domain selects a scope of an initial broadcast of an operation from among a first scope including only the first coherency domain and a second scope including both the first and second coherency domains based, at least in part, upon a type of the operation. The master then performs an initial broadcast of the operation within the cache coherent data processing system utilizing the selected scope. |
