    摘要: A system comprises a first node operative to provide a source broadcast requesting data. The first node associates an F-state with a copy of the data in response to receiving the copy of the data from memory and receiving non-data responses from other nodes in the system. The non-data responses include an indication that at least a second node includes a shared copy of the data. The F-state enabling the first node to serve as an ordering point in the system capable of responding to requests from other nodes in the system with a shared copy of the data.

    摘要: A system may comprise a first node that includes an ordering point for data, the first node being operative to employ a write-back transaction associated with writing the data back to memory. The first node broadcasts a write-back message to at least one other node in the system in response to an acknowledgement provided by the memory indicating that the ordering point for the data has migrated from the first node to the memory.

    摘要: Systems and methods are disclosed for interaction between different cache coherency protocols. One system may comprise a home node that receives a request for data from a first node in a first cache coherency protocol. A second node provides a conflict response to a request for the data from the home node. The conflict response indicates that an ordering point for the data is migrating according to a second cache coherency protocol, which is different from the first cache coherency protocol.

    摘要: Multi-processor systems and methods are disclosed. One embodiment may comprise a multi-processor system comprising at least one data fill provided to a source processor in response to a source request by the source processor, and a coherent signal generated by the multi-processor system that provides an indication of which data fill of the at least one data fill is a coherent data fill.

    摘要: Systems and method are disclosed for providing responses for different cache coherency protocols. One embodiment may comprise a system that includes a first node employing a first cache coherency protocol. A detector associated with the first node detects a condition based on responses provided by the first node to requests provided according to a second cache coherency protocol, the second cache coherency protocol being different from the first cache coherency protocol. The first node provides a response to a given one of the requests to the first node that varies based on the condition detected by the detector.

    摘要: A system comprises a first node including data having an associated state. The associated state of the data at the first node is a modified state. The system also comprises a second node operative to provide a non-migratory source broadcast request for the data. The first node is operative in response to the non-migratory source broadcast request to provide the data to the second node and to transition the associated state of the data at the first node from the modified state to an owner state without updating memory. The second node is operative to receive the data from the first node and assign a shared state to an associated state of the data at the second node.

    摘要: A system comprises a first node that provides a broadcast request for data. The first node receives a read conflict response to the broadcast request from the first node. The read conflict response indicates that a second node has a pending broadcast read request for the data. A third node provides the requested data to the first node in response to the broadcast request from the first node. The first node fills the data provided by the third node in a cache associated with the first node.
