    摘要: Embodiments of methods and apparatuses for multicast handling in mixed core systems have been described. A method for multicast handling in mixed core systems includes configuring broadcast group registers located in targets. The method also includes receiving a request to create a broadcast group and creating the broadcast group. Finally, the method includes transmitting the broadcast group to targets with broadcast group registers that correspond to the broadcast group.

    摘要: An algorithm for selecting a directory entry in a multiprocessor-node system. In response to a memory request from a processor in a processor node, the algorithm finds an available entry to store information about the requested memory line. If at least one entry is available, then the algorithm uses one of the available entries. Otherwise, the algorithm searches for a “shared” entry. If at least one shared entry is available, then the algorithm uses one of the shared entries. Otherwise, the algorithm searches for a “dirty” entry. If at least one dirty entry is available, then the algorithm uses one of the dirty entries. In selecting a directory entry, the algorithm uses a “least-recently-used” (LRU) algorithm because an entry that was not recently used is more likely to be stale. Further, to improve system performance, the algorithm preferably uses a shared entry before using a dirty entry. In the preferred embodiment, the processor node that utilizes the invention includes at least one processor having a respective cache connected via a bus to main memory.

    摘要: Embodiments of apparatuses, systems, and methods are described for a machine-readable medium having instructions stored thereon, which, when executed by a machine, to cause the machine to generate a representation of an apparatus. The apparatus includes a bridge agent, a first interconnect, and a second interconnect. The bridge agent is configured by bridge control signals to control transmission of a communication between the first interconnect and the second interconnect. The representation may be a sequence of instructions written in a programming language to mimic in a computer simulation environment attributes derived from a projected fabricated hardware instance of the apparatus.

    摘要: In general, methods and apparatus for implementing a Quality of Service (QoS) model are disclosed. A Quality of Service (QoS) contract with an initiating network device may be satisfied. A request may be received from the initiating network device in a first time less than or equal to an ordinal number times an arrival interval. The ordinal number signifies a position of the request among a group of requests. The request that has been serviced may be returned to the initiator in a second time less than or equal to a constant term plus the ordinal number times a service interval.
