摘要： In one embodiment, a switch is configured to be coupled to an interconnect. The switch comprises a plurality of storage locations and an arbiter control circuit coupled to the plurality of storage locations. The plurality of storage locations are configured to store a plurality of requests transmitted by a plurality of agents. The arbiter control circuit is configured to arbitrate among the plurality of requests stored in the plurality of storage locations. A selected request is the winner of the arbitration, and the switch is configured to transmit the selected request from one of the plurality of storage locations onto the interconnect. In another embodiment, a system comprises a plurality of agents, an interconnect, and the switch coupled to the plurality of agents and the interconnect. In another embodiment, a method is contemplated.

摘要： In various embodiments, an apparatus comprises a plurality of agents and an interconnect. In one embodiment, the plurality of agents includes first through fourth agents. The interconnect comprises a plurality of segments that are switchable (e.g. using a plurality of selection circuits) to form communication paths between the agents, and a first segment is included in a first communication path from the first agent to the second agent, and is also included in a second communication path from the third agent to the fourth agent. In another embodiment, each segment is driven by a selection circuit. At least one selection circuit has at least one segment and an output from at least one agent as inputs. In yet another embodiment, an arbiter is configured to determine a communication path on the interconnect for each requesting agent to the destination agent over the segments. The arbiter is configured to arbitrate among a subset of requests for which each segment in the corresponding communication path is available.

摘要： In one embodiment, a cache comprises a data memory comprising a plurality of data entries, each data entry having capacity to store a cache block of data, and a cache control unit coupled to the data memory. The cache control unit is configured to dynamically allocate a given data entry in the data memory to store a cache block being cached or to store data that is not being cache but is being staged for retransmission on an interface to which the cache is coupled.
