    摘要: In one embodiment, a processor comprises a scheduler configured to issue a first instruction operation to be executed and an execution core coupled to the scheduler. Configured to execute the first instruction operation, the execution core comprises a plurality of replay sources configured to cause a replay of the first instruction operation responsive to detecting at least one of a plurality of replay cases. The scheduler is configured to inhibit issuance of the first instruction operation subsequent to the replay for a subset of the plurality of replay cases. The scheduler is coupled to receive an acknowledgement indication corresponding to each of the plurality of replay cases in the subset, and is configured to inhibit issuance of the first instruction operation until the acknowledgement indication is asserted that corresponds to an identified replay case of the subset.

    摘要: In one embodiment, a processor comprises a buffer and a control unit coupled to the buffer. The buffer is configured to store requests to be transmitted on an interconnect on which the processor is configured to communicate. The buffer is coupled to receive a first uncacheable load request having a first address. The control unit is configured to merge the first uncacheable load request with a second uncacheable load request that is stored in the buffer responsive to a second address of the second load request matching the first address within a granularity. A single transaction on the interconnect is used for both the first and second uncacheable load requests, if merged. Separate transactions on the interconnect are used for each of the first and second uncacheable load requests if not merged.

    摘要: In one embodiment, an interface unit comprises an address buffer and a control unit coupled to the address buffer. The address buffer is configured to store addresses of processor core requests generated by a processor core and addresses of snoop requests received from an interconnect. The control unit is configured to maintain a plurality of queues, wherein at least a first queue of the plurality of queues is dedicated to snoop requests and at least a second queue of the plurality of queues is dedicated to processor core requests. Responsive to a first snoop request received by the interface unit from the interconnect, the control unit is configured to allocate a first address buffer entry of the address buffer to store the first snoop request and to store a first pointer to the first address buffer entry in the first queue. Responsive to a first processor core request received by the interface unit from the processor core, the control unit is configured to allocate a second address buffer entry of the address buffer to store the first processor core request and to store a second pointer to the second address buffer entry in the second queue.
