    摘要: A system includes a processor coupled to a memory through a memory controller. The memory controller includes first and second queues. The memory controller receives memory requests from the processor, assigns a priority to each request, stores each request in the first queue, and schedules processing of the requests based on their priorities. The memory controller changes the priority of a request in the first queue in response to a trigger, sends a next scheduled request from the first queue to the second queue in response to detecting the next scheduled request has the highest priority of any request in the first queue, and sends requests from the second queue to the memory. The memory controller changes the priority of different types of requests in response to different types of triggers. The memory controller maintains a copy of each request sent to the second queue in the first queue.

    摘要: In one embodiment, a node comprises a plurality of processor cores and a node controller coupled to the processor cores. The node controller is configured to route communications from the processor cores to other devices in a computer system. The node controller comprises a circuit coupled to receive the communications from the processor cores. In a redundant execution mode in which at least a first processor core is redundantly executing code that a second processor core is also executing, the circuit is configured to compare communications from the first processor core to communications from the second processor core to verify correct execution of the code. In some embodiments, the processor cores and the node controller may be integrated onto a single integrated circuit chip as a CMP. A similar method is also contemplated.

    摘要: In one embodiment, a processing node includes a plurality of processor cores and a reconfigurable interconnect. The processing node also includes a controller configured to schedule transactions received from each processor core. The interconnect may be coupled to convey between a first processor core and the controller, transactions that each include a first corresponding indicator that indicates the source of the transaction. The interconnect may also be coupled to convey transactions between a second processor core and the controller, transactions that each include a second corresponding indicator that indicates the source of the transaction. When operating in a first mode, the interconnect is configurable to cause the first indicator to indicate that the corresponding transactions were conveyed from the second processor core and to cause the second indicator to indicate that the corresponding transactions were conveyed from the first processor core.
