    摘要: A method is described that involves controlling the traffic levels through an uncore to provide thermal management for the uncore. The method including determining if an uncore's temperature in a first uncore state is above a first threshold value and changing the first uncore state to a second uncore state if the uncore temperature is above the first threshold value.

    摘要: A method and a processor may include storing a first set of data in a data array in a cache unit substantially concurrently to reading a second set of data from the data array, and using the second set of data to generate error correction data corresponding to the first set of data. A method or processor may include reading an entry from a cache in a processor and executing two or more error detection mechanisms on the entry substantially concurrently.

    摘要: A method and apparatus for a loop predictor for predicting the end of a loop is disclosed. In one embodiment, the loop predictor may have a predict counter to hold a predict count representing the expected number of times that a predictor stew value will repeat during the execution of a given loop. The loop predictor may also have one or more running counters to hold a count of the times that the stew value has repeated during the execution of the present loop. When the counter values match the predictor may issue a prediction that the loop will end.

    摘要: A request hint is issued prior to or while identifying whether requested data and/or one or more instructions are in a first memory. A second memory is accessed to fetch data and/or one or more instructions in response to the request hint. The data and/or instruction(s) accessed from the second memory are stored in a buffer. If the requested data and/or instruction(s) are not in the first memory, the data and/or instruction(s) are returned from the buffer.

    摘要: The present invention discloses a method and apparatus for synchronizing weakly ordered write combining operations. A memory controller has a buffer to service memory accesses. A store fence instruction is dispatched to the memory controller. If the buffer contains at least a data written by at least one of the weakly ordered write combining operations prior to the store fence instruction, then the store fence instruction is blocked until a block in the buffer containing the data is globally observed. If the buffer does not contain any data written by at least one of the write combining operations prior to the store fence instruction, then the store fence instruction is accepted by the memory controller.
