    摘要: A memory control apparatus includes a data stream format converter and a physical layer converter. The data stream format converter is configured to convert an incoming data stream that has a data stream format corresponding to a first memory type into a format-converted data stream that has a data stream format corresponding to a second memory type. The second memory type is different from the first memory type. The physical layer converter is configured to convert the format-converted data stream into a physical-layer-converted data stream that has at least one physical parameter corresponding to the second memory type. The format-converted data stream has at least one physical parameter corresponding to the first memory type.

    摘要: A data processing system includes at least a first through third processing nodes coupled by an interconnect fabric. The first processing node includes a master, a plurality of snoopers capable of participating in interconnect operations, and a node interface that receives a request of the master and transmits the request of the master to the second processing unit with a nodal scope of transmission limited to the second processing node. The second processing node includes a node interface having a directory. The node interface of the second processing node permits the request to proceed with the nodal scope of transmission if the directory does not indicate that a target memory block of the request is cached other than in the second processing node and prevents the request from succeeding if the directory indicates that the target memory block of the request is cached other than in the second processing node.

    摘要: In a first aspect, a method for maintaining control structure coherency is provided. The method includes the steps of (1) writing a pointer to a control structure in a hardware update list while one or more portions of the control structure are accessed by hardware during a hardware update operation; and (2) delaying a software access to one or more portions of the control structure during a software update operation while the pointer to the control structure is on the hardware update list. Numerous other aspects are provided.

    摘要: In a first aspect, a first method is provided for adjusting memory system calibration. The first method includes the steps of (1) while in a first operating state, calibrating the memory system using a first amount of calibration data so that functional data may be read from and written to memory of the memory system; and (2) while in a second operating state, calibrating the memory system using a second amount of calibration data so that functional data may be read from and written to the memory, wherein the second amount of calibration data is smaller than the first amount of calibration data. Numerous other aspects are provided.
