    摘要: A method of interfacing two components of a computing system is provided wherein the method includes providing a pair of unidirectional, point-to-point buses to transmit data between a master bus controller of the computing system and a slave bus controller of a processor unit of the computing system. The method also includes providing means for transmitting a command packet with an address associated with data pertaining to the command from the master bus controller to the slave bus controller. In addition, the method includes providing means for determining by the slave bus controller whether the slave bus controller can accept the command. The method further includes providing means for transmitting an acknowledgement from the slave bus controller to the master bus controller after the slave bus controller receives a first signaling interval for the command packet if the slave bus controller can accept the command packet.

    摘要: A method, system and computer program product for handling write requests in a data processing system is disclosed. The method comprises receiving on an interconnect bus a first write request targeted to a first address and receiving on the interconnect bus a subsequent second write request targeted to a subsequent second address. The subsequent second write request is completed prior to completing the first write request, and, responsive to receiving a read request targeting the second address before the first write request has completed, data associated with the second address of the second write request is supplied only after the first write request completes.

    摘要: A cache coherent data processing system includes a plurality of processing units each having at least an associated cache, a system memory, and a memory controller that is coupled to and controls access to the system memory. The system memory includes a plurality of storage locations for storing a memory block of data, where each of the plurality of storage locations is sized to store a sub-block of data. The system memory further includes metadata storage for storing metadata, such as a domain indicator, describing the memory block. In response to a failure of a storage location for a particular sub-block among the plurality of sub-blocks, the memory controller overwrites at least a portion of the metadata in the metadata storage with the particular sub-block of data.

    摘要: A system and method of recovering from errors in a data processing system. The data processing system includes one or more processor cores coupled to one or more memory controllers. The one or more memory controllers include at least a first memory interface coupled to a first memory and at least a second memory interface coupled to a second memory. In response to determining an error has been detected in the first memory, access to the first memory via the first memory interface is inhibited. Also, the first memory interface is locally restarted without restarting the second memory interface.

    摘要: A novel roof vent in accordance with the present invention, utilizes a vent pipe communicating with a shroud, where the shroud compatibly fits over a ridge vent on a roof. The vent pipe is extended above the roof, sufficiently so as to rise above the anticipated level of snow load that may be experienced in the locale of the application. The roof vent of the preferred embodiment includes an apron that adjustably fits the roof pitch of the installation and further includes a ridge vent cutout for compatibly fitting over the ridge vent. In one version of the present invention, cosmetic dress may be used to allow the roof vent to blend with architectural requirements without impacting the functionality of the roof vent operation.

    摘要: Methods, data processing systems, and program products are disclosed that support the definition and accessing of links indicating a relationship between configuration construct instances, such as Dial and Dial group instances, within a digital design. According to one method, first and second latches within the digital design are specified in at least one HDL statement within one or more HDL files representing the digital design. In the one or more HDL files, a first configuration construct instance referencing the first latch and a second configuration construct instance referencing the second latch are also defined. The first and second configuration construct instances provide interfaces through which values of the first and second latches can be accessed. In addition, a link indicating a relationship between the first and second configuration construct instances is also defined within the one or more HDL files.
