    摘要: A method and apparatus for delivering APIC interrupts to a processor, and between processors, as FSB transactions. Interrupts and hardware signals, generated by a PCI device, are converted into an upstream memory write interrupt and further converted into an FSB interrupt transaction, received by a processor. Interrupts marked as lowest priority re-directable are redirected based on task priority information. Support for XTPR transactions to update XTPR registers is provided. Preferred ordering of XTPR update transactions and interrupts to be redirected is provided.

    摘要: A system is described for servicing a full cache line in response to a partial cache line request. The system includes a storage to store at least one cache line, a hit/miss detector, and a data mover. The hit/miss detector receives a partial cache line read request from a requesting agent and dispatches a fetch request to a memory device to fetch a full cache line data that contains data requested in the partial cache line read request from the requesting agent. The data mover loads the storage with the full cache line data returned from the memory device and forwards a portion of the full cache line data requested by the requesting agent. If data specified in a subsequent partial cache line request from the requesting agent is contained within the full cache line data specified in the previously dispatched fetch request, the hit/miss detector will send a command to the data mover to forward another portion of the full cache line data stored in the storage to the requesting agent. In one embodiment, the system also includes a write combining logic to combine two or more consecutive write requests that meet defined conditions into a single write request.

    摘要: A prioritized address decoder has been disclosed. One embodiment of the prioritized address decoder includes a first comparator to compare a destination device address of data with a first address range associated with a first device and a second comparator coupled to the first comparator to compare the destination device address with a second address range associated with a second device, wherein the data is sent to the second device in response to a first output of the first comparator and a second output of the second comparator.
