  • Publication number: 20060041706
    Abstract: A computer system has a central processing unit, a north bridge electrically connected to the central processing unit, memory electrically connected to the north bridge, a south bridge electrically connected to the north bridge, and a peripheral device electrically connected to the south bridge. The south bridge includes a register for storings a plurality of pre-fetched read data to provide the pre-fetched read data to the peripheral device. The north bridge has an address queue module for storing an address of the pre-fetched read data, and a snooping module for checking whether a data value corresponding to the address is updated by the CPU. The north bridge assists the south bridge in obtaining and maintaining the pre-fetched read data for high efficiency and accuracy of read caching of the south bridge.

  • Publication number: 20050172055
    Abstract: A method for facilitating read completion in a computer system supporting write posting operations. A posted memory write and its associated tag both need to be buffered, where the associated tag is designated to a master of a local bus originating the posted memory write. When a read request moving in an opposite direction of the posted memory write is detected, the read request is checked to identify which master of the local bus is addressed. A destination tag is then assigned to the read request contingent upon the currently addressed master. Further, the destination tag of the read request is compared with the associated tag of the posted memory write. If the destination tag of the read request differs from the associated tag of the posted memory write, the read request can be completed directly regardless of the outstanding posted writes.
