    Abstract: 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.

    Abstract: A technique to monitor events within a computer system or integrated circuit. In one embodiment, a software-accessible event monitoring storage and hardware-specific monitoring logic are selectable and their corresponding outputs may be monitored by accessing a counter to count events corresponding to each of software-accessible storage and hardware-specific monitoring logic.

    Abstract: A front side bus swizzle mechanism modifies the front side (address and data) bus on a chip so that, when the chip is positioned on one side of a printed circuit board, connection to a second chip located on the opposite side of the printed circuit board is simplified. The simplified connection may result in less complexity and minimize the consumption of additional printed circuit board real estate.
