摘要： Systems, methods, and other embodiments associated with reducing interrupt latency are described. According to one embodiment, an apparatus includes a buffer storing instructions awaiting execution by an execution device. The apparatus also includes an interrupt logic that, in response to receiving an interrupt, classifies instructions as either safe or unsafe. An unsafe instruction will cause the instructions to execute in a manner inconsistent with an instruction set architecture. The interrupt logic also establishes an interrupt boundary between safe and unsafe instructions, and causes the interrupt to be processed at the interrupt boundary such that the interrupt is processed before processing of the unsafe instructions.

摘要： A system and method of tracking multiple non-identification tagged requests in a system with multiple responders using one or more tracking queues. In some embodiments, the system and method may be implemented in a snoop filter covering multiple caches. In some embodiments, a data-less bus query may be used to update the status of a requested line.

摘要： Systems, methods, and other embodiments associated with selective shorting are described. According to one embodiment, an apparatus includes a selective shorting device connected between clock branches. The selective shorting device is configured to selectively electrically connect the clock branches to one another and to selectively electrically disconnect the clock branches from one another. The apparatus also includes a selective shorting control mechanism that controls the selective shorting device to electrically connect the clock branches during a controlling portion of a clock signal. The selective shorting control mechanism is configured to electrically disconnect the clock branches in the absence of the controlling portion.
