Abstract
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.
