Abstract

A computing system is provided with real-time capabilities so that the system is capable of running applications such that one or more real-time criteria are satisfied. An interrupt architecture of the computing system is disabled. The interrupt architecture generates interrupts sent to a firmware of the computing system in response to events. A different architecture is substituted within the computing system for the interrupt architecture. The different architecture is responsive to the events without violating the real-time criteria. In response to the events occurring, the different architecture causes one or more corrective actions to be performed.
