ABSTRACT:
Priority interrupt hardware monitors for the existence of, and determines the relative importance of requests to determine or attempt to determine when to interrupt an executing process on a processor. The processor may be interrupted only when the hardware determines that something more important needs to be done than what is being done by the currently executing process. Additionally, the processor may set interrupts for itself so that a portion of an executing process may be executed at a higher priority than that required for the remaining portion of the same process.
