ABSTRACT:
This disclosure describes the acceleration of system interrupts between one operating system and another operating system which run in a guest-host relationship. The execution time required by the host operating system (HOS) to service system interrupts is substantially reduced, thus allowing the guest operating system (GOS) to execute more efficiently. The invention is implemented by enhancing HOS supervisor services and HOS dispatching functions so that GOS resident supervisor functions are bypassed.
