ABSTRACT:
An Interrupt Manager for servicing interrupts. An interrupt is performed only after an atomic operation (Operating System instruction) is completed. After completion of each operating system instruction, a first command immediately allows any interrupt to be serviced. A second command then immediately closes out any interrupts, allowing for the execution of the next operating system instruction.
