Common Functions of Interrupts?

v  Interrupt transfers control to the interrupt service routine generally, through the interrupt vector, which contains the addresses of all the service routines.

v  Interrupt architecture must save the address of the interrupted instruction.

v  Incoming interrupts are disabled while another interrupt is being processed to prevent a lost interrupt.

v  A trap is a software-generated interrupt caused either by an error or a user request.

v  An operating system is interrupt driven.
