NIMCET 2009 Computer PYQ — On receiving an interrupt from an I/O device, the CPUs… | Mathem Solvex

A.
hand over the control of address and data bus to interrupting device.
B.
branch off to interrupt service subroutine immediately.
C.
branch off to interrupt service subroutine after completion of current instruction.
(Correct Answer)
D.
None of the above

Correct Answer:

branch off to interrupt service subroutine after completion of current instruction.

Explanation

When an $I/O$ device sends an interrupt signal to the $CPU$ , the following sequence typically occurs:

Instruction Completion: The $CPU$ does not stop what it is doing mid-way through an operation. It finishes executing the current instruction first to maintain the integrity of the program state.
Saving State: Before branching, the $CPU$ saves the current state (like the Program Counter and registers) onto the stack so it can return to exactly where it left off.
Branching: Only after the current instruction cycle is complete does the $CPU$ branch to the Interrupt Service Routine (ISR) or subroutine.
