Question

What is Interrupt? Draw the Interrupt Vector Table (IVT) for the Interrupt occurred in the following ASM code.

CSM:                                                                                 ISR for INT 19 H:

0000: 3000 :- MOV AX, 0200 H                                            0F010:- L1: DEC AX            

0000: 3002 :- MOV BX, 0000 H                                            0F011:- JNZ AX, L1

0000: 3004 :- INC BX                                                          0F012:- IRET

0000: 3005 :- INT 19 H

0000: 3006 :- MOV DX, BX                      

Answer 1

An interrupt is a condition that halts the microprocessor temporarily to work on a different task and then return to its previous task. An interrupt is an event or signal that request to the attention of CPU And An "interrupt vector table" (IVT) is a data structure that associates a list of interrupt handlers with a list of interrupt requests in a table of interrupt vectors. Each entry of the interrupt vector table called an interrupt vector.
