ARM Architecture - Exception and Interrupt Model

Which of the following is the correct syntax to define an exception handler in ARM assembly?

Adef handler(): pass

Bexception_handler() { }

Cinterrupt -> handle_event

Dhandler: B exception_routine

Step-by-Step Solution

Solution:

Step 1: Recognize ARM assembly syntax
ARM assembly uses labels and branch instructions like 'B' to jump to routines.
Step 2: Identify the correct label and branch format
handler: B exception_routine shows a label 'handler:' and a branch 'B exception_routine', which is valid ARM syntax.
Final Answer:
handler: B exception_routine -> Option D
Quick Check:
ARM exception handler syntax = label + branch [OK]

Quick Trick: ARM assembly uses labels and B for branches [OK]
