What is the main reason ARM exceptions save the processor state during a hardware event?

easy📝 Conceptual Q2 of 15
ARM Architecture - Exception and Interrupt Model
What is the main reason ARM exceptions save the processor state during a hardware event?
ATo slow down the processor for safety
BTo erase all data and start fresh after the event
CTo allow the processor to resume normal work after handling the event
DTo permanently disable the hardware causing the event
Step-by-Step Solution
Solution:

  1. Step 1: Identify the purpose of saving state

    Saving state means remembering where the processor was before the event.

  2. Step 2: Understand resuming normal work

    This saved state lets the processor continue exactly where it left off after handling the event.

  3. Final Answer:

    To allow the processor to resume normal work after handling the event -> Option C

  4. Quick Check:

    Saving state = resume work after event [OK]
Quick Trick: Save state to continue after event handling [OK]
Common Mistakes:
  • Thinking state is erased after event
  • Believing processor slows down intentionally
  • Assuming hardware is disabled permanently
