ARM Architecture - Subroutines and Stack
What advantage do subroutines provide when structuring ARM assembly programs?
AThey allow separation of code into manageable sections
BThey automatically optimize the code for speed
CThey eliminate the need for comments
DThey prevent the use of global variables
Step-by-Step Solution
Solution:

  1. Step 1: Identify modularity concept

    Modularity means dividing code into parts.

  2. Step 2: Role of subroutines

    Subroutines separate functionality into distinct blocks.

  3. Final Answer:

    They allow separation of code into manageable sections -> Option A

  4. Quick Check:

    Modularity improves code clarity [OK]
Quick Trick: Subroutines separate code into clear sections [OK]
Common Mistakes:
  • Believing subroutines optimize speed automatically
  • Thinking subroutines replace comments
