ARM Architecture - Control Flow Instructions
What is the main purpose of a loop in ARM assembly language?
ATo store data in memory
BTo jump to a different program section once
CTo perform arithmetic operations
DTo repeat a set of instructions multiple times
Step-by-Step Solution
Solution:

  1. Step 1: Understand the concept of loops

    Loops are used to repeat instructions multiple times to avoid writing the same code repeatedly.

  2. Step 2: Identify the purpose in ARM assembly

    In ARM assembly, loops use registers and branch instructions to repeat code sections.

  3. Final Answer:

    To repeat a set of instructions multiple times -> Option D

  4. Quick Check:

    Loops repeat instructions [OK]
Quick Trick: Loops repeat code blocks until a condition ends [OK]
Common Mistakes:
  • Confusing loops with data storage
  • Thinking loops perform only arithmetic
  • Assuming loops run only once
