start in ARM assembly?Which of the following represents the correct way to write an unconditional branch to label start in ARM assembly?
easy📝 Factual Q3 of 15
Step-by-Step Solution
Solution:
Step 1: Recall ARM branch syntax
The unconditional branch instruction in ARM isBfollowed by the label.Step 2: Analyze options
BRandJMPare not ARM instructions;BLis branch with link (used for function calls).Final Answer:
B start is the correct syntax for an unconditional branch.Quick Check:
Unconditional branch uses B [OK]
Quick Trick: Use B label for unconditional branch [OK]
Common Mistakes:
- Using JMP instead of B in ARM
- Confusing BL with B
- Using BR which is not an ARM instruction
