Show hintHide hint
Think about how addresses are specified in each mode.
Question 2.
What does the MAR stand for?
Show hintHide hint
Consider what role it plays in retrieving data.
3Question 3.
What does indirect addressing require before fetching the operand?
- Directly gets the operand
- Fetches the address first
- Uses immediate values

4Question 4.
True or False: Register indirect addressing can help improve execution speed.
- True
- False
Show hintHide hint
Consider how registers compare with memory access times.
Question 5.
You have an instruction that requires an indirect address to fetch an operand stored in memory. Detail the steps the CPU must follow to successfully load this operand.
Show hintHide hint
Think through each stage of the processing pipeline.
Question 6.
Imagine you're designing a new CPU. How would you optimize the register indirect mode to improve performance? Discuss potential changes.
Show hintHide hint
Consider how CPU architectures balance speed and resource efficiency as you think through your design.
