Question 1.
What is immediate addressing?
Show hintHide hint
Think about instructions containing the operands directly.
Question 2.
What does direct addressing mean?
Show hintHide hint
Recall how direct memory access works.
3Question 3.
What does displacement addressing combine?
- Only fixed addresses
- Only variable offsets
- Fixed addresses with variable offsets
Show hintHide hint
It's about flexibility in memory management.
4Question 4.
True or False: Indirect addressing only requires a single memory access.
- True
- False
Show hintHide hint
Consider how data is retrieved.
Question 5.
Design an algorithm using displacement addressing to manipulate array data effectively. Explain how displacement aids in this process.
Show hintHide hint
Consider how each element can be accessed using a base pointer and an incrementing offset.
Question 6.
Evaluate a given snippet of assembly code that uses various addressing modes. Determine which mode optimally accesses data and explain why.
