4 cards from this section. Quick, good the night before a test.
What is the effective address if the base address is 1000 and the displacement is 50?
Add the base address and the displacement.
What role does an index register play in index displacement?
Think about how we access data in arrays.
What does displacement addressing mode help calculate?
Think about what needs to happen to get to a specific memory location.
In index displacement mode, we add the index value to the base address. True or False?
Recall how we access elements in an array.
Create a pseudo-code to demonstrate how index displacement can be used to retrieve the third element from an array.
Keep the index in mind as you access elements in an array.
Discuss the pros and cons of using displacement addressing modes in complex systems.
Consider both the efficiency and the complexity.
