Question 1.
What is the basic function of indirect addressing mode?
Show hintHide hint
Think about how registers are used to determine memory locations.
Question 2.
If R1 contains 3, what is the effective address when you add it to 2?
Show hintHide hint
Simply add the values together.
3Question 3.
What does indirect addressing use to calculate effective addresses?
- Direct values
- Registers
- Memory locations
Show hintHide hint
Recall how registers provide dynamic addressing.
4Question 4.
True or False: Indirect addressing can only be used with immediate values.
- True
- False
Show hintHide hint
Think about the scope and functionality of indirect addressing.
Question 5.
Suppose you have a system that starts with R1 = 2 and R5 = 0. If accessing an array located at memory indices 2 to 5, describe how the values in R5 will change after each access.
Show hintHide hint
Consider how each increment of R1 allows access to a new memory value.
Question 6.
Analyze the relationship between opcode size and how many memory accesses occur for a complex indirect addressing operation in a multi-word instruction setup.
Show hintHide hint
Reflect on the breakdown of instruction components and their respective memory locations.
