Question 1.
What is the primary function of the Instruction Register?
Show hintHide hint
Think about what an instruction register stores during CPU operation.
Question 2.
How many stages are typically required for memory indirect addressing?
Show hintHide hint
Consider how many memory accesses take place.
3Question 3.
In indirect addressing, how is the operand accessed?
- Directly through its memory address
- Using another address
- By using a constant value
Show hintHide hint
Think about how an address reference is made.
4Question 4.
True or False: Memory Indirect Addressing typically requires more stages than Register Indirect Addressing.
- True
- False
Show hintHide hint
Consider how many accesses are needed for each type.
Question 5.
Design a sequence to execute an indirect load instruction from memory to a register. Explain each step including addressing mode.
Show hintHide hint
Trace through the steps carefully to ensure all stages are accounted for.
Question 6.
Analyze the performance impact of choosing indirect addressing over direct addressing in a loop iteration scenario.
Show hintHide hint
Quantify the time taken for multiple loop executions to illustrate your point.
