Question 1.
What does the fetch step involve?
Show hintHide hint
Think about how the CPU knows which instruction to execute next.
Question 2.
Define interrupt in CPU operations.
Show hintHide hint
This is something that helps the CPU manage tasks efficiently.
3Question 3.
What does the fetch step in the FDE cycle involve?
- Executing the current instruction
- Retrieving the next instruction from memory
- Decoding the instruction
Show hintHide hint
Think about where the CPU looks for instructions.
4Question 4.
True or False: An immediate addressing mode allows the CPU to fetch operands from the instruction itself.
- True
- False
Show hintHide hint
Remember how immediate addressing provides speed in data access.
Question 5.
Create a sequence of operations in a CPU that involves using both direct and indirect addressing modes. Explain how the CPU handles each.
Show hintHide hint
Break down the steps for each instruction and how memory addresses are involved.
Question 6.
Discuss how the presence of interrupts might affect real-time processing applications in a CPU environment.
Show hintHide hint
Consider situations where multiple tasks need attention simultaneously.
