Question 1.
What does the Program Counter (PC) do during an interrupt?
Show hintHide hint
Think about what happens to the instruction being executed.
Question 2.
Name the three phases of the instruction cycle.
Show hintHide hint
They're often referred to as stages within the instruction cycle.
3Question 3.
What happens when an interrupt occurs during instruction execution?
- The CPU ignores the interrupt.
- The CPU saves the state and services the interrupt.
- The CPU completes the current instruction without interruption.
Show hintHide hint
Think about how urgent tasks are managed in computing.
4Question 4.
True or False: The Instruction Cycle Code (ICC) changes based on the current phase of instruction execution.
- True
- False
Show hintHide hint
Recall how phases of instruction execution are managed.
Question 5.
Imagine you're designing a CPU that can handle multiple interrupts. How would you modify the current approach to save the state during the interrupt service?
Show hintHide hint
Consider how each interrupt might be of varying importance and require its handling.
Question 6.
How would the CPU behave if it encountered a high-priority interrupt while executing a critical instruction? Describe the steps it would take.
Show hintHide hint
Focus on how critical tasks might take precedence in processing order.
