Question 1.
What does an interrupt indicate?
Show hintHide hint
Think about events external to the CPU that may need immediate processing.
Question 2.
What is the purpose of the Program Counter?
Show hintHide hint
Consider what helps the CPU know where to continue executing after an instruction.
3Question 3.
What does the Program Counter (PC) do?
- Stores the current instruction controls execution flow.
- Tracks the address of the next instruction to execute.
- Controls input/output devices.
Show hintHide hint
Recall which component directs the flow of instruction execution.
4Question 4.
True or False: The Instruction Cycle Code (ICC) helps determine if the CPU is executing the instruction, fetching it, or servicing an interrupt.
- True
- False
Show hintHide hint
Consider what keeps the CPU organized during instruction processing.
Question 5.
Design a flowchart that depicts the fetch phase, including the handling of interrupts and the role of the program counter.
Show hintHide hint
Remember to represent decision points clearly to show interrupt checks.
Question 6.
Discuss the implications of not saving the PC value during an interrupt. What potential issues could arise?
Show hintHide hint
Think about how processes rely on correct sequential order for execution.
