Question 1.
What is the purpose of an interrupt?
Show hintHide hint
Think about what happens when an external device needs attention.
Question 2.
What does the Program Counter (PC) do?
Show hintHide hint
Consider the role of the PC in tracking instruction flow.
3Question 3.
What occurs when an interrupt is received during instruction execution?
- The current instruction continues executing
- The CPU stops and services the interrupt
- The program terminates
Show hintHide hint
Think about how urgent tasks are handled.
4Question 4.
The Instruction Cycle Code (ICC) value for execution is?
- 00
- 01
- 10
- 11
Show hintHide hint
Remember the definitions of each ICC value.
Question 5.
You have a multi-core processor that handles multiple interrupts. Design a method to prevent race conditions that could occur during interrupt handling.
Show hintHide hint
Consider how systems manage different priority tasks.
Question 6.
A system frequently encounters interrupts during a critical instruction execution. Assess the impact of this on program performance and potential strategies to mitigate it.
