Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What is an interrupt?

💡 Hint: Think about what happens when a device needs attention from the CPU.

Question 2

Easy

What do we mean by context saving?

💡 Hint: How does the CPU remember what it was doing before the interrupt?

Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What happens first when an interrupt is received?

  • The interrupt service routine is executed
  • The current instruction is completed
  • The context is restored

💡 Hint: Think about the order of operations when a request interrupts processing.

Question 2

True or False: Flag bits can be set by the programmer.

  • True
  • False

💡 Hint: Recall which flags can be modified by the programmer during execution.

Challenge Problems

Push your limits with challenges.

Question 1

Design a mini project that simulates an environment where multiple devices send interrupts to the CPU, illustrating how the system handles context saving and restoring.

💡 Hint: Use a programming language to implement this simulation and visualize interrupt handling.

Question 2

Evaluate how different programmer strategies can influence the effective management of interrupts in real-time systems.

💡 Hint: Consider real-time application needs and their critical coding practices for interrupts.
