Question 1

What is the primary purpose of an Interrupt Service Routine?

  • To continue executing current instructions
  • To handle an interrupt
  • To define a new task

💡 Hint: Consider what the CPU does when it receives a signal it cannot ignore.

Question 2

True or False: The Program Counter must be incremented after every instruction before checking for interrupts.

  • True
  • False

💡 Hint: Think about the order of operations during instruction processing.

Challenge Problems

Push your limits with challenges.

Question 1

Design a hypothetical CPU flow and describe what happens in detail when an interrupt occurs during the execution of multiple instructions.

💡 Hint: Outline your flow step-by-step to visualize the CPU state transitions.

Question 2

Assume you have a set of instructions executing, and an interrupt occurs while processing a complex operation. Discuss the potential implications of this on instruction integrity.

💡 Hint: Think about what happens if you forget to save your place in a book before being interrupted.
