Challenge Problems
Push your limits with challenges.
Question 1
Design a simple CPU model that uses both programmed I/O and interrupt-driven I/O for different tasks. Discuss which scenarios are most appropriate for each method.
💡 Hint: Consider the efficiency needed in different contexts.
Question 2
Discuss the implications of failing to properly restore the CPU context after an interrupt. What are potential real-world effects?
💡 Hint: Think about how critical data consistency is.
