Challenge Problems
Push your limits with advanced challenges
Design a simple interrupt handling mechanism for a device in a system where both software and hardware polling are used for identifying interrupts. Describe how conflicts are resolved.
💡 Hint: Think about how you would visualize both methods in tandem.
Imagine a scenario where multiple devices have sent interrupts simultaneously. How would you design a follow-up ISR that allows the CPU to manage these without missing any?
💡 Hint: Consider how to keep track of multiple requests in an orderly manner.
