Challenge Problems
Push your limits with challenges.
Question 1
Design a simple system that uses both programmed I/O and interrupt-driven I/O, detailing how each method will be employed.
💡 Hint: Consider which devices require constant checks and which can notify the CPU only when action is needed.
Question 2
Discuss the implications of using memory-mapped I/O in a system with numerous I/O devices versus isolated I/O.
💡 Hint: Think about how many devices can realistically be connected in both scenarios and the impact on system performance.
