Challenge Problems
Push your limits with advanced challenges
Consider a scenario where a CPU is using programmed I/O to communicate with 5 devices. How might this affect overall system performance, and what alternative approaches could be employed?
💡 Hint: Think about the trade-offs of using one method over another in terms of efficiency.
Given a set of devices using memory-mapped I/O, how would the interaction differ if isolated I/O were used? Illustrate an example with device addressing.
💡 Hint: Consider how addressing schemes influence system architecture.
