Challenge Problems
Push your limits with challenges.
Question 1
Scenario: A DMA controller is set to transfer 100 MB of data with a maximum transfer unit of 64 KB. How many times will the CPU need to respond to DMA requests during this process?
💡 Hint: Calculate how many blocks of 64 KB fit into 100 MB.
Question 2
Evaluate how switching from interrupt-driven I/O to DMA can affect system responsiveness in a high-load scenario.
💡 Hint: Consider the implications of reduced CPU suspension.
