Challenge Problems
Push your limits with challenges.
Question 1
Imagine a system where the CPU needs to process 10,000 small data packets of 512 bytes each. If using DMA, analyze how different transfer modes would affect processing speed and efficiency.
💡 Hint: Think about how quickly the data can come and go in each mode.
Question 2
Given a scenario with a 32-bit processor needing DMA for 1 GB of data, calculate how many transactions would be necessary based on a 64 KB maximum payload per transaction.
💡 Hint: Divide the overall data size by individual transaction capacity!
