Challenge Problems

Push your limits with challenges.

Question 1

Consider a system that uses burst transfer to transfer 10 MB of data. If the maximum transfer size is limited to 64 kB, how many complete transfers are necessary?

💡 Hint: Convert MB to KB before division.

Question 2

Design an optimal data transfer system using DMA for a scenario where multiple devices need to send data to memory. What configurations would you consider and why?

💡 Hint: Think about the trade-offs between single and multiple DMA controllers.
