Challenge Problems
Push your limits with advanced challenges
You need to design a system that can efficiently handle the transfer of a 10 MB video file from a capture device to memory using DMA. Describe the setup and transfer protocol you would propose to minimize CPU interruption.
💡 Hint: Think about structured data pathways and access management.
Given a 32-bit processor, calculate how many interrupts would occur while transferring a 20 MB file using burst mode without optimization. Describe the expected performance impact.
💡 Hint: Reflect on memory limits and transfer sizing.
