Push your limits with advanced challenges
A file of size 10 MB is to be transferred using DMA in burst mode, where the maximum data count is 128 KB. How many burst transfers will be required?
💡 Hint: Break down the total size and see how many chunks fit into the maximum size.
In a system where interrupt-driven I/O management is used, what are potential bottlenecks resulting from frequent interrupts?
💡 Hint: Think about how many times the CPU has to give up its work for handling the interrupts.
