Challenge Problems
Push your limits with advanced challenges
You have a system using DMA to transfer 100MB of data. If the cycle stealing mode transfers 1KB at a time, how many interruptions occur during the transfer?
💡 Hint: Convert MB to KB to simplify calculations.
Design an experiment to compare the performance of burst mode vs. cycle stealing in a real-world application.
💡 Hint: Focus on measuring transfer times and CPU idle periods.
