Challenge Problems
Push your limits with advanced challenges
If a DMA is transferring 4MB of data in burst mode and every transfer is 512 bytes, how many times will the CPU suspend its operations?
💡 Hint: Use basic division to find the number of transfers.
Discuss how using cycle stealing can affect the overall time to complete a large data transfer compared to burst mode.
💡 Hint: Consider the trade-off between lower CPU idle time versus increased transfer duration.
