Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What is the main advantage of DMA over interrupt-driven I/O?

  • The CPU is never suspended
  • The CPU is suspended less frequently
  • Data transfer is slower

💡 Hint: Think of how efficiently the CPU can continue working during transfers.

Question 2

True or False: In burst mode DMA, the CPU can access the bus during data transfer.

  • True
  • False

💡 Hint: Consider what happens during continuous data transfer.

Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
