Question 1.
What does DMA stand for?
Show hintHide hint
Think about the type of memory interaction.
Question 2.
What happens in a burst transfer mode?
Show hintHide hint
Consider the difference from cycle stealing.
3Question 3.
What is the main advantage of DMA over interrupt-driven I/O?
- It allows for faster data processing
- It eliminates CPU involvement
- It increases CPU wait times
Show hintHide hint
Think about how each method engages the CPU.
4Question 4.
True or False: In burst mode, the CPU gets suspended for shorter periods than in cycle stealing.
- True
- False
Show hintHide hint
Recall the definitions of both modes.
Question 5.
Design a system that uses DMA and analyze the potential efficiency gains over an interrupt-driven system.
Show hintHide hint
Think about how much time CPU could have lost during interrupts.
Question 6.
Compare and contrast the use of DMA with interrupt-driven I/O in the context of system design for a real-time application.
Show hintHide hint
Select examples of each to illustrate the differences.
