Question 1.
What does Memory-Mapped I/O simplify?
Show hintHide hint
Think about how peripherals and memory are related.
Question 2.
What does DMA stand for?
Show hintHide hint
Recall the functionalities of the processor.
3Question 3.
What is the primary function of Memory-Mapped I/O?
- A. It allows interactions between CPU and memory only.
- B. It simplifies communication with peripherals by mapping them to memory addresses.
- C. It replaces traditional I/O ports with hardware adjustments.
Show hintHide hint
Recall how peripherals are treated in programming.
4Question 4.

- True
- False
Show hintHide hint
Consider the role of the CPU in managing data.
Question 5.
If you had to design a simple embedded system using Memory-Mapped I/O, what considerations would you take into account regarding address allocation for peripherals?
Show hintHide hint
Think about what happens if two devices want the same address.
Question 6.
Investigate how implementing DMA in a system with Memory-Mapped I/O could impact overall system performance and responsiveness.
