Show hintHide hint
Think about what direct memory involves.
4Question 4.
True or False: DMA operation requires constant CPU attention during data transfers.
- True
- False
Show hintHide hint
Consider the role of the CPU in traditional I/O methods.
Question 5.
A computer system is designed with multiple I/O devices all attempting to use DMA at the same time. Discuss how the system might manage conflicts when multiple devices request bus access.
Show hintHide hint
Think about how traffic is managed at busy intersections.
Question 6.
You are tasked to design a new DMA controller for a high-speed data application. What key features must your controller have to ensure efficiency and reliability?
Show hintHide hint
Consider what features would enhance both speed and safety in data transfer.
