Which DMA transfer mode will be preferred for memory to memory data transfer: Justify with timing diagrams. Find approximate values of the data transfer rates that can be achieved if the given clock frequency is 100 MHz in different modes.

 

Depends on the DMA Controller. What are the choices of mode?

 

I think this homework expects you to open your notes on the subject and find what the answers are. Suggest finding what those modes are and how they work.
