Question
How many classifications of DMA controllers are made based on the addressing capability?
Solution
DMA controllers are typically classified into two types based on their addressing capability:
-
Single Address DMA Controller: This type of DMA controller uses the same address and data bus for both CPU and peripheral devices. It is also known as a unidirectional DMA controller.
-
Multiple Address DMA Controller: This type of DMA controller has separate address and data buses for CPU and peripheral devices. It is also known as a bidirectional DMA controller.
