Types of DMA Controllers?

[er.akhilkumar]

Can anyone please share what are the types of DMA Controllers? For example: Multi-channel DMA, Single channel DMA etc.

It will be nice if you can point me to some good document regarding above topic.

Thanx

I know basics of DMA. I want to know the types of DMA Controller. Wikipedia doesn't contain that info.

I don't agree with you. It definitely contain info about different types of controllers. It doesn't mention single/multi channel because that's not very interesting.

Try to search the web (https://duckduckgo.com/?q=dma+controller&t=lm) and read some of the documents you find.
