How to write user logic to control SOPC DMA controller?

Could you give more details or examples on how to write to the registers?

Where can I find DMA register's address? where I can find more information about DMA's control port slave?

The DMA core manual says "An Avalon-MM master peripheral sets up and initiates DMA transactions by writing to registers via the control port. The master peripheral then sets a bit in the control register to initiate the DMA

transaction."

Thank you very much!

Have a look at the avalon specification (http://www.altera.com/literature/manual/mnl_avalon_spec.pdf). It describes all the signals and timings in Avalon busses.

You'll probably need to write a state machine that can write all the registers one by one.
