How to read DMA from ADC?

I got DMA working on a MAX 10, from On-chip memory to

On-chip memory. This was a preparation for the real thing:

I have to read 4 bits in parallel from 4 serial ADC's that are

clocked synchronously at 31.25 MHz. Is it possible to perform

DMA from a PMOD connection to On-chip memory? The DMA

should be aware of the 31.25 MHz.

Thanks!
