Thanks for your reply.

The number_of_data defines the memory for ADC data. In my test design, only part of the memory are used. The number_of_buffer and length_of_buffer represent the number of descriptors in the descriptor list and number of bytes transmitted for one descriptor respectively.

So the defination is OK.

I don't need to continuously smple, just sample several MB bytes and then stream out .

Now, SGDMA is the bottleneck of my design. I'm really confused.
