[General] Source Code for DMA Flow Control

[adrian10]

Hi All,
On page 535 in the following user guide, what are the inputs and outputs?

https://www.xilinx.com/support/documentation/user_guides/ug1085-zynq-ultrascale-trm.pdf

By any chance is there any Verilog source code available for the flow control? Or can I refer to any documents for Verilog code?
I wanted to design and verify the flow control for DMA integration.

Any relevant pointer would be very helpful.

Thank you so much!

Thanks,
Adrian
