Tutorial Vivado UltraScale+ AXI STREAM


I am working on a big project on Zynq UltraScale+ and I need some help in Vivado. My design has 9 inputs AXI STREAM, 8 outputs AXI STREAM, and 2 more variables (double).

I have coded in HLS the PS with the streams but I don not know how to continue in Vivado. I have seen some tutorials with matrix multiplication on ZedBoard (from Gustavo Sutter) but mine is a lot different. I think that I need 17 DMAs (9 inputs + 8 outputs). Is that a good approach? Also I suspect that I need to use the HP ports of Zynq instead of the ACP, but again I do not know how to configure them and how to connect them.


I really need some guidance/documentation.


Any help?

Re: Tutorial Vivado UltraScale+ AXI STREAM

@kostas23 without knowing exactly how you need to use these streams, it's difficult to give a detailed answer but assuming you have 8 pairs of streams as input/output, you can use one dma engine for each so that each can support one pair. Not sure about the purpose of 9th input stream. The variables are just connected to axi-lite slave probably so you can connect it to a gp port.
