Connection between Hardware and NIOS II (Bridges, Streaming)

Hello! I am searching for a fast method to transfer data produced in the Verilog hardware to the NIOS II processor. My ideas are: Using Avalon-MM Slave and Avalon-MM Master in the SOPC buil...

Thank you, direct memory access is definitely what I need!

I instantiated the Scatter-Gather DMA controller in the SOPC builder with the transfer mode "Stream to Memory" and connected the m_write output to the SDRAM and the two descriptor ports to an on chip-memory instance. So, remaining is the port "in" in SOPC builder that I need to connect to an "Avalon-ST source".

Can you tell me what I need to connect this to in the SOPC builder to have an actual input in my Nios module in the Verilog code?
