How to use SDRAM on de2-70 board?

Hi everyone,

I would like to ask any idea how to transfer data from verilog to NiosII for processing and transfer back to verilog again? Recently, I work on video processing project, the data is from the TV decoder (after converting to RGB/gray scale), required to transfer it to NiosII for processing. After processing is finished, the data is again transferred back to verilog for VGA display. Anyone can show me some simple example design how to transfer data to NiosII and transfer back to verilog by using avalon bus? Thanks a lot and I will appreciate it.

Best regard,
