Hello,

You can access the SDRAM from FPGA directly through the f2sdram bridge. It should be much faster than the PIO.

You can refer to the DE10-Nano examples from Terasic. They provide an example of how to transfer data from FPGA to HPS and vise versa.

Please let me know if you need further help.

Thank you
