How do you use the Avalong memory map to interface external memory

I am trying to access data from a DDR4 SDRAM connected to an Arria 10 and store it in a fifo buffer sequentially, and I read that you can use an emif hard memory controller to access the DDR4 memory through the avalong mm interface, but I do not know how I would go about doing it . I am quite new to using FPGAs so any help would be much appreciated.

Hi,

 

You can refer to this Avalon handbook which defines all the Avalon interfaces and how it operate in details --> https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/manual/mnl_avalon_spec.pdf

 

Hope this helps.

 

Regards,
