Hi Sir,

Good day to you.

Intel offer PCI Express DMA Reference Design Using External Memory that uses an external memory connected to the Intel memory controller that can access up to 128 MB of on-board external memory. The read DMA moves the data from the system memory to the external memory. The write DMA moves the data from the external memory to the system memory.

You may refer to page 10 of this handbook for more details on how to run the reference design.

You may also refer to this Intel wiki page where user can download the Arria 10 Gen3x8 AVMM DMA reference design with DDR4 controller to access external DDR4 on board memory. Hope this is helpful.

Thanks.
