Arria 10 DDR4 external memory interface

Hello NAli1_Intel,

Thank you for the reply. Thank you for the reference documents.

1) If Avalon DMA IP only access 128 MB of external DRAM, is it beneficial to use it for Arria 10 GX board which contains 2GB on board DRAM?

2) In the document https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/arria-10/a10_overview.pdf, page 22, it is mentioned "Intel Arria 10 devices offer massive external memory bandwidth, with up to seven 32- bit DDR4 memory interfaces running at up to 2,400 Mbps". Does it mean the bandwidth between Arria 10 and one channel of DRAM is 32 x 7 bits?
