avalon-mm dma pcie

[Altera_Forum]

Hello, 

 I am planning to move a large chuck of data between a stratixV fpga and the host computer's main memory. Is it possible to do this through the PCIe with DMA feature IP?  Bests, -Rae

Hi Rae, 

 It is possible. In past, we had successfully transferred data from computer's main memory to Altera's FGPA onchip memory. But at that time we used PCI (not PCIe) with DMA.   Sorry I do not have much idea about PCIe. But if you will do some research, you should be able to find some design doing same as you are planning.  Cheers, Bhaumik

Hi Rae, 

 Please refer this refer design it might help you.  https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/an/an431.pdf

There is a Stratix V Avalon- MM DMA design example on the Altera Wiki:

If you just want to transfer data over PCIe, there are several projects that do so. For example, RIFFA (riffa.ucsd.edu) should work for your board
