Honored ContributorSGDMA to SDRAM speed?
[EDIT] SOLVED
Hello, I'm trying to develop an accelerator for a computer vision algorithm. The host program is running on the Intel Atom on the DE2i-150 board, and is sending images to the FPGA for processing. The problem is that I can't get more than 3 to 10MB/s throughput, which is quite small since the PCI-Express should be able to deliver something about 250MB/s, and the SDRAM should be even faster. My QSYS is pretty simple, you could see it on the attachment. I would appreciate if someone could help me with this. Is that a common issue? Can I be able to get more speed, something like 90MB/s or so? If so, how could I accomplish that? Many thanks.31 Replies

RIFFA should work for any of the Altera PCIe development boards -- If it's not included in the RIFFA distribution, it's just because we haven't tested it -- ping me and I'll help you out. riffa.ucsd.edu and https://github.com/drichmond/riffa
