Hello, I need the information about DMA on sbRIO board.
We use sbRIO 9606 and the board can communicate with host PC and FPGA target via DMA.
Just my colleague is curious that where the DMA's memory locates. Does the memory locate on FPGA chip?
I mean, the Xilinx chip has memory area (FIFO area) for DMA transfer? Or peripheral circuit is existed?
From the knowledgebase; http://digital.ni.com/public.nsf/allkb/0A008919E1551B1A86257B9D00764FC4
sbRIO has 5 DMA channels.
The LV help has a diagram but it does not answer my colleague's question.

I checked Xilinx website also, but I couldn't reach the answer.
sparten-6 LX FPGA has 5 memory interface controller blocks and I am guessing that are DMA transfer memory. Is it correct?
Even though, I can not reach the answer for physical location on FPGA board. The top diagram on page 4 of the following looks good but not answer for my question;

We look forward to get the reply for this issue.
