Are DMA transfers from PXI-6608 to PXI-7831R possible?

[bwbarnes]

I am trying to shed some of the workload off of my FPGA (running out of realestate) and I would like to know if the following is possible.  I need to measure the time between two rising edges for feedback in a control loop.  I have a PXI-6608 counter and a PXI-7831R FPGA.  Is there a way that I could use the counter to measure the time interval and report that interval to the FPGA at a rate of 20kHz?  I was thinking that a DMA transfer would be able to accomplish this but I'm not sure how to implement it in LabVIEW FPGA.

Hi bwbarnes,

You can write to the DMA FIFO on the FPGA itself given you have LabVIEW FPGA 8.2 or above.  This is described here.  A general example on how to use DMAs is explained here.  Note that the second link is from FPGA to Host.
