NI 1473R dual frame acquisition

[mesolmaz]

Hi all,

I am trying to modify the "10-tap 8-bit Camera with DRAM (FPGA).vi" example to simultaneously grab two frames (original and processed) from NI-1473R LX110. I have created extra FIFOs, data packers. I am trying to write two frames to DRAM at the same time but I don't have any control over the location/address. I can just select upper/lower banks. 

My question is: is this doable? Or do I have to use a memory with different addresses?

I have read in other NI threads that for high speed applications, packing the data to DRAM works much better than using other defined memory. 

Obviously it is flawed but my example is attached.

Hey mesolmaz,

I'm glad you started with the examples because I looking through them I believe all you would need to do is write one image to the upper and one to the lower.  You will be limited to 256 MB per image at that point and you'll have to troubleshoot the splitting the FIFO nodes that are in the example, but I see no reason off the bat that you can't do it.  To the FPGA they are two separate memory spaces that you can keep track of location.
