integrating fpga module with standard block diagram

[Zzzyzx]

Hi all,

I'm doing an FTIR multitouch table, and I would like to be able to track blobs using LabVIEW then transfer this data to a Spartan 3e FPGA.  I have seen the tutorials on how to program the Spartan 3e and have direct communication with LabVIEW, but can I also run image processing via USB-IMAQ VIs in the same block diagram?  Basically I need to get coordinate data from the blobs (touch points on the screen) and transfer this data to an FPGA which will act as a primitive graphics card.  Any ideas are appreciated.

Thanks...

Zzzyzx,

Hello! You should be able to use your Host VI to talk to Both the FPGA and the USB-IMAQ devices. You would just have two loops running at the same time, one for each device's communication. To pass data between the loops (from the vision to the FPGA) you could use a Consumer Producer Architecture.

I assume you are referring to these tutorials?
