What is the most complicated system you've implemented in LabVIEW FPGA?

Hi all.  As the subject implies, I am wondering what the largest, most complicated, sophisticated, etc. system you've seen implemented completely on an FPGA in LabVIEW?  I am trying to get an idea of the use of LVFPGA to compare with a speech recognition project I've been working on for a PXI-7833 target, and get some other ideas on complex system management for FPGA targets.  If you would be ok with your example being mentioned in a school report, please let me know.  Thanks!

Paul,

A good source of community based FPGA examples can be found at

www.ni.com/ipnet

There are a variety of FPGA code examples that have been put up by National Instruments Developers and LVFGA users. It maybe a good resource for what you need.

I hope this helps!

I am currently trying to implement a 2nd order polynomial fit on an FPGA.  Sounds simple but the number of operations it takes it quite large for fixed-point.  I think I have it though.  If I am successful I'll put it on IPnet.

Hello,

I am trying to implement a polynomical on the FPGA with not much luck. I need to keep it to a 32 bit number

basically the polynomial is

Rg = 2 xcubed -445 xsquared + 169x + 286060

where X = A/450 (where A is a value between +-10000)

we already have a big program to implement on the FPGA so space and speed is critical, we cannot afford to have a divide in it and the output needs to be then scaled up to 2 to the power 20.

thankyou.
