Hi All,
I have read that LabVIEW and LabWindows/CVI uses a highly efficient Cooley-Tukey mixed-radix FFT algorithm. But I want to make sure wheather the LabVIEW FPGA (my FPGA is cRIO-9074) is also using the Cooley Tukey Algorithm? I also read that the FPGA cannot use floating point arithmatic, so I would like to ask if the FPGA using any integer FFT (intFFT) algorithm? I would like to know how the LabVIEW win the challenge of using both integer FFT and Cooley Tukey algorithm? (Or is the Cooley Tukey algorithm itself is an intFFT?)
Please consider my question is only regarding LabVIEW FPGA or in otherwords about the FFT Express VI.
Thank you

Can't help you with your FFT questions, but LabVIEW FPGA does support floating point arithmetic since 2012 (http://www.ni.com/white-paper/14188/en/).
