hi,

is there any IP to implement DWT and STFT in labview fpga? or a vhdl code for the same( could be fixed point)?

Hi,

What's your use case/ appliation? Could you please tell more?

Thanks!

hi,

There is no application at hand. I am comparing the FFT and DWT implementation speeds, in FPGA,

as compared to non FPGA based approach. so, i just want to create non-stationary signal in labview,

do the DWT in fpga,and get the results back in the the host PC.

You know any links to the code

thnks

OpenCores.org has some cores that could be integrated into LabVIEW using the CLIP node. Here is a link to a DWT meant for images (2D).
