I am trying to access this project ( http://opencores.org/cvsweb.shtml/fftprocessor ) , I know it is an old project and maybe it has been deleted now . But I really need this specific source code for FFT processor .
if anyone already have the source code or if the URL has changed it would be a great help for me . Thanks

Some years ago, a copy was made of everything on OpenCores, as it wasn't certain whether OpenCores would remain and would remain viable. With a little Google, I found a copy of the "fftprocessor" project you are looking for here on FreeCores on GitHub.

Thank you very much , that was really helpful

Ooh hey, awesome. Good to know. I found OpenCores earlier in 2016 but it hasn't seemed like a lot has gone on since that time.

Thanks for sharing! I, too, appreciate it.

Nah, there hasn't been much going on in a while. I'm told the site is now under new ownership, but ... we'll see if the new owner wants to announce him/her self ... :D

P.S. I've been starting to blog at zipcpu.com about my experiences building open (GPL) cores. The blog so far has focused on how to debug an FPGA, but I have grand plans. Feel free to come visit.

I've even thought about making a big announcement sometime soon here about it ...

Hmm ... for some reason my http: href's above are getting turned into https: references that then get insecurity warnings. ZipCPU.com doesn't have any https support at this time--hence the warning. I just can't figure out why my links are going to the https port instead of the http port ...
