Hi Everyone,
I've expanded my comparison of FFT performance in Ultrascale to include
some new FFTs.
You can see the plots at https://bxbfft.com/Ultrascale.html.
The comparison now includes
Astron FFT from opencores.org
BxBFFT https://bxbfft.com
CAStron FFT https://github.com/talonmyburgh/casper_dspdevel.git
htfft https://github.com/benreynwar/htfft.git
SGen FFT https://acl.inf.ethz.ch/research/hardware/
Spiral FFThttps://www.spiral.net/hardware/dftgen.html
Xilinx SSR FFT in Vitis
ZipCPU FFT https://github.com/ZipCPU/dblclockfft
It doesn't include the original CASPER FFT, since I don't know how to
get RTL source code for it. It doesn't include other commercial FFTs
for the same reason.
If anyone knows of other FFTs that I should include, or other ways that
I should compare FFTs, let me know.
I also have plots up for FFTs in Xilinx Versal and for FFTs in various
Altera FPGAs, but those plots don't currently include as many FFTs.
I'll update them as I have time.
Regards,
Ross
