Hi I looked into the benchmark: I was merely refering to my comparison with a number of algorithms - found on the web - and (en|re)coded by me in my simple implementation.
The gif you refer to does not show, and cannot be opened. But my platform is Linux, with porting to windows. For me my sdr is a kind of digital crystal receiver, where lots of improvements are possible. My math is a little rusty after 40 years, but I am trying, and - most importantly - it is fun. all the best jan 2010/1/31 Alberto I2PHD <[email protected]> > > > On 1/30/2010 7:51 PM, jan van katwijk wrote: > > *This afternoon I downloaded them and will look into it. for ft's I used a > number of > different algorithms, ending up, however, with FFTW, beating all the others > performancewise by miles.* > > Have you looked at the benchmarks where FFTW3 and IPP are compared ?
