Nice work, Miroslav. I wanted to point out our VOLK project that's part of GNU Radio. It's designed to abstract SIMD instructions. We don't have that much support for NEON right now, but VOLK is designed in such a way that if you're using VOLK kernels, it'll fall back to a generic implementation until such time as the kernel is written for the particular architecture. You can get more info on the project here: http://www.trondeau.com/blog/2013/6/12/nearly-50-minutes-of-volk.html http://www.trondeau.com/blog/2012/2/13/volk-integration-to-gnu-radio.html -- Tom Visit us at GRCon13 Oct. 1 - 4 http://www.trondeau.com/grcon13 > -- > Miroslav Slugeň > +420 724 825 885 > > Teramos Multimedia s.r.o.
