[Discuss-gnuradio] Re-writing blocks using intel libraries

[Eugene Grayver]

Hello,

We are working on some systems that
require high sampling rates.  I am already using the Intel C++ compiler
at the highest optimization ratio, but a lot of the blocks are very slow
still.  It appears that intel C++ does not properly vectorize <complex>
data type.  

I have been replacing almost every low
level block with a functionally equivalent using the intel performance
libraries (IPP).  These libraries are not GPL, but are free for noncommercial
use under Linux ($200 otherwise).  At some point, I would like to
contribute our work back to gnuradio.  Would this fit with the gr
philosophy?  How should we structure the code?  (i.e. have a
separate set of files, use #defines, or ...)?

Eugene
