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 ...)?
