Id like it too see more testing. But I hope to get it in gnuradio. The implementation is relying on a hairy thing like swig directors.

Id like to point out that the adder implemented w/ numpy could be performing arithmetic faster because thats vectorized and until we use volk, the adder in gnuradio C++ is not. The real overhead probably comes from the memory allocations that happen going between python and C++ and making python objects. I havent benchmarked it, but I am guessing its non-trivial. > On the other hand (I think I've run out of hands...), this also goes a long > way to solving the problem of people wanting a Matlab interface system.

Let us know how you want to continue to support it. > Yes: I want to support proper message passing. I noticed that I can register a message handler to receive messages. Can you point me to how messages are produced? I really hate gr_tag_info.h. I would rather get_tags_in_range filled a vector of type tag_type, where tag_type has methods like .get_key(), .get_value(), etc... Basically im complaining that we didnt use object orientedness here when its realy well suited for it. You will see that I did this wrap-around in my pyblock_gateway so I didnt have to swig tag_info. See the tags_demo.py to see how I used it. _josh _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
