ciaby ciaby at autistici.orgThis patch just convert read/write into fread/write, which are buffered and a bit faster... (actually, quite a lot faster) :-) It works, have been tested at the CCC, and allow osmo-tetra to run in real-time on a crappy Atom CPU. Btw, if you like to run the entire decoding chain in real-time, just do this (assuming that you use the funcube dongle): cd src/demod/python mkfifo out.float mkfifo out.bit ./fcdp-tetra_demod.py -D hw:1,0 -c <offset> -o out.float //(normally the fcdp runs on the second alsa port, change it to the appriopriate one). ../../float-to-bits out.float out.bit ../../tetra-rx out.bit I'm still not 100% sure about the speech decoder, but i don't have any good sniffer dump with speech traffic to test it, i will let you know in a week or so... Happy hacking! :-) Ciaby P.S. I have a plan to convert the float-to-bits code into a proper GNU Radio module, shouldn't be too difficult, is there any interest into continuing this project? As I understood Harald is quite busy with other stuff (and rightfully so), but I think that we should move forward. Volunteers? ;-) -------------- next part -------------- A non-text attachment was scrubbed...
