Testing the core signal processing of the rx side: ~/codec2-dev/build_linux/src$ time ./freedv_rx 700 ~/Desktop/fade700.raw /dev/null
real 0m0.799s user 0m0.795s sys 0m0.004s fade700 is a 60 second file, so that's 0.799/60 = 1.3% CPU. It appears to be using just one core of my 4 core laptop (a modest, 4 year old machine). 700B won't be using any extra MIPs on rx. That's with vanilla C code. The FreeDV GUI program will be using somewhat more, as it's pushing pixels all over the screen.
