TBH I'm not sure. Further optimisation in this area (e.g. on the LPCNet code, other SIMB instruction sets) is possible. However it's not an area I am interested in working on. I have asked others to step up and work on it but no takers. Even with AVX, there have been reports of easily overloaded CPUs (e.g people running SDRs on the same machine). This is highly experimental radio. What I do want to avoid is support issues from people running it on non-accelerated hardware. Modes like FreeDV 2020 are experimental enough, without the additional challenge of borderline hardware. The way we are handling it is to disable 2020 operation in freedv-gui if no AVX is detected. So I would discourage anything (like packaging) that would suggest LPCNet can run without SIMD. If someone is competent enough to build it themselves and wish to experiment on non-SIMD machines, then that's fine.
