Hi Adrian, The LPCNet codec does have some of the DSP functions ported to NEON as well as AVX, it's a build time option. About a year ago I did some work on getting the codec running in real time on a Pi 3, but it wasn't fast enough. I have been told it runs in real time on some faster ARM

Hi Adrian, On reading the Intel/AMD docs, the AVX/AVX2 additions in the i3 and up do 256bit. ie. 8 simultaneous 16bit number crunches. But the aarch64 NEON, as far as I know only do 128bit. ie. Only 4. I'd look at utilising the other CPU cores, perhaps for alternate frames. Or the GUI. I'm

Hi David, Do you have any idea if we could use any ARM optimizations for 2020 mode? I'm thinking of libvolk which can use SSE3, AVX and NEON and is the backend for GNU radio on ARM platforms. I have an ARM64 board and thinking of trying 2020 on it. Regards,
