Hi all,
ARM announced the successor to the Cortex-M4, the Cortex-M7. It has twice
the CPU speed (400MHz), a double precision floating point unit, and better
caching. It's focused on better DSP. Looks sweet!

And
Cortex M7 would go in SmartMic without modification, it appears,
which means there would be extra power to run the Speex audio
preprocessor, better battery life, etc. (although just maybe the
Speex audio preprocessor could work in the present chip).
I also wanted to
A small suggested modification / enhancement for freedv.
Since the call sign is transmitted at all times when I key the TX,
a useful feature would be a log entry (file) logging time, call, and
possibly SNR,
when getting a synched carrier.
Reading this file from a unattended freedv station,
Yes, it was even mentioned in a WSJ (wall street journal) article today. :-)
I guess they expect it to make some $$

Hello Gullik,
That is a good suggestion, thanks. I have also been working on a system
to parse text messages and fire of system calls, for example to post
spots and other information to web servers. This is running the freedv-dev.
Cheers,
David
