[Freetel-codec2] Resources used by stm32f405VG

[Nouman Khalid/A-XEN R&D/NRTC]

Hi all,

I want some information about codec2 and sm1000. As codec2_encode_1600() says it converts 40ms of speech signal into 64 bits. What are the resources utilized by stm32f405VG to make 8 frames of that 64 bits? Or how I can calculate the resources being utilized by the stm32f4 in this environment ? Experts opinions needed please

Regards
Nauman

Hi Nauman
The best way to do this is to run the code up yourself.

You will need to learn how to use the debugger and profiler. You will
need to do this yourself to be able to make your own modifications,
there are no shortcuts.

That will give you the real numbers.

Alternatively, simply count the machine cycles from the assembler code.
That's easy.

regards

Hello Nouman,

Codec2 is an Amateur Radio project. We don't wish for Amateur Radio to be
viewed as dangerous by the many nations that host it, or for digital voice
codecs to come under export restrictions. Thus, we must not support
military development of our technology. This is the mutual conclusion of
the core developers with whom I've discussed the issue. We ask that you
respect this decision and not come to the mailing list with questions. Nor
will we support military development by the United States or any other
nation on this list - they have the resources to help themselves. Obviously
the code is Open Source and we can't stop you from using it.

Thanks

Bruce
