Speex dev - Mar 2010 - Speex on EFM32

Hi,

Do you think that Speex could run in real time on the new EFM32 ultra-low
consumption Cortex-M3 MCU (180 ?A/MHz) (NB 8KHz - Quality 4 - complexity 1 /
same as STM32F103 Speex lib.) ?
Its max speed is 32 MHz (about 40 MIPs).

Thanks.

Regards,

Nicolas

You might want to have a look at Speex port from ST Micro. Don't have 
the link, but I think it was posted on the mailing list a few months ago 
(see archive). As far as I can tell, your chip is around the limit 
(don't know which side) of what Speex can run on.

In fact, on my shelf is running speex using Raisonance Primer2 DK and IAR
STM32-SK DK.
But I want to save the power consumption of the device runnig speex, and
EFM32 seems to be a very good candidate.
Also, do yo think that the STM32F103 (Cortex M3 90 MIPS) could be used to
run Speex at 4 Kbps in real time?
