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

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.<br>

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