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? Regards, Nicolas 2010/3/3 Jean-Marc Valin <jean-...

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 -------------- next part -------------- An HTML attachment was scrubbed... URL:
