[Speex-dev] Speex for TI MSP430 microcontroller - estimating CPU speed requirements?

<html>

Hello Jean Marc:<br><br>
Please see the email I just <font color="#FF0000"><b>re
</b></font>sent
to David (several serious typos in my original email to him ... sorry). I
came to the same conclusion that you expressed below. The MSP430xx does
have a MAC, but no compute pipeline.<br><br>
