Speex dev - Jun 2006 - Speex Codec Question

Hello,

I am Janus of QMI?s PLM,

We would like to implement the Speex Codec in our embedded system for VoIP
Product application,

Therefore, I have few question and listed it below,

Q1, how much of MIPS we need to reserve the system computing power for Speex
Codec needed?

Q2, do we need to use the voice DSP for Speex Codec needed?

 

Sorry to bother your job

 

Best Regards

It greatly depends on your chip. Some numbers I've had on the latest
version (svn) are about 30 MIPS on ADI Blackfin and about 40 MIPS for TI
C55x and C6x DSPs. That's at 15 kbps narrowband, complexity 1. Other
settings will change the complexity.

Sorry, could you rephrase your question?
