> We already decided to use Marvell's 88F8618 platform,
No clue what that chip is.
> But I have few questions to you and listed it below,

> Q1, Can we implement the Speex Codec on Marvell 8618 for non-HW DSP of
platform?
Care to give the specs?
> Q2, Based on ARM9 CPU core, do you have any information to let me
estimation the voice computing power for Speex codec?
What sampling rate, what bit-rate?
