   1st in Xscale is integrated Micro Signal Architecture (MSA), the
new design incorporates DSP and microcontroller functions - Intel and
Analog Devices joint development design a digital signal processor
(DSP) core architecture. 
   All speech, audio and video codecs like G.729, G.723, G.726, G.728,
GSM, MP3, MPEG-4, etc. are optimized for Xscale architecture using
integrated DSP functionality.

   2nd we are not care about host CPU Speech coding because we are in
process of development of USB/PCI Device named Multimedia Transcoder
(MMT) which will handle simultaneously from 16 up to 256 Codecs. This
codec will be available Apr-May 2005. The price will be between $400
and $1000. Using this MMT you can use 50 MHz CPU for Asterisk.
