[Asterisk-Dev] Intel Open Source Fast Math Library

I'm sure the developers that would use something like this are already 
aware of it, but just in case this may be of use in the dsp/echo 
canceler area of Asterisk on PIII/IV CPU's.

It is the Approximate Math library on the page

http://developer.intel.com/design/Pentium4/devtools/

and according to

http://www.intel.com/cd/ids/developer/asmo-na/eng/microprocessors/ia32/pentium4/optimization/19036.htm?page=1

"As the "Open Source" tag implies, the AM Library is completely free and 
does not require a license to use."

It is quite probable that most of these functions are of no use or the 
fixed point implementations currently in use offer better performance.

Regards,

Richard
