asterisk users - Mar 2006 - Which g729 codec to download for a P4?

Sorry for being a bit of a newbie here but I find the
docs or README for downloading the G.729 codec from Digium
are not as detailed as I would like or just don't really
break down the different versions to a point that I am clear
on which one to grab.

The choices for 32bit are:

drwxr-xr-x    3 0        0            4096 Dec 05 00:21 athlon-xp
drwxr-xr-x    3 0        0            4096 Dec 05 00:21 c3
drwxr-xr-x    3 0        0            4096 Dec 05 00:21 c3-2
drwxr-xr-x    3 0        0            4096 Dec 05 00:21 i386
drwxr-xr-x    3 0        0            4096 Dec 05 00:21 i586
drwxr-xr-x    3 0        0            4096 Dec 05 00:21 i686
drwxr-xr-x    3 0        0            4096 Dec 05 00:21 k6-3
drwxr-xr-x    3 0        0            4096 Dec 05 00:21 pentium-m
drwxr-xr-x    3 0        0            4096 Dec 05 00:21 pentium3m
drwxr-xr-x    3 0        0            4096 Dec 05 00:21 pentium4m
drwxr-xr-x    3 0        0            4096 Dec 05 00:21 prescott


I'm unclear if "athlon-xp" is only for athlon xp or all
athlons/durons
if not what is best for athlons & durons?
I will need to install g.729 on a duron server soon.


But immediately I need to install g.729 on our P4 server
and I'm a little confused on 'which p4' I need to install.

What is the 'm' for in pentium4m?
seems to mean 'multi' processor but I am totally unclear on this.
what the heck is just a 'pentium-m'?
Thanks for your help.

I apologize for the rediculousness of this question, but was hoping to find
a chart on which preocessor is what in the README.

I have a pentium4 server but do not understand how to quickly tell if I
have a pentium4m a prescott or an i686

I 'think' it's a wiliamette just by clock speed and wild guessing
from
memory about the time the variouss cores came out but that's it!

Here's what the kernel says:

 cat cpuinfo
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 15
model           : 2
model name      : Intel(R) Pentium(R) 4 CPU 2.40GHz
stepping        : 7
cpu MHz         : 2392.146
cache size      : 512 KB
fdiv_bug        : no
hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes

wp              : yes

cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid
bogomips        : 4734.97



Thanks & take care!

Steve

And also curious why a K6-3? but not a K6-2?
And then of course why do we get a K6-3 but not an Athlon?

The 'm' in x86 architecture CPUs usually refers to a 'mobile'
optimized
version of the CPU. That usually means it consumes less power and may have 
the ability to switch CPU speeds while in use (e.g. Intel's SpeedStep 
technology). The Pentium-M is the CPU that is part of the Intel Centrino 
chipset (CPU+wireless+north/southbridge package), and it's the direct 
decendent of the Pentium-3.

Chosing a cpu-specific version of the codec simply means you will be using 
one that is was compilied targeting that cpu, and it may use cpu 
instructions only available on that cpu or its decendents. You can always 
choose a version from a architecture-lineage precedessor, and for any x86 
cpu available today, that means the i386. The tradeoff for a more generally 
compatible version is a potentially lower performing codec, but this should 
not be a problem unless you are pushing your system to the limits.

If I remember by CPU history for the Pentium 4 correctly, you should be 
safe with any of the i386/i586/i686/pentium3m/pentium4m options.

There is a good chart here:
http://en.wikipedia.org/wiki/List_of_Intel_microprocessors
and more:

I remember I head the same issue. I don't know why they don't put txt
file with explanation?! Next time I need their codec I'll definitely write
them that suggestion.

Anyway, I have used i386 for P4.
