+The directory name corresponds to the platform where the samples are built for.

+If you have any problems with installing and/or building the IPP or IPP samples, please read the IPP documentation or contact Intel for support.
+
+==== Running "configure" with IPP support ====
+
+The {{{configure}}} script needs to be invoked with the appropriate IPP options in order to set up IPP include and library paths. There are three relevant arguments:
+
+{{{
+  --with-ipp=DIR          Specify the Intel IPP location
+  --with-ipp-samples=DIR  Specify the Intel IPP samples location
+  --with-ipp-arch=ARCH    Specify the Intel IPP ARCH suffix, e.g. "64" or
+                          "em64t". Default is blank for IA32.
+}}}
+
+
+For this tutorial, we'll use two environment variables to hold the location of IPP and IPP samples. 
+
+Sample configure session for Intel IPP 5.3 for IA32 architecture:
+ {{{
+$ cd /your/pjproject/directory
+$ export IPPROOT=/opt/intel/ipp/5.3.1.062/ia32/
+$ export IPPSAMPLES=~/Desktop/ipp-samples
+$ ./configure --enable-ipp --with-ipp=$IPPROOT --with-ipp-samples=$IPPSAMPLES
+ }}}
+
+Sample configure session for Intel IPP 6.1 for em64t architecture:
+ {{{
+$ cd /your/pjproject/directory
+$ export IPPROOT=/opt/intel/ipp/6.1.2.051/em64t/
+$ export IPPSAMPLES=~/Desktop/opt/intel/ipp-samples
+$ ./configure --enable-ipp --with-ipp=$IPPROOT --with-ipp-samples=$IPPSAMPLES --with-ipp-arch=em64t
+ }}}
+
+Note that you still need to enable IPP support in your {{{config_site.h}}} in order to use the IPP features. This will be explained in the next section.

+==== Download and install Intel Compiler and IPP samples ====
+
+ 1. IPP cannot be obtained separately, you have to install Intel Compiler to get it.
+ 1. Download Intel Compiler and Intel IPP samples from http://www.intel.com/cd/software/products/asmo-na/eng/302910.htm
+ 1. Extract the archive to a temporary folder
+ 1. Run the installer and follow the on screen instructions. The default installation options will install it to ''"/Library/Frameworks"'' directory (e.g. ''"/Library/Frameworks/Intel_IPP.framework/Versions/Current/"'' in my case).
+ 1. Extract IPP samples to a directory (e.g. to ''"~/Desktop/ipp-samples"'').
+
+
+==== Build the IPP samples ====
+ 1. Go to the directory where IPP samples have been extracted to (e.g. {{{~/Desktop/ipp-samples}}}).
+ 1. Go to {{{speech-codecs}}} folder.
+ 1. Open the {{{readme.htm}}} file, and follow the instructions there to build the samples from the source.
+   - typically you'd just need to execute one of the '''build*.sh''' script after setting the IPPROOT environment variable.
+
+The build process produces the following:
+ - (for IPP v5.3) '''{{{libusc.a}}}''' file somewhere under {{{speech-codecs/bin}}} directory. 
+ - (for IPP v6.x) '''{{{libspeech.a}}}''' file somewhere under {{{speech-codecs/_bin}}} directory, e.g. {{{ipp-samples/speech-codecs/_bin/osxem64t_icc111/lib}}} directory. 
 
 The directory name corresponds to the platform where the samples are built for.

 By default, the configuration and build system will link with Intel IPP shared libraries. This is controlled by the {{{IPP_LIBS}}} setting in the auto-generated {{{build.mak}}} file:
