You need to download IPP for IXP and take IPP samples (please visit IPP samples page, available from IPP home page).</P> <P>We will be glad to hear any feedback from you about usability, functionality and performance of codecs, IPP functions and samples.</P> <P>Regards,<BR /> Vladimir</P> <DIV></DIV> Mon, 27 Feb 2006 22:29:40 GMT https://community.intel.com/t5/Intel-Integrated-Performance/Image-processing-on-PXA-with-Linux/m-p/943655#M17919 Vladimir_Dudnik 2006-02-27T22:29:40Z
