'''ppc64le''' is a pure little-endian mode that has been introduced with the POWER8 as the prime target for technologies provided by the OpenPOWER Foundation, aiming at enabling porting of the x86 Linux-based software with minimal effort.<ref>{{cite web | url = http://www.novell.com/docrep/2014/04/sles_12_on_ibm_power8_faq.pdf | title = SUSE Linux Enterprise Server 12 on IBM POWER8 | date = February 2014 | accessdate = August 12, 2015 | website = novell.com | archive-date = August 16, 2014 | archive-url = https://web.archive.org/web/20140816070508/http://www.novell.com/docrep/2014/04/sles_12_on_ibm_power8_faq.pdf | url-status = dead }}</ref>
