There are currently no mainstream general-purpose [[CPU|processors]] built to operate on 512-bit integers or addresses, though a number of processors do operate on 512-bit data. {{As of|2013}}, the [[Xeon Phi|Intel Xeon Phi]] has a [[vector processing unit]] with 512-bit vector registers, each one holding sixteen 32-bit elements or eight 64-bit elements, and a single instruction can operate on all these values in parallel. However, the Xeon Phi's vector processing unit does not operate on individual numbers that are 512 bits in length.<ref>{{cite web|url=https://secure-software.intel.com/sites/default/files/article/334766/intel-xeon-phi-systemsoftwaredevelopersguide.pdf|title=Intel® Xeon PhiTM Coprocessor System Software Developers Guide|publisher=[[Intel]]|date=November 8, 2012|accessdate=February 8, 2013|archive-url=https://web.archive.org/web/20140710203807/https://secure-software.intel.com/sites/default/files/article/334766/intel-xeon-phi-systemsoftwaredevelopersguide.pdf|archive-date=July 10, 2014|dead-url=yes|df=mdy-all}}</ref>
