===Early licensees=== In 1994, Acorn used the ARM610 as the main [[central processing unit]] (CPU) in their [[RiscPC]] computers. [[Digital Equipment Corporation|DEC]] licensed the ARMv4 architecture and produced the [[StrongARM]].<ref>{{cite journal |last1=Montanaro |first1=James |first2=Richard T. |last2=Witek |first3=Krishna |last3=Anne |first4=Andrew J. |last4=Black |first5=Elizabeth M. |last5=Cooper |first6=Daniel W. |last6=Dobberpuhl |author-link6=Daniel W.

This work was later passed to Intel as part of a lawsuit settlement, and Intel took the opportunity to supplement their [[Intel i960|i960]] line with the StrongARM. Intel later developed its own high performance implementation named [[XScale]], which it has since sold to [[Marvell Technology Group|Marvell]]. Transistor count of the ARM core remained essentially the same throughout these changes; ARM2 had 30,000 transistors,<ref name=deMone>{{cite web |last1=DeMone |first1=Paul |title=ARM's Race to Embedded World Domination |url=https://www.realworldtech.com/arms-race/ |website=Real World Technologies |access-date=6 October 2015 |date=9 November 2000}}</ref> while ARM6 grew only to 35,000.<ref>{{cite web |url=https://www.technologyreview.com/article/418585/march-of-the-machines/ |title=March of the Machines |website=technologyreview.com |publisher=[[MIT Technology Review]] |access-date=6 October 2015 |date=20 April 2010 |archive-date=16 October 2015 |archive-url=https://web.archive.org/web/20151016102603/http://www.technologyreview.com/article/418585/march-of-the-machines/ |url-status=dead }}</ref>
