Versions(all)

ARM Versions are the architectural version numbers. ARM architecture versions always use the ARMv# notations. Architecture versions are often confused with the various ARM implementations which historically used similar notations ARM#. Note that for the implementations, the number does not necessarily correlates to the architecture version used. Over the years, a number of additional implementations were designed by third party companies such as DEC, Intel, Qualcomm and Apple.
