This is a list of microarchitectures based on the ARM family of instruction sets designed by ARM Holdings and 3rd parties, sorted by version of the ARM instruction set, release and name. ARM provides a summary of the numerous vendors who implement ARM cores in their design.[1] Keil also provides a somewhat newer summary of vendors of ARM based processors.[2] ARM further provides a chart[3] displaying an overview of the ARM processor lineup with performance and functionality versus capabilities for the more recent ARM core families.
