ARM Holdings, usually simply ARM, is a British multinational semiconductor and software design company. ARM was spun-off from Acorn Computers in November 1990 as Advanced RISC Machines, Ltd. (ARM, Ltd.) as a joint venture between Acorn Computers, Apple Computer, and VLSI Technology.

Design Groups

Arm processors can largely be grouped into the three design teams that design them in parallel:

• Austin (Texas)
  • Cortex-A8, Cortex-A15, Cortex-A57, Cortex-A72, Cortex-A76, Cortex-A77
  • Neoverse N1
• Sophia-Antipolis (France)
  • ARM11, Cortex-A9, Cortex-A12, Cortex-A17, Cortex-A73, Cortex-A75
• Cambridge (UK)
  • Cortex-A5, Cortex-A7, Cortex-A53, Cortex-A35, Cortex-A55

Microarchitectures
