ARM, originally
Acorn RISC Machine, later
Advanced RISC Machine, is a family of
reduced instruction set computing (RISC)
architectures for
computer processors, configured for various environments. British company
ARM Holdings develops the architecture and licenses it to some other companies, who design their own products that implement one of those architecturesincluding
systems-on-chips (SoC) that incorporate memory, interfaces, radios, etc. It also designs
cores that implement this instruction set and licenses these designs to a number of companies that incorporate those core designs into their own products.
