The ARM architecture is a 32 and 64-bit instruction set architecture (ISA), based on the reduced instruction-set computing (RISC) design. The 32-bit ARM architecture is the most widely used 32-bit ISA. The ARM architecture is often licensed to other third-party companies, to allow the development of products (e.g. embedded devices, system-on-a-chip designs) with a high degree of binary compatibility, especially with various Linux software repositories.
