32-bit ARM architecture and instruction set
The ARM architectures define a family of RISC processors suitable for use in a wide variety of applications. Processors based on ARM architectures are preferred in designs where a combination of high performance, low power consumption, and small physical size is needed.
ARM Holdings, a British semiconductor and software company, developed the ARM architectures and licenses them to other companies who implement processors in silicon. Many applications of the ARM architectures are system-on-chip (SoC) designs combining a processor with specialized hardware to support functions such as cellular radio communications in smartphones.
ARM processors are used across a broad spectrum of applications, from tiny battery-powered devices to supercomputers. ARM processors serve as embedded processors in safety-critical systems, such as automotive anti-lock brakes, and as general-purpose processors in smart watches, portable phones, tablets, laptop...
