A characteristic feature of ARM processors is their low electric power consumption, which makes them particularly suitable for use in portable devices. In fact, almost all modern mobile phones and PDAs contain ARM CPUs, making them the most widely-used 32-bit microprocessor family in the world, more so than the better-known 32-bit Pentium 4 processors found in many PCs. Today ARMs account for over 75% of all 32-bit embedded CPUs.

ARM was a spin-off from Acorn Computers Ltd, intended to further the development of the Acorn RISC Machine's RISC chip, which was originally used in the Acorn Archimedes and is now the processing core for many custom ASICs. ARM processors are used as the main CPU for many Personal digital assistants (PDAs) and handhelds, like the Apple iPod, Nintendo Game Boy Advance and Gamepark GP32.

Unlike other microprocessor corporations such as AMD, Intel, Motorola and Hitachi, ARM only licenses its designs, rather than manufacturing its own CPUs. Thus, there are a few dozen companies making processors based on ARM's designs.
