Introduction

ARM is the dominant processor architecture in mobile and embedded devices. The CPU architectures are developed by ARM Ltd. and licensed by various hardware manufacturers for use in processor design. Plenty of ARM-based processor models are available on the market, ranging from special-purpose microcontrollers to generic computing with support for consumer operating systems. The price-performance ratio and broad availability makes ARM processors ideal for use in hobbyist electronics projects.

History

The initial ARM processor architecture was developed in the mid-1980s by the British computer manufacturer Acorn Computers with the goal of creating an auxiliary processor for a business computer product. The acronym ARM stands for Acorn RISC Machine. ARM Ltd. was founded as a joint venture with the U.S. computer manufacturer Apple with the goal of developing an improved architecture that could be used for the main processor of a computer.

Cross-Compiling

If your operating system is Ubuntu Linux, running on an x64/AMD64 processor, you need the following package to cross-compile code to run on ARM Cortex series processors:

sudo apt-get install gcc-arm-none-eabi


Microcontrollers

ARM's family of Cortex-M processors (notably M0, M0+, M3, M4) are designed for use as energy-efficient microcontrollers, where M0+ is the cheapest and most efficient, and M4 is the fastest and most capable (offering DSP functions and a floating point unit).
