Overview
The ARM core is probably the most widely used embedded central processing unit incorporated in programmed electronic systems. Millions of products with an ARM core are sold every day. ARM cores are components in so many electronic products that ARM is increasingly chosen as the main CPU example for electronic engineering course. This is an introductory text describing the ARM assembly language and its use for simple tasks. It is suitable for students who have not previously used any assembly language. Features of ARM that differ from other common microcontrollers are emphasised so it is also an introduction for the professional using an ARM device for the first time.
