In the world of digital embedded systems, the ARM Cortex is a most famous microcontroller. And most of the applications used in the industries choose only these microcontrollers. Since it comprises of vast features to implement products with an innovative appearance. The ARM processors are high performance and cost sensitive devices which are used in an extensive range of application like instrument control systems in industries, sensors, wireless networking and automotive body system etc.
The term ARM stands for “Advanced RISC machine” and it is a 32-bit RISC (reduced instructions set computer) microcontroller. In the year 1987, the first ARM processor was introduced by the “Acron Computers” organization.The ARM belongs to the microcontroller family developed by the different industrialists like Motorola, ST microelectronics, and so on. The architecture of ARM cortex come with a few different forms such as ARMv1, ARMv2 etc and each type of ARM has its own advantages and disadvantages.
