MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The Arm Cortex-A processor series is designed for devices undertaking complex compute tasks, such as hosting a rich operating system platform and supporting multiple software applications. Cortex-A32 is a low-power 32-bit only processor with ultra-high efficiency, suitable for the diverse embedded and IoT markets.

Detailed explanation-2: -The ARM processor core is a key component of many successful 32-bit embedded systems. ARM cores are widely used in mobile phones, handheld organizers, and a multitude of other everyday portable consumer devices. The first ARM1 prototype was designed in 1985.

Detailed explanation-3: -With the exception of ARMv6-M and ARMv7-M based processors, there are 30 (or 32 if Security Extensions are implemented) general-purpose 32-bit registers, that include the banked SP and LR registers. Fifteen general-purpose registers are visible at any one time, depending on the current processor mode.

Detailed explanation-4: -The ARM cortex microcontroller is a 32-bit microcontroller therefore all instructions are 32-bit long which is executed in a single cycle. It consists of an instruction set to perform the arithmetic, logical and boolean operations. The ARM is a load-store architecture, then instructions are executed conditionally.
