ARM is a reduced instruction set computing (RISC) architecture licensed by Arm Holdings. It dominates mobile, embedded and, increasingly, server workloads because of its power efficiency. Unlike x86, ARM licenses its instruction set to third parties: SoC vendors like Apple, Qualcomm and Samsung design their own cores around it.

Three main profile families target different compute tiers:

Cortex-A (Application) is the profile of the MPU.

Cortex-R (Real-time) serves industrial and safety-critical systems.

Cortex-M (Microcontroller) is the profile of the MCU.

NVIDIA designs blueprints around ARM, and TSMC fabricates them into the tiny black square of the chip.
