Arm-based processors are a family of energy-efficient microprocessor architectures designed by Arm Holdings, a British semiconductor and software design company founded in 1990 and now owned by SoftBank Group. These processors are widely used across industries such as mobile devices (smartphones, tablets), embedded systems, automotive electronics, IoT (Internet of Things), and data centers. Key products include Cortex-A (application processors), Cortex-R (real-time processors), and Cortex-M (microcontrollers), which power devices from companies like Apple, Qualcomm, and Samsung. Arm's licensable IP model allows manufacturers to customize chips for specific applications, making it a dominant force in the global processor market.
