In electronics, ARM stands for Advanced RISC Machines Ltd., referring to a microprocessor architecture developed by UK-based electronics company ARM Holdings plc.
The ARM architecture is known primarily as a low-power processor technology that is widely used in mobile devices and embedded systems.
ARM processors are characterized by low power consumption, high performance, efficient instruction set, and easy programming interface.
Because of these characteristics, ARM processors are widely used in mobile devices and embedded systems, such as smartphones, tablets, handheld game consoles, and Internet of Things (IoT) devices.
The ARM architecture has various versions and lineups, and representative ARM processor series include ARM Cortex-A, Cortex-R, and Cortex-M.
Each series offers a design and performance optimized for specific applications and requirements.
The Cortex-A series is mainly used for high-performance applications, the Cortex-R series for real-time systems, and the Cortex-M series for low-power embedded systems.
ARM processors are based on a concise and simple instruction set architecture (RISC) as opposed to traditional complex instruction set processors (CISC).
This helps improve the design and execution efficiency of the processor.
In addition, the ARM architecture provides a variety of circuit design and software development tools to help developers develop easily.
