An ARM processor is a type of computer chip designed for high efficiency and low power consumption. Originally developed by ARM Holdings, these processors use a simplified instruction set architecture (RISC) that makes them ideal for mobile devices like smartphones and tablets. Their energy efficiency has led to widespread adoption in embedded systems, Internet of Things (IoT) devices, and more recently, laptops and headsets such as the Steam Frame. ARM processors are valued for their balance of performance and battery life, making them a popular choice in modern electronics.
