Arm architecture is a family of computer processor designs developed by Arm Holdings. It is widely used in mobile devices, embedded systems, and increasingly in servers and personal computers due to its energy efficiency and performance. The architecture is based on a reduced instruction set computing (RISC) model, which simplifies the instructions that the processor must execute. One of the key features of Arm architecture is its ability to support a wide range of applications, from smartphones to Internet of Things (IoT) devices. Its modular design allows manufacturers to customize processors for specific needs, making it a popular choice for developers looking to optimize performance and power consumption.
