By Zinedine The ARM architecture has rapidly become a dominant force in computing, powering everything from smartphones and tablets to servers and embedded systems. Its energy efficiency, scalability, and cost-effectiveness have made it a compelling choice for a wide range of applications. This article delves into the intricacies of the ARM architecture, exploring its design principles, key features, and the robust support it enjoys from the Linux operating system.
Understanding the ARM Architecture
At its core, ARM stands for Advanced RISC Machine, highlighting its foundation in Reduced Instruction Set Computing (RISC) principles. Unlike Complex Instruction Set Computing (CISC) architectures like x86, RISC architectures employ a smaller set of simpler instructions, leading to faster execution and improved power efficiency. ARM processors are known for their load-store architecture, where data must be moved between memory and registers before being processed.
