ARM64

ARM64, also known as AArch64, is the 64-bit extension of the ARM architecture, a reduced instruction set computing (RISC) ISA. It was first introduced with the ARMv8-A architecture. Unlike its 32-bit predecessors, ARM64 supports 64-bit virtual addressing and 64-bit data processing, enabling access to larger memory spaces and more complex computations. ARM64 processors execute instructions based on this ISA, which emphasizes simplicity and efficiency. Its RISC design means instructions are simpler and execute faster, often in a single clock cycle, leading to lower power consumption. It features a large register file and a load/store architecture, where data manipulation primarily happens in registers, reducing memory access overhead. ARM64 addresses the need for more powerful, yet energy-efficient computing across diverse platforms. It enables devices to handle more demanding applications, larger datasets, and more complex operating systems, while extending battery life in mobile devices and reducing operational costs in data centers. It is widely used by major tech companies like Apple (M-series chips), Qualcomm (Snapdragon), Samsung (Exynos), and Amazon (Graviton) for their respective products. Its applications span mobile computing, embedded systems, automotive, enterprise servers, and high-performance computing (HPC).
