The ARM architecture refers to a family of RISC (Reduced Instruction Set Computing) based processor designs developed by ARM Holdings. Due to its high performance, low power consumption and scalability , it is widely used in various applications including mobile devices, embedded systems and IoT (Internet of Things) devices.
The main features of the ARM architecture are:
- RISC design : ARM processors use a simplified instruction set, resulting in faster execution and lower power consumption.
- Load-store architecture : Operations are performed only on data stored in registers, thus improving efficiency.
- Thumb instruction set : A compact 16-bit instruction set that reduces code size and improves performance in memory-constrained environments.
