Understanding the Evolution of ARM (Advanced RISC Machine) so far


ARM processors have evolved over several decades, and you can broadly classify them both by their architectural versions (like ARMv4 through ARMv8 and beyond) and by their target families (such as Cortex‑A, Cortex‑R, and Cortex‑M). Each generation and family brings changes to both the register set and the instruction set. Here’s a breakdown: — 1….
