64-bit ARM architecture, also known as AArch64.

The AArch64 ISA was introduced in ARMv8 processors. It features a whole new instruction set, register set, and requires different development tools to the 32-bit ARM ISA.

ARMv8 processors are also capable of running AArch32 instructions (as the old 32-bit ISA is retroactively called), in both ARM and Thumb modes.

  • ARM a64 instruction set architecture contains very detailed descriptions of each instruction available on this architecture, including encoding, pseudocode and behavior to the architectural state. This includes basic, SIMD and Floating-point instructions. Also contains common aliases.
