This document contains an overview of the Arm architecture and information on A32, T32, and A64 instruction sets. For assembler-specific features, such as additional pseudo-instructions, see the …

In ARM state, all instructions are conditionally executed according to the state of the CPSR condition codes and the instruction’s condition field. This field (bits 31:28) determines the circumstances under …

ARM (stylised in lowercase as arm) [a] is a family of RISC instruction set architectures for computer processors. Arm Holdings develops the instruction set architecture and licenses them to other …

Main features of the ARM Instruction Set All instructions are 32 bits long. Most instructions execute in a single cycle.

Mnemonic represents the operation to be performed. The number of operands varies, depending on each specific instruction. Some instructions have no operands at all. Typically, operand1 is the …

This site offers reference documentation for the AArch64 instruction set and system registers defined by the Armv8-A and Armv9-A architectures. You can use the search field below (and at the top of every …

A64 is the instruction set used in AArch64, supported by the Armv8-A, Armv8-R AArch64 and Armv9-A architectures.

Comprehensive reference guide for developers on Arm instruction sets, providing detailed documentation to aid in efficient programming.

This document provides a high-level overview of the ARMv8 instructions sets, being mainly the new A64 instruction set used in AArch64 state but also those new instructions added to the A32 and T32 …
