Introduction to the ARM Instruction Set

Introduction to the ARM Instruction Set

ARM is an instruction set architecture developed by ARM Holdings plc, a British multinational semiconductor and software design company. It is one of the most widely used architectures in the world today, powering billions of handheld and embedded devices, including smartphones and tablets.

An instruction set is a set of instructions that a computer processor understands. An instruction set is the basis for writing computer programs. The ARM instruction set is a reduced instruction set computing (RISC) architecture developed by ARM Ltd.

The ARM instruction set has been designed for simplicity and speed, offering efficient implementations for many common operations. For example, the ARM instruction set includes instructions for adding, subtracting, multiplying and dividing, as well as shifts, rotates, and barrel shifts. It also allows more complex operations, such as setting and clearing bits, bit shifting and masking, logic operations, and conditional branch instructions.

In addition to its simple, efficient instruction set, the ARM architecture offers a wide range of features such as vector processing and low power consumption. It also supports multiple processor cores and multiprocessing.

The ARM instruction set is one of the most pervasive instruction sets in the world, and it’s used in a variety of devices, from smartphones and tablets to embedded systems and robotics.
