What is ARM architecture?

ARM architecture refers to the architecture of a set of instructions (ISA) that semiconductor manufacturer based in the UK Holdings, PLC. is developing. This technology is best known for its application on processors or central processing units (CPU), low energy consumption or high energy efficiency. It is also designed with the concept of reduced computer technology (RISC), which means that it seeks to optimize the processor performance by simplifying the instructions for faster implementation. CPU -based ARMs mainly rely on the implementation of one cycle.

English computer company Acorn Computer was created by ARM architecture in October 1983 when it launched the ACorn RISC Machine Project project to come up with a more advanced processor for its personal computers focused on business (PC). This is mainly because the MOS Technology 6502, an 8 -bit processor popular for its relatively low costs, was too weak to handle some computer functions such as graphics -based user interfaces.

The Acorn Archimedes, released in 1987, was the first computer to contain an arm -based CPU. The second iteration, ARM2, is remarkable for overcoming Intel 80286 or IAPX 286. It was a processor by colleague Semiconductor Company Intel Corp. and used on an IBM personal computer on (IBM PC/AT) from international business machines. The success of the arms -based processors led to the morphination of society to the Advanced RISC Machines Ltd. In 1990, then by 1998 ARM Holdings.

Architecture

ARM includes an orthogonal instruction set. Although the Orthogonal term is used for something composed of the right angles, it is used in computer terminology to indicate a data object - in this case ISA - which works without affecting others or is statistically independent. ARM architecture uses 32 bits, which is the maximum size of the data it holds. More specifically, each processsor using the instrumentThe core sets have 16 32 -bit registers, which are small storage units that provide high -speed data access instead of the CPU to get it from anywhere else at slower speed.

Ironically, Arm architecture was originally designed for PC. Instead, the X86 instructional set, which monitors its origin at 8086 Intel or IAPX86, dominated the market at the end of the 90s. Compatible compatible computers with IBM PC and Macintosh computers from Apple have X86 processors from companies such as Intel and Advanced Micro Devices (AMD).

Meanwhile, Arm has moved to smaller electronic devices that are ideal for simplified technology and low energy consumption. By 2009, more than 90 percent of all mobile phones contained ARM processor. Other devices that use ARM architecture for their processors include personal digital assistants (PDA), portable multimedia players and calculators.
