ARM Architecture, It’s Generations and Applications:

Introduction:

In our previous content, we have described the Embedded system which is an integrated system combined with hardware and software. The hardware is the embedded development board which can be divided into five modules which are processor, memory, input devices, output devices, and Bus controllers. Among them, the processor is the core component.

Here the ARM architecture we are describing is actually a Processor architecture. ARM (stylized in lower case as an arm, previously was an acronym for Advanced RISC Machines and originally Acorn RISC machine) is a family of reduced instruction set computing (RISC) architectures for computer processors, configured for various environments.

ARM Ltd. Develops the architecture and licenses it to other companies who design their own products that implement one of those architectures including system-on-chips (SoC) and system-on-modules (SoM) that incorporate different components such as memory, interfaces, and radios. It also designs cores that implement this instruction set and license these designs to a number of companies that incorporate that core designs into their own products.

ARM Ltd. (stylized as an arm) is a British semiconductor and software design company based in Cambridge, England. Its primary business is in the design of ARM processors (CPUs) although it also designs other chips and software development tools.

Generations of ARM Architecture:

There are several different generations of ARM. The original ARM 1 used as a 32-bit internal structure but had a 26-bit address space that limited it to 64MB of main memory.

This limitation was later finished in the ARMv3 series, which has a 32-bit address space and several additional generations up to ARMv7 remained 32-bit. Later in 2011, the ARMv8A architecture released and added support for 64-bit address space and 64-bit arithmetic with its new 32-bit fixed-length instruction set.

ARM Ltd. Has also released a series of additional instruction sets for different rules; the “Thumb” extension adds both 32-bit and 16-bit instructions for directly handling Java bytecodes, and more recently, JavaScript. More recent changes include the addition of simultaneous multithreading (SMT) for improved performance of fault tolerance.

Applications of ARM Architecture:

Due to their low costs, minimal power consumption, and lower heat generation than their competitors, ARM processors are desirable for light, portable, battery-powered devices including smartphones, laptops, and tablet computers, as well as other embedded systems.

However, ARM processors are also used for desktops and servers including the world’s fastest supercomputer. With over 180 billion ARM chips produced, as of 2021, ARM is the most widely used instruction set architecture (ISA), and the ISA produced in the largest quantity. Currently, the widely used Cortex cores, older “classic” cores, and specialized SecurCore cores variants are available for each of these to include or exclude optional capabilities.

Why choose ARM Architecture?

On the corporation website, ARM gives two reasons for choosing ARM architecture. One is that “the most successful Architecture for the digital world”. The ARM architecture is the keystone of the world’s largest compute ecosystem. It enables our partners to build their products in an efficient, affordable, and secure way. ARM’s proven track record of delivering world-class architecture designs is reflected in the success of this diverse and ever-evolving ecosystem.

ARM’s architecture specifications are licensed by partners, who create compliant silicon chips based on them. With more than 125 billion devices containing ARM-based chips, our architecture empowers innovation in multiple markets enabling partner innovation.

The other is that “the foundation for Possible”. ARM architecture specifies a set of rules that dictate how the hardware works when a particular instruction is executed. It is a contract between the hardware and the software, defining how they interact with one another.

When software is written to conform to ARM specifications, any ARM-based processor or chipset will execute it in the same way. This is the foundation of the portability and compatibility promise, underlying the ARMecosystem. Our architecture is consistent, compatible and it delivers.

ARMS system and security Architectures provide standardization and best practice guidance, enabling the ecosystem to reduce cost and accelerate time to market when designing systems.

Through sustained collaboration with our partners, our next generation of architecture will enable designs that push the boundaries of compute.
