The processor company that rarely sells processors: how Arm conquered mobile through licensing

Arm became one of computing’s most influential architecture companies without following the normal semiconductor-company model.

It generally does not manufacture the processors found inside phones, routers or servers. Instead, it licenses processor architecture and intellectual property to companies that build their own chips.

The roots of that model stretch back to Acorn Computers in Cambridge.

The first Arm chip existed before Arm the company

Acorn Computers was developing machines for the British personal-computer market during the early 1980s.

Sophie Wilson and Steve Furber led work on a new reduced-instruction-set processor that could deliver strong performance without enormous complexity or power consumption.

The first ARM1 silicon arrived in 1985.

RISC gave Acorn a different path

Reduced Instruction Set Computing simplified the processor’s instruction set so the hardware could execute operations efficiently.

The ARM2 later powered the Acorn Archimedes, one of the earliest consumer computers built around a RISC processor.

The architecture’s efficiency would prove especially valuable in devices where power and heat matter more than absolute desktop performance.

Apple helped turn an internal processor into an independent company

Advanced RISC Machines Ltd was formed in November 1990 as a joint venture involving Acorn Computers, Apple Computer and VLSI Technology.

The new company separated processor development from Acorn’s computer business and allowed the architecture to serve a wider market.

Apple’s Newton became one of the early products using Arm technology.

Licensing was the business model that changed everything

Arm did not need to build fabrication plants or sell every chip itself.

It licensed processor cores and architecture to semiconductor companies, which integrated Arm technology into their own system-on-chip designs.

This model allowed one instruction-set ecosystem to spread across products made by many competing chip vendors.

Mobile phones were the perfect market for low-power processors

Battery life placed strict limits on early mobile devices.

Arm’s power-efficient designs gained traction in phones during the 1990s and became increasingly important as feature phones evolved into smartphones.

Once developers, operating systems and semiconductor suppliers invested in the architecture, the ecosystem reinforced itself.

The smartphone boom made Arm almost invisible and almost everywhere

Modern smartphones generally contain multiple Arm-based processors, from application CPUs to controllers embedded in other components.

The company’s brand may not appear on the outside of a device, but its instruction set and IP became foundational to mobile computing.

SoftBank took Arm private in 2016

Arm had been publicly traded in London and on Nasdaq from 1998.

Japan’s SoftBank Group acquired the company in 2016, taking it private.

The transaction reflected expectations that Arm technology would expand far beyond smartphones into connected devices, vehicles and data centres.

The Nvidia deal failed, then Arm returned to the market

SoftBank agreed to sell Arm to Nvidia in 2020, but the proposed transaction faced major regulatory opposition and was abandoned in 2022.

Arm then returned to the public market through a Nasdaq initial public offering in September 2023, with SoftBank retaining control.

Servers and PCs broadened the architecture beyond phones

Arm-based processors increasingly moved into laptops, cloud servers and high-performance infrastructure.

The same energy-efficiency principle that made Arm attractive in mobile devices can also reduce power consumption in large data centres.

Arm now develops increasingly complete compute subsystems alongside individual CPU and GPU IP.

A company whose product is the blueprint

Arm’s history is important because it shows that semiconductor influence does not require owning fabs or selling branded chips.

The company created value by licensing an architecture that thousands of hardware designs could share.
