'''Arm Holdings plc''' (stylised in lowercase as '''arm''', formerly an acronym for Advanced [[Reduced instruction set computer|RISC]] Machines and originally [[Company:Acorn Computers|Acorn RISC Machine]]) is a British [[Physics:Semiconductor|semiconductor]] and software design company based in Cambridge, England, whose primary business is the design of [[Central processing unit|central processing unit]] (CPU) cores that implement the [[ARM architecture family]] of instruction sets. It also designs other chips, provides software development tools under the DS-5, RealView and [[Company:Keil|Keil]] brands, and provides systems and platforms, system-on-a-chip (SoC) infrastructure and software. As a "holding" company, it also holds shares of other companies. Since 2016, it has been owned by Japanese conglomerate SoftBank Group.

While ARM CPUs first appeared in the [[Engineering:Acorn Archimedes|Acorn Archimedes]], a [[Engineering:Desktop computer|desktop computer]], today's systems include mostly [[Embedded system|embedded system]]s, including ARM CPUs used in virtually all modern [[Engineering:Smartphone|smartphone]]s. Processors based on designs licensed from Arm, or designed by licensees of one of the [[ARM architecture family|ARM instruction set architectures]], are used in all classes of computing devices. Arm has two lines of [[Graphics processing unit|graphics processing unit]]s (GPUs), [[Mali (processor)|Mali]], and the newer Immortalis (which includes hardware-based [[Ray tracing (graphics)|ray-tracing]]).<ref>{{Cite web |last=Schoon |first=Ben |date=28 June 2022 |title=Arm's new Immortalis GPU sets the stage for more Android phones with ray-tracing support |url=https://9to5google.com/2022/06/28/arm-immortalis-gpu-ray-tracing-android/ |access-date=7 July 2022 |website=9to5Google |language=en-US}}</ref>

Arm's main CPU competitors in servers include [[Company:IBM|IBM]], [[Company:Intel|Intel]] and [[Engineering:AMD|AMD]].<ref>{{cite web |url=https://www.eetimes.com/cavium-flexes-arm-server-upgrade/ |title=Cavium Flexes ARM Server Upgrade |first=Rick |last=Merritt}}</ref> Intel competed with ARM-based chips in mobile but Arm no longer has any competition in that space (however, vendors of actual ARM-based chips compete within that space). Arm's main GPU competitors include mobile GPUs from technology companies [[Company:Imagination Technologies|Imagination Technologies]] ([[PowerVR]]), [[Company:Qualcomm|Qualcomm]] ([[Adreno]]), and increasingly [[Company:Nvidia|Nvidia]], [[Engineering:AMD|AMD]], [[Company:Samsung|Samsung]] and Intel. While competing in GPUs, Qualcomm, Samsung and Nvidia all have combined their GPUs with Arm-licensed CPUs.

Arm had a primary listing on the [[Company:London Stock Exchange|London Stock Exchange]] (LSE) and was a constituent of the FTSE 100 Index. It also had a secondary listing of [[Finance:American depositary receipt|American depositary receipt]]s on New York's [[Finance:Nasdaq|Nasdaq]]. However Japanese multinational conglomerate SoftBank Group made an agreed offer for Arm on 18 July 2016, subject to approval by Arm's shareholders, valuing the company at £24.3 billion.<ref name=bbc18July>{{Cite news |date=18 July 2016 |title=ARM chip designer to be bought by Japan's Softbank |language=en-GB |work=BBC News |url=https://www.bbc.com/news/business-36822806 |access-date=7 July 2022}}</ref><ref>{{cite press release |title=SoftBank Offers to Acquire ARM Holdings for GBP 24.3 Billion (USD 31.4 Billion) in Cash |url=https://www.businesswire.com/news/home/20160717005081/en/SoftBank-Offers-to-Acquire-ARM-Holdings-for-GBP-24.3-Billion-USD-31.4-Billion-in-Cash |website={{wipe|Business Wire}} |date=18 July 2016 |access-date=14 September 2023}}</ref> The transaction was completed on 5 September 2016.<ref name=silicon>{{cite news|url=https://www.siliconrepublic.com/companies/softbank-arm-takeover-completed|title=SoftBank finally completes £24bn ARM takeover|publisher=Silicon Republic|date=5 December 2016|access-date=5 September 2016}}</ref><ref name="Acquisition of ARM Holdings plc. by SoftBank Group Corp.">{{cite web|url=https://silver.arm.com/news.tm?msgid=9011|title=Acquisition of ARM Holdings plc. by SoftBank Group Corp.|website=silver.arm.com}}</ref> A planned takeover deal by Nvidia, announced in 2020, collapsed in February 2022,<ref>{{Cite web |date=8 February 2022 |title=Nvidia's $40bn takeover of UK chip designer Arm collapses |url=https://www.theguardian.com/business/2022/feb/08/nvidia-takeover-arm-collapses-softbank |access-date=8 February 2022 |website=the Guardian |language=en}}</ref> with SoftBank subsequently deciding to pursue an initial public offering on the Nasdaq in 2023, valuing Arm at {{US$|54.5}}{{nbsp}}billion.<ref>{{cite web |title=Chip giant Arm raises nearly $5 billion in year's largest IPO |url=https://www.axios.com/2023/09/13/arm-ipo-pricing-nvidia-chips |website=Axios |access-date=14 September 2023}}</ref>

==History==

===Name===
The acronym ARM was first used in 1983 and originally stood for "Acorn RISC Machine". [[Company:Acorn Computers|Acorn Computers]]' first RISC processor was used in the original [[Engineering:Acorn Archimedes|Acorn Archimedes]] and was one of the first RISC processors used in small computers. However, when the company was incorporated in 1990, what 'ARM' stood for changed to "Advanced RISC Machines." According to [[Biography:Steve Furber|Steve Furber]] the name was changed at the behest of Apple, which did not wish to have the name of a competitor in the name of the company. At the time of the [[Finance:Initial public offering|IPO]] in 1998, the company name was changed to "ARM Holdings",<ref>{{Cite web |url=https://quotes.nasdaq.com/asp/SummaryQuote.asp?symbol=ARMH&selected=ARMH |title=Company Description (as filed with the SEC) |publisher=NASDAQ |access-date=18 April 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110505072606/http://quotes.nasdaq.com/asp/SummaryQuote.asp?symbol=ARMH&selected=ARMH |archive-date=5 May 2011 }}</ref> often just called ARM like the processors.<ref name=companieshouse>{{cite web|url=https://find-and-update.company-information.service.gov.uk/company/02557590|title=Arm Limited|publisher=Companies House|access-date=13 February 2022}}</ref>

On 1 August 2017, the styling and logo were changed. The logo is now all lowercase ('arm') and other uses of the name are in sentence case ('Arm').<ref name="companieshouse" /><ref>{{cite web |url=http://linuxgizmos.com/arm-becomes-arm-or-is-it-arm/ |title=Chip IP designer ARM becomes "Arm" — or is it arm? |date=7 August 2017 |author=Eric Brown |website=LinuxGizmos.com }}</ref>

===Founding===
The company was founded in November 1990 as '''Advanced RISC Machines Ltd''' and structured as a [[Finance:Joint venture|joint venture]] between [[Company:Acorn Computers|Acorn Computers]], [[Company:Apple Inc.|Apple]], and [[Company:VLSI Technology|VLSI Technology]]. Acorn provided 12 employees, VLSI provided tools, Apple provided a US$3&nbsp;million investment (equivalent to ${{Inflation|index=USD|value=3|start_year=1990}}&nbsp;million in {{Inflation/year|index=USD}}).<ref name="ARM-BriefHistory1">{{cite web |last1=Walshe |first1=Ben |title=A Brief History of Arm: Part 1 |url=https://community.arm.com/developer/ip-products/processors/b/processors-ip-blog/posts/a-brief-history-of-arm-part-1 |website=ARM |archive-url=https://web.archive.org/web/20210303023745/https://community.arm.com/developer/ip-products/processors/b/processors-ip-blog/posts/a-brief-history-of-arm-part-1 |archive-date=3 March 2021 |date=21 April 2015 |url-status=live}}</ref><ref name="LATimes-19901128">{{cite web |last1=Weber |first1=Jonathan |title=Apple to Join Acorn, VLSI in Chip-Making Venture |url=https://www.latimes.com/archives/la-xpm-1990-11-28-fi-4993-story.html |work={{wipe|Los Angeles Times}} |archive-url=https://web.archive.org/web/20210325060916/https://www.latimes.com/archives/la-xpm-1990-11-28-fi-4993-story.html |archive-date=25 March 2021 |date=28 November 1990 |url-status=dead}}</ref> [[Biography:Larry Tesler|Larry Tesler]], Apple VP was a key person and he helped recruit the first CEO at the joint venture, Robin Saxby.<ref>{{Cite web|last=Schofield|first=Jack|date=28 February 2020|title=Larry Tesler obituary|url=http://www.theguardian.com/technology/2020/feb/28/larry-tesler-obituary|access-date=30 June 2021|website=The Guardian|language=en}}</ref><ref>{{Cite web|date=19 February 2020|title=Larry Tesler, Legendary Apple Employee Behind Cut, Copy, And Paste Passes Away Aged 74|url=https://www.macobserver.com/news/larry-tesler-legendary-apple-employee-behind-cut-copy-and-paste-passes-away-aged-74/|access-date=30 June 2021|website=The Mac Observer|language=en-us}}</ref> The new company intended to further the development of the [[ARM architecture family|Acorn RISC Machine]] processor, which was originally used in the Acorn Archimedes and had been selected by Apple for its [[Software:Apple Newton|Newton]] project.

=== Dispute over Arm China leadership ===
SoftBank Group sold more than half of Arm China in 2018 to a local consortium consisting of various parties including China Investment Corp. and the Silk Road Fund, effectively relinquishing majority ownership of its Chinese subsidiary to a group of investors with ties to the Chinese state. From 2020, a discord between Arm and the effective owners of Arm China became visible after the British parent company unsuccessfully tried to oust the chief executive of the subsidiary, who, however, managed to retain his position.<ref>{{Cite news|title=Inside the battle for Arm China|work=FT|url=https://www.ft.com/content/dc55d4c9-1065-4db0-98a4-f7f0c1de563b}}</ref><ref>{{Cite web|title=How SoftBank's sale of Arm China sowed the seeds of discord|url=https://asia.nikkei.com/Business/China-tech/How-SoftBank-s-sale-of-Arm-China-sowed-the-seeds-of-discord|access-date=4 September 2021|website=Nikkei Asia|language=en-GB}}</ref> A prevailing view emerged that the matter would negatively affect the pending approval by the Chinese regulators of the Softbank-Nvidia deal, as well as any [[Finance:Public offering|public offering]] of Arm.<ref>{{Cite web|title=Battle at Arm China threatens $40bn Nvidia deal|url=https://asia.nikkei.com/Business/Technology/Battle-at-Arm-China-threatens-40bn-Nvidia-deal|access-date=11 June 2021|website=Nikkei Asia|language=en-GB|archive-date=11 June 2021|archive-url=https://web.archive.org/web/20210611050712/https://asia.nikkei.com/Business/Technology/Battle-at-Arm-China-threatens-40bn-Nvidia-deal|url-status=dead}}</ref><ref>{{Cite news |last1=Gross |first1=Anna |last2=Bradshaw |first2=Tim |last3=McMorrow |first3=Ryan |date=11 February 2022 |title=SoftBank's plans for Arm IPO hit by legal battle over renegade China unit |work=FT |url=https://www.ft.com/content/8494d5f3-4f3e-4a1d-878d-cabb82e37778 |access-date=29 March 2022}}</ref>

==Licensees==
Companies often license these designs from Arm to manufacture and integrate into their own [[System on a chip|''System on chip'']] (SoC) with other components such as [[Graphics processing unit|GPU]]s (sometimes Arm's Mali) or [[Modem|modem]]/[[Engineering:Baseband processor|radio basebands]] (for mobile phones). Arm offers multiple licensing programs for their cores.<ref>{{cite web|url=https://www.arm.com/why-arm/how-licensing-works|title=How Arm Licensing Works|website=Arm Holdings|access-date=29 August 2020}}</ref> Arm also offers Artisan POP IP, where Arm partners with [[Engineering:Semiconductor fabrication plant|foundries]] to provide physical implementation, which allows faster [[Social:Time to market|time to market]].<ref>{{cite web|url=https://www.anandtech.com/show/13052/arm-and-samsung-extend-artisan-pop-ip-collaboration-to-7lpp-and-5lpe-nodes  |title= Arm and Samsung extend Artisan POP IP collaboration to 7LPP and 5LPE nodes |publisher=Anand Tech|date=6 July 2018|access-date=13 February 2022}}</ref>

In February 2016, Arm announced the Built on Arm Cortex Technology licence often shortened to Built on Cortex (BoC) licence. This licence allows companies to partner with Arm and make modifications to Arm Cortex designs. These design modifications will not be shared with other companies. These semi-custom core designs also have brand freedom, for example Kryo 280.<ref name=":0">{{Cite web|url=https://www.anandtech.com/show/10366/arm-built-on-cortex-license|title=ARM Details Built on ARM Cortex Technology License|last=Frumusanu|first=Andrei|website=www.anandtech.com|access-date=26 May 2019}}</ref>

In addition to licences for their core designs and BoC licence, Arm offers an "architectural licence" for their [[Instruction set architecture|instruction set architecture]]s, allowing the licensees to design their own cores that implement one of those instruction sets. An Arm architectural licence is more costly than a regular Arm core licence.<ref name="anand7112-arch-lic3">{{cite web|url=https://www.anandtech.com/show/7112/the-arm-diaries-part-1-how-arms-business-model-works/3|title=The ARM Diaries, Part 1: How ARM's Business Model Works|first=Anand Lal|last=Shimpi|publisher=Anandtech|page=3|date=28 June 2013|access-date=21 September 2013}}</ref>

The ''[[Social:Financial Times|Financial Times]]'' reported in March 2023 that Arm had planned to charge the licensees royalties based on the value of the device, instead of the prior model based on the chip's value.<ref>{{cite news |last1=Gross |first1=Anna |last2=Ting-Fang |first2=Cheng |last3=Inagaki |first3=Kana |date=23 March 2023 |title=Arm seeks to raise prices ahead of hotly anticipated IPO |url=https://www.ft.com/content/25ea2570-264d-472d-8ef8-3a02003e87ab |newspaper=[[Social:Financial Times|Financial Times]] |archive-url=https://archive.today/20230323055002/https://www.ft.com/content/25ea2570-264d-472d-8ef8-3a02003e87ab |archive-date=23 March 2023 |url-status=live}}</ref>
