This book is about the company culture that helped drive Arm Limited's spectacular growth to become the world's leading semiconductor Intellectual Property (IP) company. Its extremely power-efficient processor technology has been licensed to hundreds of semiconductor chip manufacturers and Original Equipment Manufacturers (OEMs). Arm is still largely unknown to the broader public, yet Arm's technology is nearly ubiquitous and has been a foundational building block of the global rise of the smartphone. Arm-based microprocessors power over 95% of the world's mobile phones. However, this book is not about technology. It's about how a company grew from being a small start-up in Cambridge, UK with 12 people and a GBP1.75m cash investment to a global organization with over 5,000 employees in over 50 countries and more than $1.5bn revenue in 2016 when SoftBank acquired it for $32bn. Arm Limited was founded as Advanced RISC Machines in November 1990, a joint venture between a British computer manufacturer, Acorn Computers Limited and its much larger US competitor, Apple Computers Inc. The purpose of the new venture was to develop and proliferate the uniquely power-efficient and high-performance RISC-based microprocessor technology that had been developed several years earlier by Acorn. Using first-hand interviews with founders and the author's knowledge, this book charts some of the key people involved in the birth of the technology and the company Advanced RISC Machines. It considers how their behaviors and decisions led to the creation of the licensing business model and the strategy that underpinned Arm's later success. This book reveals some of the layers that help explain how the combination of culture, strategy and execution built the world's leading semiconductor IP company. It provides insight into ten essential ingredients of Arm's success, including the company's unique proposition, how the early business model and strategy were formed, the creation and evolution of the winning culture, the ecosystem of shared success and how Arm stayed unified throughout a period of extraordinary growth. The purpose of the book is to help readers create a culture of inclusiveness, collaboration and innovation within their own organizations. The book provides examples from Arm's history which should provide inspiration and guidance for making the necessary changes to enable a winning culture. Additional details of interest to history lovers include the stories behind the BBC Microcomputer prototype, the Acorn RISC Machine microprocessor development, Advanced RISC Machines' creation, the partnership-focused licensing business model's development, the nearly lost design-win at Nokia for their new GSM mobile, the 20+ billion selling Cortex (R)-M product that almost didn't happen and the battle for smartphones and tablets with Intel. www.culturewon.com

Mit der programmgesteuerten Rechenanlage (Ziffern-Rechenautomat) ist vor etwa zwanzig Jahren ein Maschinentyp auf den Plan getreten, der Leistungen zu voll bringen imstande ist, die bis dahin der menschlichen Geistestatigkeit vorbehalten waren. Zu der Kraft-Maschine, welche menschliche Muskelkraft ersetzt, kam die Informations-Maschine *) hinzu, welche logisch erfaBbare Tatigkeiten der mensch lichen Ratio ausfiihren und somit den Menschen auf einer hoheren, der geistigen, Ebene entlasten kann. 1m Zuge der Entwicklung hat sich die programmgesteuerte Rechenanlage, der Prototyp der InformationsmaschiI'l'2, ein viel groBeres Anwendungsfeld erschlossen, als es durch die Interessen der Mathematiker gekennzeichnet ist. Andere Maschinentypen sind hinzugekommen, auf welche die Bezeichnung Rechen Automat nurmehr bedingt paBt, die aber andererseits Anspruch haben, ebenbiirtig an deren Seite gestellt zu werden. Dabei denkt man zum Beispiel an die tech nischen Modelle zur Beschreibung von Lernvorgangen, an Spezialzweckanlagen zur Datenverarbeitung, Spracheniibersetzung, logischen Beweisfiihrung, zur Aus fiihrung von Strategiespielen usw. In Anbetracht der Vielfalt der Interessen er scheint es nicht unbillig zu fragen, wo, an welcher Stelle im Gebaude der Natur und technischen Wissenschaften wir uns iiberhaupt befinden, ob eine einfache Interpretation des Sachverhalts iiberhaupt moglich ist, die uns ein Zurechtfinden erlaubt."

The Igth century was distinguished by the construction of machines with enormous power. During the last decade rapid progress has been made in the development of a completely different type of machine. These new machines, the electronic computers, are not built to generate power or to do mechanical work, but to perform logical operations and ca1culations. This new concept will have a profound influence on engineering, science, ami economy. In fact, the first effects of this development are already taking shape today. It is the purpose 01 this book to give a survey of the basic principles and applications of computers for the benefit of those who hitherto did not work with them, but who might have use for them in the future. The rapid progress of the engineering science has, naturally, led to a situation in which the practicing scientist and engineer cannot keep abreast of the progress in neighboring fields. The chapters of this book were prepared by distinguished experts in the field of computers for the non-expert who does not intend to become an expert, but W}: l0 wants Jo acquire a general understanding of the problems and solutions which he needs to effectively perform the work in his proper field. We address this book to the engineers and scientists who want to know the performance of computers, as weH as to the managers who are rnainly concerned with their econornic aspect.
