Nearly 80 years after the first transistor, silicon chips are now central to the way the world works in the 21st century. ARM microprocessors are the most ubiquitous “brains” in the products which we take for granted. The worldwide semiconductor industry revenues last year totalled approximately 330 billion dollars. ARM chips accounted for almost a quarter of that… This interview with the recent ARM CEO, Warren East, will explore how ARM has achieved such a strong position in the microprocessor marketplace. Approximately 8 ARM microprocessors for each and every person on the planet have been shipped over the last decade and a half. ARM processors are a largely invisible but essential part of the lives of almost every one of us, and will play an increasing role in dealing with the big questions of population growth and efficient use of scarce natural resources. Why has the market evolved this way? What does ARM do to remain at the centre of the digital revolution? What does the interface of technology and business look like for ARM ? Warren will provide a brief overview of the microprocessor marketplace and how the semiconductor industry has evolved over the last few decades, together with a thumbnail sketch of ARM , its business and its market.
