There was a time when ARM processors were strictly for small devices such as mobile phones and embedded applications. But now the British processor maker has bigger ambitions: the data centre. ARM’s early successes were in the mobile phone arena as its processors were small and used very little power. But in terms of processing ability, ARM processors were not particularly powerful, and so weren’t suited to much more than basic smartphones.
Much has changed since then and today ARM processors are everywhere, from smartphones, to tablet PCs, to laptops.
Their compact size has made them popular for mobile applications but it’s their power efficiency that’s likely to lead to a boom in ARM’s market share over the coming years. Already many data centre operators are looking at ARM-based systems to provide the processing power they need while keeping the power consumption down.
