UK-based chipmaker ARM had yet another profitable quarter, announcing that the end of 2012 saw pre-tax profits of around $126 million -- an increase of 16 percent since the same period last year. Revenue totaled $262.8 million for Q4 and with a huge proportion of Android and iOS devices containing chip know-how from ARM, it continues to benefit from the smartphone boom. In fact, shipments of chips based on its processors totaled 2.5 billion in Q4 alone, while royalty revenue grew 21 percent year-on-year, thanks to successes with both its Cortex-A and Mali silicon series. ARM chief exec Warren East added that the company is "well positioned" to have a great 2013, too -- unless everyone stops buying phones all of a sudden.
