Further to an “email to the editor” which estimated that there may be three ARM processor cores in the Apple iPhone, reports came forward that the main CPU for the iPhone is a PXA320, formerly the Monahan applications processor from Intel, now supplied by Marvell. “ARM is in 90 percent of the world’s [mobile phone] handsets; we’re in WiFi, baseband processors and applications processors and most of the world’s MP3 players. So it’s at least three,” East said.
