Warren East, president and CEO of ARM Holdings plc, confirmed that "at least three" processor cores developed at his company are present within the iPhone from Apple Inc.

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 Corp., now supplied by Marvell Technology Group Ltd. The PXA320 is therefore a descendant of the StrongARM processor developed by Digital Equipment Corp. under an architectural license from ARM in the 1990s.

When asked how many ARM processor cores were in the iPhone, East said his company has a good track record of not talking about customers' products. "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.

When asked to say if three was an underestimate or even a large underestimate, East said "Apple will talk about the contents of the iPhone when Apple's ready to talk about the contents of the iPhone."
