Apple's iPhone is powered by processors manufactured by ARM Holdings, ARM Holding's CEO has confirmed.

Warren East, ARM Holdings president and CEO has claimed that the iPhone carries "at least three" ARM-designed processor cores.

EE Times claims that these three processors might include (as main CPU) the "PXA320, formerly the Monahan applications processor from Intel Corp, now supplied by Marvell Technology Group".

East declined to offer more specific details, citing "client confidentiality".

"Apple will talk about the contents of the iPhone when Apple's ready to talk about the contents of the iPhone," he said.
