PA Semi team creating new ARM-based iPhone CPU

Apple Senior Manager Wei-han Lien let slip that teams acquired with the purchase of PA Semi are working on an ARM-based processor for the iPhone, and possibly other devices, according to The New York Times.

While not a huge surprise, as Steve himself said that's what the former PA Semi staff was working on, the question was still "what kind of processor?"

ARM variants can be customized to meet the needs of very specific devices, including supporting the multi-touch screen, or QuickTime playback. Electronista suggests that this supports earlier hints that Apple licensed the architecture from ARM under a secretive arrangement in late June.

Lien updated a section of his LinkedIn profile to describe what he was working on. (The NYT has a screenshot.) Oops. The profile, as you might expect, has been changed.
