Apple's iPhone chip plans leaked on LinkedInA senior chip design manager from PA Semi, Wei-han Lien, let a little light shine on Apple's plans for future generations of the iPhone and iPod by listing "Manage ARM CPU architecture team for iPhone" as his current gig on LinkedIn (Lien's profile has since been scrubbed from the site). CEO Steve Jobs had already let it be known that new Apple subsidiary would be working on chips for the popular mobile devices, and now we know that they will be basing designs on the same ARM architecture that Samsung licensed for the current batch, though with Apple's own proprietary improvements. PA Semi was known for crafting highly efficient, low-power chips. Other features, such as graphics and video processing and multi-touch controls, can also be embedded directly in CPU. Tighter integration with the surrounding electronics in the entire chipset can also be achieved with a custom design. As for PA Semi's role in supplying defense contractors with the company's famously efficient designs, not to worry — a contractor says he'll be able to provision chips popular in military applications for "four to five years."
