What processor will the iPhone utilization ? That ’s one of the great unanswered question left in the backwash of Apple ’s launching of the iPhone this hebdomad , but a caper advertizement onApple ’s Web sitemay hint at the solution .

The open position is a networking engineer to work on the iPhone and as the advertizement makes clear , Apple is looking for someone who knows the Mac OS and embed platforms , and Arm central processing unit in particular .

An branch chip shot would be the coherent ingredient for a gimmick like the iPhone . Arm is already the dominant supplier of smartphone lotion processors , because its chips are knock-down enough to forgather the computing need of these products while at the same time requiring small power — a critical component to keeping the phones run for between charge .

If the iPhone ’s brain is Arm - based , it will represent a new guidance for Apple ’s Mac OS ten operating system , which will power the gadget .

To date Mac OS has been port to Intel ’s x86 processors and IBM ’s PowerPC , but Arm would comprise a third weapons platform for Apple ’s operate on system .

On the other hand , it is potential that Intel or IBM could modernize new processors that would encounter the iPhone ’s requirement , saving Apple from doing the porting work to make Mac o run on the new political program , said Peter Glaskowsky , expert analyst with the Envisioneering Group .

“ To me the telephone number one unresolved question about the iPhone is does it use an Arm with a port wine , or does it use some new PowerPC or x86 chip , ” he say .

Glaskowsky said that even if Apple is looking for Arm skill , that does n’t necessarily mean that Arm will be powering the iPhone ’s operating system . “ I would n’t read too much into that , ” he say of the advert . “ If you conceive about most forward-looking smart phone … it ’s very common for them to have four processors in the twist . ”

Apple could be using an Arm crisp to do something like voice compressing or to simply process wireless networking signals ( Apple ’s adis for a “ Bluetooth / WiFi ” software applied scientist ) .

“ It may have nothing to do with what ’s scarper Mac OS on there , ” Glaskowsky say .
