iPhone Specifications

Apple posts the specifications for all hardware, but does not identify a processor for the iPhone. Considering the iPhone runs some level of Mac OS, is there a processor on board and has anyone identified what the processor might be? We certainly know it is not an Intel CoreDuo2, but there has to be some sort of a processor.

Oh, and no problems with the iPhone. It is great.

Well, I should have Googled for the processor before posting. If the sites are all accurate, then we have:

* ARM1176JZF chip with TrustZone (enables trusted computing environment for media, apps, network, OS, etc. -- very bad for hackers)
* Can vary in clock speed up to 700MHz or more, depending on implementation (thanks, Nigma)
* ARM Intelligent Energy Manager (claimed to reduce power consumption 25-50% in portables)
* 16K / 16K cache
* Features vector floating point coprocessor ("for embedded 3D-graphics")
* ARM Jazelle enabled for embedded Java execution (hmm...)
* SIMD, high perf integer CPU (8-stage pipeline, 675 Dhrystone, 2.1 MIPS)
* 0.45 mW/MHz power draw (with cache)
