Looks like today's morning's firmware leak turned up some well hidden details about the iPhone's hardware engine -- and also confirming some reports we'd previously received. From what we can tell, it looks like the iPhone's got a 620MHz ARM chip running under the hood. Specifics:
- ARM1176JZF chip with TrustZone (enables trusted computing environment for media, apps, network, OS, etc. -- very bad for hackers)
- Comes in 620 and 320MHz varieties -- no way the iPhone would be on 320MHz
- 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)
