-- iPhone processor found: 620MHz ARM CPU
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)
- 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)
Update: Sascha at Gear Log seems to think given the recently discovered Samsung chip in the iPhone, perhaps the processor in question is a Samsung S3C6400, a recently-produced 667MHz ARM1176JZF-based CPU that seems to fit the bill.
via, with many thanks!
