IPhone processor mystery revealed

During the six months that have passed since the official presentation of the iPhone, not so much was known about the long-awaited Apple phone. The lowest bow for it is worth giving, first of all, to the valiant representatives of the company, who have a unique skill to lose the gift of speech in response to questions about the detailed technical characteristics of the "iPhone" in general and about the processor in particular. However, what the creators of the phone refused to talk about, the device itself told me without further persuasion. Rather, its firmware, successfully managed to flow straight into the network just a few days.




Judging by the persons responsible for deciphering the code, the iPhone is equipped with an ARM1176JZF processor - a fairly powerful but economical “pebble” based on the ARM architecture and nominally giving out 620 megahertz even more). The chip is equipped with a relatively small amount of cache memory (16 KB / 16 KB), but it has Java support and a separate processor for processing three-dimensional graphics. All for the benefit of users. On the other hand, engineers didn’t deprive of attention and hackers: especially for them, the ARM1176JZF has a content protection technology TrustZone, which promises to lovers of hacking long hours of pleasant pastime.

Thus, the iPhone can be called one of the most powerful phones of modern times. One thing is bad: with the intelligent use of this power in the brainchild of Apple, so far, alas, it does not matter.
