They found CPU, GPU and cache. What is in the remaining 40% of the chip? There are a lot of individual blocks in there.

- MCRed 12y agoThis is where Apple really adds value and why they have their own silicon design teams. Some of the blocks: -- M7 motion chip -- Image processing chip to support camera -- (I suspect) audio processing chip to do compression and feature extraction for SIRI -- (suspect) video codec (though this may be done by GPU) -- Secure Enclave -- CPU with secure data, random number generator, Apple Pay support, Fingerprint Sensor support -- (I suspect) memory management units and io co-processors and the like that are too mundane to get much public mention
- nilsimsa 12y agoThe motion chip is a separate package.
- joezydeco 12y agoChipworks decapped the M7 on the iphone5 and found it to be a custom model of the LPC18xx from NXP http://www.chipworks.com/en/technical-competitive-analysis/resources/blog/inside-the-iphone-5s/ http://www.chipworks.com/en/technical-competitive-analysis/r... http://www.nxp.com/products/microcontrollers/cortex_m3/lpc1800/ http://www.nxp.com/products/microcontrollers/cortex_m3/lpc18...
- makomk 12y agoHardware video codec support is almost always a seperate module, yeah, as are audio processing and video input/output.

- awalton 12y agoA big part of what Chipworks does (as a company) is reverse engineering silicon from die shots and x-rays and such. They're not just going to hand this kind of information out on a platter - they were commissioned to do a cursory glance for this puff piece. But it also doesn't take a genius to guess at what the various hardware modules do just given what the iPhone can do.
