Yep, I know that.
How is it possible that apple can make their SoC's using other chips??
I seriously doubt ARM is just gonna give their schematic to apple and let apple find a 3rd party chip manufacturer to make it!
and what you're saying is that MULTIPLE companies are going to give their chip schematics to apple,
and let them combine the chips into a single die then manufacturer it?
There's NO WAY that's gonna happen.
There are in general two types of lisences for ARM, ones where you use their ARM v7 or ARMsomething 7 instruction set and another where you use their exact processors. Apple and Qualcomm have both lisences.
ARM DOES THAT! They lisence their chips! Seriously! Look it up :) Their whole thing is built on this, the important thing is that it's lisenced.
No way? As we can see, Audience, Cirrus Logic have custom chips on the A5 SoC as well as the TI chip, these schematics are not secret but they are lisenced. But yes, the SoC's for phones today use many CUSTOM parts or non custom parts from various manu's
