It's not correct to say they just license the insn set. They license ready to use cpu and gpu core designs (like the Cortex family in most Android phones).

- yosefk 5y agoIt depends on the customer. Apple and Nvidia indeed license just the ISA and build their own CPU implementation from scratch. At the other extreme, you can make a complete chip just from ARM IP - they have way more than CPU and GPU IP, they can sell you pretty much everything else, too. At the middle are chip makers taking eg ARM CPU IP but no other ARM IP and making other IP themselves or licensing from other vendors.
