So what is going to happen with the Hisilicon[1] chips? Do they still get to keep using all the licenses they already agreed to? What will they do when they next cortex implementation comes out? Copy it?

- sanxiyn 7y agoHiSilicon already developed their own ARM64 core (not Cortex) in Kunpeng 920, although it is a server chip and not a mobile chip. I think HiSilicon is entirely capable of developing (not copying) their own core.
- 0xcde4c3db 7y agoThe thing about ARM is that they more or less act like they own the ISA itself, and have a huge patent portfolio. There's an expectation that a company have an "architecture license" to make their own ARM-compatible core from scratch (unless it's an obsolete version of the ISA, e.g. Amber [1]). So while you're right that Cortex per se isn't relevant, there's still a question of whether HiSilicon will legally be able to sell any new ARM-compatible core they design.
