Any company that makes Arm chips must license technology from Arm Holdings plc, the British company that develops the instruction set. Companies can license the instruction set and create their own CPU designs or license one of Arm's ready-made Cortex CPU core designs to incorporate into their own chips.

Arm has finally thrown its toys and given 60 days notice that it intends to cancel Qualcomm's licence to produce chips based on Arm technology. So says Bloomberg, which claims to have seen Arm documents detailing the move.

PCs with Intel and AMD processors also qualify as Copilot+ certified, so any failure to resolve the dispute, or defeat for Qualcomm, won’t disrupt AI capabilities from appearing in Windows laptops, but the Oryon core is also used in high-end smartphones and tablets due for release in the coming weeks.
