Arm chips power the vast majority of the world's smartphones, as Arm licenses its designs to customers who can choose to bring the Arm cores to market or take an architectural license and design compatible but otherwise brand new designs of their own making. That's the approach Apple and Qualcomm have taken — who, in addition to designing smartphones, have brought Arm into the Mac OS space as well as Windows on Arm PCs. Though Qualcomm and Arm have had their legal differences over licensing Arm's cores — which have since been settled — an Arm representative declined to comment when asked if any ongoing legal issues would prevent Qualcomm from taking a license.
