Companies can also obtain an ARM architectural licence for designing their own CPU cores using the ARM instruction sets. These cores must comply fully with the ARM architecture. Companies that have designed cores that implement an ARM architecture include Apple, AppliedMicro (now: Ampere Computing), Broadcom, Cavium (now: Marvell), Digital Equipment Corporation, Intel, Nvidia, Qualcomm, Samsung Electronics, Fujitsu, and NUVIA Inc. (acquired by Qualcomm in 2021).
Qualcomm has an architectural license and used to design their own ARM core in the Snapdragon 800, 805, 820 series. The 810 and later chips use licensed ARM cores. Then Q acquired Nuvia so they are designing their own custom cores again.
