Yes, AMD's PSP is actually licensed from ARM, its why there is a small ARM Cortex CPU on AMD's CPUs and APUs. The first few times they tried adding it on did not go well FYI, so they disabled this small chunk of silicon at the factory.

In 2013 AMD successfully fabricated a CPU with said ARM Cortex core embedded, thus that was the first year they actually offered their PSP. AMD had similar problems with their APU's for a number of years IIRC, whereby making a single chip with both CPU and GPU on it had poor yields with a high percentage of dead chips.

No, it is not licensed from Arm. AMD's PSP is a system built by AMD itself, it just happened for them to buy Arm cores to build their system.

They could have used MIPS, PowerPC or any other CPU cores for PSP, they just decided to go with Arm.

IIRC it also heavily depends on ARM's TrustZone architecture, it's not like they just "happened" to use ARM.

I mean, they did license it from ARM; it's a Cortex A5 last time I checked.
