Processor design

Even Qualcomm, those Snapdragon chips are based off of ARM architecture.

And it's really a more energy efficient CPU design.

And it's op- I won't say open source, but it's, it's licensed so that the ARM company, they develop the instructions that the CPU uses, but then these companies that design the actual chip have their own flavor of how they're using those ARM instructions.

And so they can design the chip to whatever the specific workload is that they're trying to optimize for.
