You have the reading comprehension of a third grader. The CPU is handled via hardware, the GPU is not, some other small pieces are handled via hardware because they're almost identical. If an integral part is missing from the Vita how do you believe it is solved in software?
Hint: The rest of the world calls the approach Sony picked emulation.
You are so precious! Comparing a complex part like a GPU running actual code to something like RAM whose only purpose is to hold and move data. What an amazing straw man, and then the rhetorical question to try and get a claim of authority, truly a work of art.
Please tell me which code is being run on a RAM chip, I am on the edge of my seat for your explanation.
That is indeed what is made possible with the general purpose emulator Sony offers on the Vita. If the Vita didn't offer emulating a PSP GPU as a baseline feature you would not be able to load up any PSP ISO files and play them without any extra steps on your part.
Now you just need to find someone with a few more crayons than I have and ask them to explain to you what "natively" means to the rest of the world outside your make believe playground, and then what "porting" means for good measure, and then you might have a chance understanding my point from over two days ago.
And potentially miss you throwing another tantrum? No, thank you.
