question about Neon SIMD support(android)

[[Unknown]]

Currently we don't make enough use of NEON. But the plan is to use it to improve texture loading, audio, and SIMD operations the PSP's CPU supports itself.

There's still a lot to optimize and improve even ignoring NEON, so I can say I'm sure it'll be faster even on non-NEON devices. But there are going to be some games that use SIMD heavily that will probably need NEON to get reasonable performance - that said, I'm just guessing.

Can't know the performance exactly until we write it. I'd expect the A9 to still do better as a guess.

I think 512 MB will be fine.

The PSP itself is NOT multicore. Videos and audio decoding (neither of which PPSSPP does yet) are done on a separate chip, and the GPU processing is done on a separate chip. We can move all of those off the main core, which definitely will help performance. What we can't do is make the game itself multicore - it will definitely break if we do, since PSP games were not written for multicore, and will get confused and trip.

So, in other words, I don't think PPSSPP will ever be able to utilize 4 cores. Probably at best 2 with some small stuff running on a third.
