Andriod - only 1 core ?

[ppssp213]

Is it possible to start an run ppsspp on a unused core seperate to the android OS? would there even be any benefit doing so? less bottlenecking?,
maybe have audio and input running on separate cores too.

eg: Quad core setup
1: Android OS, Background Apps
2: PPSSPP, Background Apps
3: PPSSPP - Input, I've never seen any background running apps use the 3rd core only the 1 & 2nd core, maybe apps jump to the next core depending on the amount of apps you have running idk i'm not that familiar with android, I always kill them with a task manager before gaming anyway.
4: PPSSPP - Audio

also are geometry calculations done by cpu then passed onto the gpu to process before outputting to the screen or is it all soley done by the gpu?
