I find out that my pcsx_rearmed only use 1 arm core while my CPU has 4 arm cores. So, I presume that pcsx_rearmed use 1 GPU core while my CPU has 2 GPU cores also. Since I’m going to do a lot of job on it, is there any document about pcsx_rearmed and libretro I can read ?
Yes, the vast majority of emulators are fully single-threaded and are not easily/accurately parallelizeable. Sometimes vectorization/SIMD-ification can help speed up certain things, such as PCSX-ReARMed’s 32-bit NEON renderer.
PCSX-ReARMed is software-rendered, so it doesn’t use the GPU at all on its own. If you apply any shaders, etc., they will utilize the GPU however your driver decides to allow.

thanks,
It works quite well when I increase frequency of my CPU from 805MHz to 1GHz, and also optimize compile parameter from -O3 to -Ofast
