 |
|
Out of sheer curiosity, is there SIMD on the PSP? (for example, using gcc intrinsics)
Do I need to set any compiler flags to take advantage of them?
Thanks |

| VFPU is a 32-bit float-point coprocessor using SIMD. But psp-gcc doesn't know about it and so doesn't have intrinsics for VFPU, only psp-as. Allegrex and standard FPU have no SIMD operation. |

Ah, I see. Thanks
I guess that means no SIMD for me if I don't want to go into ASM. |
