Multi-core for Fs-UAE
Hi !
Sorry I'm new here, maybe it's already done but ! M'm trying to have a better emulation of Amiga with fs-Uae On my odroid-u3+ With some options is better but not perfect (for speed) the odroid U3 have 4 core of 1.7Ghz, I'm not sure fs-uae use all this core in emulation, i'm correct ? If yes, it existe a compilation option for use multi-core ? thks a lot |

FS-UAE already utilizes multiple threads (for some tasks). The emulation itself have to run in a single thread since Amiga emulation is heavily synchronization-depended (different subsystems have to be emulated in a lock-step fashion).
While 4x 1.7 GHz sounds good on papir, the ODROID uses an ARM "embedded" CPU, and this is simply less powerful than current desktop and laptop CPUs. FS-UAE does not really target embedded devices (mobiles, etc). One issue is that the emulation is really quite demanding (another slightly less important issue is that FS-UAE isn't optimized for non-discrete GPUs). Here are some tips to get increased performance: http://fs-uae.net/performance. |

Off course ARM is not the same with Intel or Amd.
maybe in the futur, a omptimze version for arm, who know, we will see Yes, I already read and doing some modifications for performance, it's better. thks a lot. See You |

As far as I know the U3 renders OpenGL in software mode without hw-acceleration like most (all?) of those tiny ARM based devices. That's why it runs very slow.
You can give the unofficial GLES port a try, it should run faster: https://github.com/cnvogelg/fs-uae-gles My dualcore Cortex A7 can do basic A500 emulation (with some slowdowns). You could try to compile UAE4ALL2: http://eab.abime.net/showthread.php?t=73953 Good luck with that, I wasn't successful... |

I recall there was talk about emulating CPU with one core and chipset with another core back in the days on UAE, I got the impression that this was what --enable-penguins compile option did?
