MIPS processors are emulated using either a simple binary translation |
| 16 |
|
layer ("recompilation"), which is used on Alpha and i386 hosts, or by |
| 17 |
|
traditional interpretation (very very slow, but works on any host platform). |

ARM and PowerPC processors are emulated using a newer dynamic translation |

|
system. Performance is somewhere between traditional interpretation and |
| 21 |
|
dynamic recompilation; however, the dynamic translation system used in |
| 22 |
|
GXemul does NOT require platform-specific back-end code. In plain English, |
| 23 |
|
this means that the dyntrans system works on any host platform. |

(PowerPC emulation is still relatively new in 0.3.7, so dont't expect too |
| 26 |
|
much from it.) |
