MIPS processors are emulated using either a simple binary translation |
16 |
|
layer (recompilation into native code), which is used on Alpha and i386 |
17 |
|
hosts, or by traditional interpretation (very very slow, but works on any |
18 |
|
host platform). |

|
ARM and PowerPC processors are emulated using a newer dynamic translation |
21 |
|
system. Performance is somewhere between traditional interpretation and |
22 |
|
recompilation into native code. However, the dynamic translation system |
23 |
|
used in GXemul does NOT generate native code, and thus doesn't require |
24 |
|
platform-specific back-ends. In plain English, this means that the |
25 |
|
dyntrans system works on any host platform. |

then I suggest you compile a Hello World program according to the tips |
