2 | =========== |

| - | 4 | mips32 is the second port of SPARTAN kernel originally written by Jakub Jermar. |
|
| - | 5 | It was first developed to run on MIPS R4000 32-bit simulator. |

6 | Now it can run on real hardware as well. |
| - | 7 | It can be compiled and run either as little- or big-endian. |
|

| 8 | Note that msim diverges from real MIPS hardware in some aspects. |
9 | HARDWARE REQUIREMENTS |
| 9 | Therefore, some non-trivial changes will be necessary for a real |

| 10 | hardware port. The simulator is described in this manual: |
11 | o emulated MIPS 4K CPU |

| - | 13 | COMPILER REQUIREMENTS |
|
| - | 14 | o mips binutils 2.16 and gcc 4.0.1 cross compiler |
|
| - | 15 | o older versions may do as well, but are now obsoleted |
