| 28 | System initialization file |
||
| 29 | |||
| 30 | The tick is set to TICK ms. |
||
| 31 | |||
| 32 | This file contains the 2 functions needed to initialize the system. |
||
| 33 | |||
| 34 | These functions register the following levels: |
||
| 35 | |||
| 36 | an EDF (Earliest Deadline First) level |
||
| 37 | a POSIX (32 levels RR/FIFO) level |
||
| 38 | a CBS (Costant Bandwidth Server) level |
||
| 39 | a Dummy level |
||
| 40 | |||
| 41 | It can accept these task models: |
||
| 42 | |||
| 43 | HARD_TASK_MODEL (wcet+mit) at level 0 |
||
| 44 | NRT_TASK_MODEL at level 1 |
||
| 45 | SOFT_TASK_MODEL (met, period) at level 2 |
