| 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 a set of scheduling modules, in a fixed or |

| 35 | dynamic priority way... |
||
| 36 | |||
| 37 | It can accept these task models: |
||
| 38 | |||
| 39 | HARD_TASK_MODEL (wcet+mit) at level 0 |
||
| 40 | SOFT_TASK_MODEL (periodicity=APERIODIC) at level 1 |
||
| 41 | NRT_TASK_MODEL at level 2 |
||
| 42 | SOFT_TASK_MODEL (periodicity=APERIODIC, wcet (only if TBS) ) at level 3,4 |
