26 | ------------ |
||
27 | |||
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 RR (Round Robin) 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 |
||
46 | |||
47 | This file is similar to the configuration of Hartik 3.3.1 |
||
