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 CBSHD (Constant Bandwidth Server with Hard Deadlines) level |
||
39 | a Dummy level |
||
40 | |||
41 | |||
42 | |||
43 | |||
44 | It can accept these task models (into () the mandatory fields): |
||
45 | |||
46 | HARD_TASK_MODEL (wcet+mit) at level 0 |
||
47 | NRT_TASK_MODEL at level 1 |
||
48 | ELASTIC_HARD_TASK_MODEL (cnormal,period,wcet,maxperiod) at level 5 |
