| 24 | ------------ |
||
| 25 | |||
| 26 | Performance test 1: |
||
| 27 | |||
| 28 | there is one RR task that is preempted N_EDF times by an EDF task. |
||
| 29 | |||
| 30 | the test prints the differences of the execution time. |
||
| 31 | |||
| 32 | the test have to be compiled with the one shot timer, and it does not |
||
| 33 | use any init file. |
