81 | -- |
---|
82 | -- This RTEMS task is highest priority task in the system. |
---|
83 | -- Its first action is to perform a blocking EVENT_RECEIVE. |
---|
84 | -- It is the last task to have its event set sent to it. Thus it |
---|
85 | -- is the last task to be awakened by a preemptive EVENT_SEND. |
---|
86 | -- After it preempts the last MIDDLE_TASKS, it stops the timer |
---|
87 | -- and reports the execution time of preemptive EVENT_SEND. |

98 | -- |
---|

---|
100 | -- readied, each task will increment the TASK_COUNT and |
---|
101 | -- perform a preemptive EVENT_SEND. TASK_COUNT is used to |
---|
102 | -- index the TASK_ID array in such a way that incrementing |
---|
103 | -- TASK_COUNT makes it index the ID of the next task to |
---|
104 | -- send events to. |
