| 58 | -- |
---|
| 59 | -- This subprogram performs test initialization. As each application |

| 61 | -- perform a blocking MESSAGE_QUEUE_RECEIVE. Once all of the |
---|
| 62 | -- initialization is completed, the timer is started and the first |

---|
| 78 | -- task to be enqueued waiting for a message and the last task |
---|
| 79 | -- to receive the message. Once it receives the message, it |
---|
| 80 | -- stops the timer and reports the execution time for a |
