Testing of the Execution of the Task
In real-time system, to ensure the deadline of the task is met, it is absolutely necessary to measure the execution time of an individual task. This paper firstly describes two approaches to measure the execution of the task, and then compares and analyses their merits and demerits. What is more, some problems should be paid attention to under test. At last, the factors which impact the task's execution are discussed and a design proposal is presented which shows how to effectively test the execution of the task.
