• Sub-Rate 1.Thefirst subrate task. Sub-Rate 1 task runs more slowly than
the Base-Rate task. Sub-Rate 1 task rate is 2ms in the exam ples so that
the task should execute every 2ms.
• Sub-Rate 2. In examples with three tasks, the second subrate task is
called Sub-Rate 2. Sub-Rate 2 tasks run more slowly than Sub-Rate 1. In
the examples, Sub-Rate 2 runs at either 4ms or 3ms.
- When Sub-Rate 2 is 4ms, the example is called even.
- When Sub-Rate 2 is 3ms, the example is called odd.
Note The o dd or even naming only identifies Sub-Rate 2 as being 3 or 4ms.
It does not affect or predict the performance of the tasks.
The following legend applies to the plots in the next sections:
• Blue triangles (
) indicate when the task started.
• Dark red areas (
) indicate the period during which a task is running
• Pink areas (
