Three Even-Rate Tasks with Preemption and the Base-Rate
and Sub-Rate 1 Tasks Overrun
In this three-task scenario, two of the tasks overrun—the Base-Rate and
Sub-Rate 1.
• The overrunning B ase-Rate executes every 2ms.
• Sub-Rate 1 overruns due to the Base-Rate overrun, doubling the execution
rate.
• Also, Sub-Rate 1 is overrunning as well, doubling the execution rate again,
from the intended 2ms to 8ms.
• Sub-Rate 2 responds to the overrunning Base-Rate and Sub-Rate 1 tasks
by running every 16m s instead of every 4 ms.
