This program demonstrates using watchdog timers to invoke Deadline handlers. CoordinatorTask sends data to the organizer. OrganizerTask receives data from the coordinatorTask, and resets the coordinatorTask when no data is sent by the coordinatorTask in the past five seconds (Deadline time). This demonstration program is automatically stopped after twenty seconds.

In a preemptive priority based RTOS, priority inversion problem is among the major sources of Deadline violations. Priority inheritance protocol is one of the approaches to reduce priority inversion. Unfortunately, RTOS like uC/OS can’t support priority inheritance protocol since it does not allow kernel to have multiple tasks at the same priority. Although it has different ways to avoid priority inversion such as priority ceiling protocol, developers still have some difficulties in programming real time applications with it. In this paper, we redesign the uC/OS kernel to provide the ability to support round robin scheduling and implement priority inheritance semaphore on the modified kernel. As result, we port new kernel with priority inheritance semaphore to evaluation board, and evaluate the execution time of each of the kernel service as well as verify the operations of our implementation.
