The embedded control system through real-time task

This paper deals with the study of Embedded Control System through Real-Time Task. In the embedded control system, we decompose a component into several real-time tasks. To ensure safety control of tasks at run-time, we define service and reconfiguration processes for tasks and use the semaphore concept to obtain safety mutual exclusions. The Priority Ceiling Protocol (PCP) is applied as an approach to ensure the scheduling between periodic tasks with precedence and mutual exclusion constraints. We simulate the scheduling of Real-time tasks with PCP through the Cheddar tool.
