In a real-time system, tasks must be completed before a deadline date. For the schedule, it is necessary to know their worst case execution time. These systems become more complex, they require an increasing power. To meet this demand, we can use processors that operate in addition to instruction-level parallelism, task-level parallelism. Thus, they are capable of performing several tasks in parallel. But the complexity of these processors impact the tightness of the worst case execution time. CarCore is a processor designed by the team of Professor Ungerer, University of Augsburg (Germany). It allows the simultaneous execution of multiple tasks within a single core. It was designed to temporally isolate a task of the influence of other tas...
