Real-time task scheduling in embedded multiprocessor systems, as the name implies, is known as a problem because of two major difficulties: identifying tasks' priority and task assignment issue. The former, has especially a significant importance in the case of global real-time scheduling on symmetric multiprocessor environment. The great importance of priority assignment becomes even clearer when...
The design of real-time systems for safety-critical applications depends heavily on the normal operation of system, in critical conditions. In these applications, among of real-time tasks, a critical task must be immediately scheduled at its arrival time immediately; otherwise, it leads to a system failure and disasters in safety-critical applications. A major problem in real-time systems included...
Reconfigurable devices employed in safety-critical real-time applications ought to tolerate faults in a timely manner. Fault-tolerant schedulers can be used to guarantee both real-time and fault-tolerant behaviors of such systems. In this paper the effects of three real-time scheduling algorithms Earliest Deadline First (EDF), Least Laxity First (LLF), and Rate Monotonic (RM) enhanced by two fault...
