The imprecise computation technique, which prevents timing faults and achieves graceful degradation by giving the user an approximate result of acceptable quality whenever the system cannot produce the exact result in time, is considered. Different approaches for scheduling imprecise computations in hard real-time environments are discussed. Workload models(More)
In multiprocessor and distributed real-time systems, scheduling jobs dynamically on processors is likely to achieve better performance. However, analytical and eecient validation methods to determine whether all the timing constraints are met do not exist for systems using modern dynamic scheduling strategies, and exhaustive simulation and testing are(More)
