Design of Heterogeneous Multiprocessor Systems for Real-Time Applications
Project Description
The worst-case execution time model, though it guarantees all deadlines, if feasible,
leads to significant under-utilisation of the hardware platform and implicitly to expensive
products. Therefore, where applicable (soft real-time systems),
a model based on stochastic task execution times is better suited for the design.
The application is modelled as a set of task graphs. The tasks are periodic and statically mapped. The task deadlines are shorter than or equal to the task period. The probability distribution functions of the task execution times are arbitrary and given. The scheduling policies are given and arbitrary.
