Workshop on Operating Systems Platforms for Embedded Real-Time applications (OSPERT 2007)
Pisa, Italy, July 3, 2007


Summary

The aim of this work is to complement the previous work on scheduling soft tasks in hard real-time systems based on fixed-priority preemptive scheduling. This work will provide an experimental view of the most representative policies in the literature, measuring both their performances and overheads. The performance of aperiodic scheduling policies has been traditionally evaluated by means of simulations that compute the average response times of soft tasks. In our study, the response times of soft tasks will be measured for each scheduling policy in several different task sets running on top of a real-time operating system (RT-Linux). The overhead of each execution will also be measured in order to determine how the overhead can affect the performance of such policies.
