Improved Schedulability Analysis of Fixed-Priority for Mixed-Criticality Real-Time Multiprocessor Systems

摘要

In real-time systems, timing guarantees on real-time tasks are the most important requirement. The requirement, however, causes inefficient resource usage due to over-estimated (but safe) task execution time, which brings the advent of the concept of Mixed-Criticality (MC). In this paper, we improve an existing schedulability analysis of Fixed-Priority (FP) scheduling on MC systems. Our evaluation results demonstrate the effectiveness of our analysis in terms of schedulability.
