Abstract

The most important things in real-time systems are that a system guarantees to meet its deadline and to operate in its predictable range. When we design a real-time system, we need to verify whether the system can meet its deadline through schedulability analysis. There are several kinds of schedulability analysis technique for fixed priority scheduling systems. But as we all know, we can't perform schedulability analysis in design time because we can't estimate upper bounds on execution time of each task. So we used a similar real-time system to estimate upper bounds on execution time for our system, and then we performed schedulability analysis and verified that our system designed can meet its deadline.

Key Words: Schedulability Analysis, Fixed Priority Scheduling, Real-Time System
