Performance Evaluation of Real-Time Systems

Abstract

Performance evaluation of the Computer Systems has been a challenging task. Measurement of Worst Case Execution Time (WCET) is an important metrics for evaluating the performance of the Real Time Systems (RTSs). In this paper, we explore different methods used for WCET estimation. We mainly focus on three different techniques that are used for WCET estimation i.e. Static, Measurement-based, and Hybrid. The objective here is to provide a comparative analysis of various popularly used WCET measurement tools to guide researchers and engineers to be able use the most suitable techniques for their target applications. We also explore the probabilistic approach through model checking in our work.
