A Hybrid Performance Analysis Technique for Distributed Real-Time Embedded Systems
It remains a challenging problem to tightly estimate the worst case response
time of an application in a distributed embedded system, especially when there
are dependencies between tasks. We discovered that the state-of-the art
techniques considering task dependencies either fail to obtain a conservative
bound or produce a loose upper bound. We propose a novel conservative
performance analysis, called hybrid performance analysis, combining the
response time analysis technique and the scheduling time bound analysis
technique to compute a tighter bound fast. Through extensive experiments with
randomly generated graphs, superior performance of our proposed approach
compared with previous methods is confirmed.Comment: 29 pages (25 page paper, 4 page appendix), 16 figure
