Abstract

In many complex embedded systems, real-time workload is generated conforming certain structural constraints. In this paper we study how to analyze the delay of real-time workloads of which the generation pattern can be modeled by task graph models. We first show that directly combining path abstraction technique (PAT) in real-time scheduling theory and real-time calculus (RTC) can provide safe delay bounds, but the results are typically over-pessimistic. Then we propose new algorithms to efficiently and precisely solve the delay analysis problem. Experiments with randomly generated task systems are conducted to evaluate the performance of the proposed methods.
