Performance aspects of real-time systems

Design of real-time systems needs to take into account their performance behaviour before their implementation. This goal can be attained by means of queueing network modelling. To process this kind of models normally simulation is used with its inherent costs of debugging and running times. This paper presents the analysis and comparison of analytic (simple queues, decomposition aggregation) and simulation performance models of some basic software elements used in the construction of real-time systems.<
