The present paper describes an extension to real-time analysis of earliest-deadline first (EDF) scheduled embedded systems to allow design space exploration with different intertask communication. The event stream approach for real-time analysis is generalized to unbuffered task communication. Adding this analysis technique to a well known cost model for system level synthesis, it becomes possible to explore different communication architectures of embedded systems by existing optimization algorithms.
