Abstract

Architectures for designing soft real-time systems do not typically provide any performance tool that will enable the designer to analyse the performance of the system that is being designed. Elementary intercommunication data areas known as interaction protocols are the building blocks of every soft real-time system. The interaction protocols are grouped into families depending on their writing/reading functionality. In this chapter, we extent the interaction protocol families, that are commonly used in every soft real-time architecture, in order to describe a complete performance taxonomy. The components of this taxonomy transfer data among processes. Their performance models can be used in a software package to complement the automatic design and generation of soft real-time systems. Despite the performance of the whole system can be solved through simulation in this chapter we propose new semaphore queues as analytical approximations for most of these soft real-time components.
