Abstract

The Simplex Architecture facilitates the building of dependable and upgradable real-time systems. Before using the technology, potential users want to know more about the costs of adopting the Simplex paradigm compared to the benefits of using it. This paper examines Simplex performance and the costs associated with its use.
