Static Reconfiguration and Performance Evaluation of embedded software architectures

Nowadays, many domains aeronautics, automobile, household electrical appliances, industry, medicine, and so on have known a considerable development in the field of embedded systems. Indeed, embedded system is made up of two heterogeneous parts: • Material architecture composed of body, buttons, integrated circuits (Processor, ROM, RAM, and so on) • Software architecture consisting in procedures (instructions), written programming languages (Java, C, C++, and so on) integrated on microcontrollers These two entities, together, achieve complex tasks. The complexity of tasks entails certain bugs such as dysfunction, errors. These bugs are corrected by updates of embedded software architecture: this is called static reconfiguration of system. The purpose of this paper is to study bugs, their causes, their consequences and their possible reconfigurations (static reconfiguration and dynamic reconfiguration). The first reconfiguration always causes a restarting of system while the second is applied without human intervention. A study case of embedded system functioning with Stochastic Well formed Petri Nets (SWN) model is also treated in this paper.
