OUR WORLD – EMBEDDED DEVICES
Embedded industry evolving exponentially in various industries, some more critical than others, faces final users with limited computer science knowledges. This contrains the embedded systems designers to assure the behaviorof their systems as autonomous as possible, Nowadays such systems are software centric thus made up of a program or a set of programs executed on a processor. For industries with a high level of criticity (avionic, aumotive, railway, spatial) it is important to estimate the worst case execution time of a program (WCET) since a program taking more time than allowed may disturb the performance of the system possibly leading to catastrophic consequences. The exponential evolution of embedded systems leads to very complex programs to be run in autonomy and single core processors start reaching their limits. Therefore, using processors incorporating several cores becomes inevitable. But as inevitable as it is using multicore processors brings with it the problem of time impredictability of the programs.
Statinf analyzes the interferences caused by multicores processors that prevent the autonomy of the embedded systems as well as tackling their impredictibility. In addition to autonomy, we ensure the control of the development cycles while reducing energy consumption.
