In this talk we discuss the current design challenges for embedded systems, suffering pressures from the market, technology and software development. After discussing the context, we introduce some first steps in the direction of having software productivity with high reliability and low energy dissipation. We present RA3, the Resilient Adaptive Algebraic Architecture, which is capable of adapting parallelism exploitation in a time-deterministic fashion to reduce power consumption, while meeting the existing real-time deadlines. Furthermore, the architecture provides low overhead error correction capabilities, through the use of algebraic properties of the operations it performs. We use two real-time industrial case studies to validate the architecture and to show how the adaptive exploitation works. Finally, we present the results of fault-injection campaigns to show the architecture resilience against soft-errors.
