During the last years, different projects and initiatives addressed the main high-level research topics related to mixed criticality: certification by design, reconfiguration, fault detection, fault isolation and redundancy. However, some important challenges remain, being one of them the power consumption management and optimization in dependable mixed-criticality systems. Power is another resource (together with time and space) that has to be shared among different applications and the available energy has to be shared by all running applications in a mixed criticality system. SAFEPOWER will advance the state-of-the-art towards a low-power reference architecture combining periodic time-triggered and event-triggered rate-constrained activities with power-efficient techniques for fault isolation, temporal predictability and determinism.
SAFEPOWER has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 687902.
SAFEPOWER’s goal is to enable the development of low power mixed-criticality systems through the provision of a reference architecture, platforms and tools to facilitate the development, testing, and validation of these kinds of systems according to the market needs
It is expected that the SAFEPOWER reference architecture and platforms will enable the integration and partitioning of mixed-criticality applications on a single device while reducing the total power consumption by 50%, compared to the non-integrated multi-chip implementation. To address this goal, SAFEPOWER needs to address a number of technology development challenges, that will afterwards be applied to the main project outputs, namely the SAFEPOWER low power reference architecture, the platforms and tools for the development, testing, and validation of low power mixed criticality systems.
