This embedded platform software is ready to be integrated in complex safety-related multi-core multi-SoCs used for automated driving. The MotionWise architecture eases integration and validation of applications by performing a separation of the available resources. Each application hosted by MotionWise will run encapsulated from its peers, resulting in a safe environment where applications with different safety and real-time requirements can coexist and interact. MotionWise offers a comprehensive set of system and integration services, providing a homogeneous platform out of SoCs of different safety or performance classes.
