Over the decades, autonomous vehicles have been developed and qualified using variant single-core architectures. With the evolutionary trend of safety critical applications, innovative safety design methodologies have raised present requirements constraints and limitations to mitigate such design complexity deviations. The main objectives of this work are to investigate, evaluate and introduce an efficient safety-critical multi-cache multicore architecture, that is fully compliant with methods and principles of ISO 26262. Moreover, this paper presents new safety design choices applied to timing monitoring, temporal protection, runtime monitoring and services protection to overcome multicore processor challenges in runtime that eventually decay the worst case execution time and the interconnections (symmetric and asymmetric processors, critical timing, data coherency and synchronization predictability, core interconnects, etc.), as well as to tolerate real-time interference faults.
