Dynamic reconfiguration in NoC-based MPSoCs in the avionics domain

Modern Network-on-Chip-based Multiprocessor Systems-on-Chip (NoC-based MPSoCs) bear the potential for higher performance, but may also allow the concentration of the same functionality on fewer devices in a complex system such as an aircraft. Albeit these advantages the avionics industry is still hesitant to adopt multi-core technology because software requirements such as predictability have to be met to guarantee safety and reliability. The impact that the application of multi-core processors has on these requirements is not yet fully understood. Therefore our research is driven by the software requirements in the avionics domain which are relevant for the application of multi-cores. We address the dynamic aspects of the system behaviour and investigate flexible partitions and online task migration as a methodology to improve resource utilization on a shared computing platform
