ROCK: Robust Network On Chip Communication Through Hierarchical Online Diagnosis and Reconfiguration
The project ROCK targets the analysis and the prototypical development of robust architectures and associated design practices for Networks-on-Chips. Thereby, it meets the challenges of increased susceptibility of on-chip communication infrastructures against the massive influences caused by escalating integration density. ROCK pursues the strategy of conducting fault detection, online diagnosis und specific reconfiguration to tackle faults in a hierarchical manner throughout all network layers, aiming at selecting an optimal combination of activities over all layers. The quality of potential solutions is measured by their energy-minimal compliance to assurances made with respect to the performability of the network. For this purpose, performability will be defined for the research area of NoCs, incorporating communication performance and fault statistics. Any algorithms and architectures for controlling and performing diagnosis and reconfiguration shall themselves be designed as fault tolerant. Furthermore, their operation shall be transparent to the application processes and minimize interference with regular NoC communication. A wide range of architectures will be investigated based on the enabling technology of NoC fault models and high-level NoC fault simulation.
