Abstract:
The growing number of applications and processing units in modern MPSoCs comes along with dynamic and diverse workload characteristics at runtime. Thus, the communication infrastructure, e.g., Networks-on-Chip (NoC), operation on time dependent dynamic traffic loads makes adaptive congestion and load management indispensable. This paper introduces a centralized adaptive path management for oblivious source routing. Thereby, a cluster-based, runtime-configurable software solution continuously monitors the global traffic situation and calculates the needed routing adaptations for each active source-destination pair of the current workload inside a cluster. Contrary to other published solutions, a HW/SW-Co-Design for configurable clustering, traffic monitoring and path calculation is applied. Furthermore, the isolation of workload fractions by the spatial clustering allows application specific configurations.
