Application-specific Network-on-Chip (NoCs) allows optimization for the interconnection to minimize its cost. When used with streaming applications, large flows of data can be predicted. However, these flows can be modified during the applications providing a dynamic flow graph. In that case, applying on off-line optimization leads to an over-sizing of the NoC. On the other hand, dynamic reconfiguration leads to unordered data deliveries with costly re-ordering units. In this paper, the authors propose a coarse grain dynamic reconfiguration which avoids data re-ordering requirement.
