Abstract
Systems and methods described herein are directed to solutions for Network on Chip (NoC) interconnects that automatically and dynamically determines the number of layers needed in a NoC interconnect system based on the bandwidth requirements of the system traffic flows. The number of layers is dynamically allocated and minimized by performing load balancing of the traffic flows between the channels and routes of different NoC layers as they are mapped. Additional layers may be allocated to provide the additional virtual channels that may be needed for deadlock avoidance and to maintain the isolation properties between various system flows. Layer allocation for additional bandwidth and additional virtual channels (VCs) may be performed in tandem.
