Network-on-Chip (NoC) is becoming a promising communication architecture in place of dedicated interconnections and shared buses for embedded systems. Nevertheless, it has also created new design issue such as communication congestion and power consumption. A major factor leading to communication congestion is mapping of application tasks to NoC. Latency, throughput, and overall execution time are all affected by task mapping. As a solution, an efficient runtime Congestion-aWare Scheduling (CWS) is proposed for NoC-based reconfigurable systems, which predicts traffic pattern based on the link utilization.
