Bandwidth-Aware Application Mapping for NoC-Based MPSoCs

Network-on-Chip (NoC) has been introduced to meet the communication challenges for on chip multi-processors and the bandwidth of NoC takes a significant role in area and power consumption of overall system. In order to minimize the bandwidth requirement of NoC, a mapping method is proposed to schedule the tasks of an application onto NoC architecture. More precisely, given the application task graph of a specific application, an ACO-based (Ant Colony Optimization) algorithm is used to map the tasks onto the NoC, such that the bandwidth requirement of NoC is minimized. The benefit of our method is evaluated by simulation and the simulation results show that our method can achieve about 48% reduction in bandwidth requirement of NoC compared to the state-of-art method.
