Crosstalk-aware link power model for Networks-on-Chip

Networks-on-Chip (NoCs) are recognized as the solution to address the communication bottleneck in Multiprocessor System-on-Chip (MPSoC). As the NoC represents a significant part of the system power consumption, MPSoC designers expect accurate power models in order to produce energy efficient systems. Nowadays, NoC simulators rely on power models that integrate link models without crosstalk modeling. In this work, we present a link power model with crosstalk modeling embedded in a NoC simulator. We show that the crosstalk effect has a deep impact on NoC energy consumption since our results demonstrate that classical models generate errors up to 45.5% on the whole NoC energy consumption estimation.
