The effects of traffic patterns on power consumption of torus-connected NoCs with faults

High performance, reliability, transient and permanent fault-tolerance, and low energy consumption are major objectives of Networks-on-Chip (NoCs). Since, different applications impose various communication requirements in NoCs, a number of research studies have revealed that the performance advantages of routing schemes are more noticeable on power consumption under different traffic patterns. However, the power consumption issues of NoCs have not been thoroughly investigated in the presence of faulty regions. To the best of our knowledge, this research is the first attempt to examine the effects of most popular traffic patterns (i.e., Uniform, Local, and Hot-Spot) on power consumption of NoCs in the presence of permanent faults.
