Dynamic Voltage and Frequency Scaling

The performance advantages of millimeter-wave SWNoC (mSWNoC) mainly stem from using the wireless links as long-range shortcuts between far apart cores. This performance gain can be enhanced further if the characteristics of the wireline links and the processing cores of the mSWNoC are optimized according to traffic patterns and workloads. This chapter focuses on incorporating both processor- and network-level dynamic voltage and frequency scaling which can enhance the power and thermal profiles of the Network-on-Chip without a significant impact on the overall execution time. Also, depending on the benchmark application, temperature hotspots can be formed in either the processing cores or the network infrastructure. This chapter addresses both these types of hotspots.
