Special Section on Energy-Efficient Technologies:NoC Circuits, Architectures, and Systems

Energy consumption has been one of the major challenges and concerns for the electronic devices design, especially in high-performance multi- and many-core systems. A highly integrated many-core chip is prone to be extremely high-power consumption that exceeds the chip＇s power budget set leaded by cooling, packaging and/or the capacity of the power supply. When this situation happens, various parts of the many-core chip will have to be deliberately switched off （darkened） so that the chip is still in compliance with its power budget, which is referred as ＂dark silicon＂. Therefore, the research on energy efficient computing is a current trend and will continue to be an active area in the coming years.
