Reduction Of Energy Consumption in NoC Through The Application Of Novel Encoding Techniques

With the advancement of technology, the power consumed by network on chip connections (NOCs), particularly routers and network interfaces, comes into the picture to compete with the power consumed by other network communication subsystems. This paper provides a set of data coding techniques for reducing NoC connection power consumption. The proposed techniques are generic and transparent in terms of the NoC fabric (i.e. no changes to routers or connection design). Experiments on simulated and real-world traffic demonstrate that the suggested methods can save more than 50% of power dissipation and less than 15% reduction in energy consumption without compromising performance with reduced percentage area overhead in network interfaces.
