Flit Inversion Techniques for Reducing EnergyConsumption in NoC

The dynamic power dissipation in the NOC is mainly due to coupling effects between on chip interconnections in deep submicron VLSI designs. Coupling effect between the interconnections not only enhances power-delay product but also decreases the signal to noise ratio and increases signal distortion due to cross talk noise obtained by capacitance and inductance.as technology shrinks the power consumption in NOC links is start compete with the NOC routers. In this paper we proposed flit inversion techniques which reduces both coupling activity in adjacent links and self-switching activity in particular data links. Before data enters into network interface we encode the data flit and decode at destination end of the NI.. From the result we get the reduction in power and energy consumption areup to 35% and 20%, without degradation of performance
