Reducing energy consumption using data encoding techniques in network on chip

Abstract

The links of network on chip(NOC) power dissipation compete with the power dissipation of other elements of the communication subsystem, namely, the routers and network interfaces(NIs). A set of data encoding schemes aimed at reducing the power dissipation in the links of an NoC. Self switching activity and coupling switching activity are responsible for reducing the power dissipation. Thus, both the switching activities with the three data encoding schemes has been proposed to reduce the power dissipation and energy consumption. Experiments carried out on both synthetic and real traffic scenarios and it shows the effectiveness of the proposed schemes, which allow to reduce the power dissipation and energy consumption.
