Reduction of Energy Consumption in Noc by Using Encoding Techniques

Abstract

This paper mainly focuses on reducing the consumption of energy by the power dissipated links of a network on-chip (NoC - Network on Chip) which starts to compete with the power dissipated by the other elements of the communication subsystem like the routers and the network interfaces (NIs). It provides a set of data encoding and decoding schemes aimed at reducing the power dissipated by the links of a NoC. The proposed schemes are general and transparent with respect to the underlying NoC Architectures. The paper provides few techniques to overcome the power dissipation by self switching activity and coupling switching activity. The proposed schemes has been implemented on Xilinx FPGA of Spartan-6 Family and it shows that 51% of power dissipation and 14% of energy consumption is saved and 15% area overhead in the NI is achieved without affecting the performance
