PROJECT TITLE :

Data Encoding Techniques for Reducing Energy Consumption in Network-on-Chip (2014)

ABSTRACT :

The power dissipated by the connections of a network-on-chip (NoC) begins to compete with the power dissipated by the other elements of the communication subsystem, namely routers and network interfaces, as technology shrinks (NIs). We present a set of data encoding schemes in this paper aimed at reducing the power dissipated by NoC connections. For the underlying NoC cloth, the proposed schemes are general and transparent (i.e., their application does not require any modification of the routers and link architecture). Experiments performed on both synthetic and real-world traffic conditions illustrate the feasibility of the proposed systems, allowing up to 51% of power dissipation and 14% of energy consumption to be saved without any noticeable output loss and less than 15% of overhead in the NI.
