Perfect Difference Network for Network-on-Chip Architecture

Vol. 9  No. 12  pp. 286-290


Network-on-Chip (NoC) is a new paradigm for designing core based System-on-Chip. Network-on-Chip has been proposed as a solution for addressing the design challenges of future high performance nanoscale architectures. Innovative system-level performance models are required for designing NoC based architectures. In this paper, we discuss the possibility of achieving the energy-aware NoC architecture based on the mathematical notion of Perfect Difference sets (PDS). We present the analytical energy model for NoC platform using Perfect Difference Network (PDN). The proposed energy model is then validated against the simulation results obtained with Inter-tile link geometry and PDN circular geometry for NoC architecture. Significant energy saving is achieved for Perfect Difference Network with circular geometry in comparison with inter-tile geometry of NoC architecture on the basis of our proposed energy model.
