Energy Performance of Network on Chip Architecture for Rectangular Perfect Difference Network Topology

Abstract

Network-on-chip architecture is a new paradigm shift for designing IP core based system on chip and also referred as network based communication subsystem which is recently looked as an innovative approach to provide a highly scalable, high computational and communication performance. Energy consumption of network based communication subsystems is becoming the valuable parameter in the design of system which further needs to be optimized. In the recent development of IP core architecture, it is necessary to propose new approach for design methodologies to minimize the communication energy for network based communication subsystems. We have addressed the Rectangular Perfect Difference Network topology for network based communication subsystems for providing optimum bandwidth utilization with lesser number of routing hops and at the most two hops in the communication to achieve the best energy performance. In this paper, we propose Rectangular PDN topology for network based communication subsystems for minimization of communication energy using the mathematical representation of Perfect Difference Set (PDS). We have proposed the analytical model with lower energy consumption for chordal Ring Perfect Difference Network Topology and Rectangular Perfect Difference Network Topology. The proposed analytical model for network based communication subsystems using Perfect Difference Network topology results is simulated and validated for different Network topology having order of n=7. The link energy model and router energy model are validated against simulation results for Rectangular PDN topology of network based communication subsystems. The overall average energy consumption for transfer of data through router from one IP to another IP for Rectangular PDN Topology for network n=7 for perfect difference set of {0, 1, 3} having order δ=2; is compared with overall average energy consumption for 2X2 CLICHÉ architecture
