New approach to calculate energy on NoC

Low scalability and power efficiency of the shared bus in SoCs is a motivation to use on chip networks instead of traditional buses. In this paper we have modified the Orion power model to reach an analytical model to estimate the average message energy in K-Ary n-cubes with focus on the number of virtual channels. Afterward by using the power model and also the performance model proposed in [11] the effect of number of virtual channels on energy-delay product have been analyzed. In addition a cycle accurate power and performance simulator have been implemented in VHDL to verify the results.
