Negative Exponential Distribution Traffic Pattern for Power/Performance Analysis of Network on Chips

In this paper, we propose a synthetic traffic model based on Negative Exponential Distribution (NED). This synthetic traffic profile is more similar to some statistical behavior of realistic traces obtained by running different applications on Network-on-chips that those of conventional synthetic traffic profiles. To assess usefulness of this traffic model, the average packet hops for the proposed traffic profile is compared with those of some synthetic and realistic traffic patterns obtained from running applications on NoCs. The results show that the NED traffic profile has more similarity with the realistic traffic profiles than those of conventional synthetic ones.
