Energy Models for Communication of Future Computing Platforms

Energy efficiency is an essential requirement on future computer architectures. Thereby, the efficiency of the communication will play an important role. Within this paper, we present an energy model for a unicast multi-hop communication. The model allows to derive predictions about the energy of a future computing platform. Further, it can be used to identify which components of the system or tasks related to communication have a significant influence on the overall energy and, hence, require special attention in the design phase. We discuss how values for processing delays and power consumption can be determined for a future computing platform and present values for a target platform. The energy model is applied to derive energy predictions for this platform.
