Energy and latency evaluation of NoC topologies

Mapping applications onto different networks-on-chip (NoCs) topologies is done by mapping processing cores on local ports of routers considering requirements like latency and energy consumption. In this work, an algorithm devoted to evaluate different topologies is proposed. The evaluation starts with an application model called application communication pattern (ACP), which specifies tasks with the computation load and communication profile. ACP focuses on communication aspects and is an appropriate model to obtain mappings that comply with application requirements. ACP allows fast analysis over many NoC topologies, helping the system designer to evaluate the communication performance of a NoC-based system; this performance strongly depends on the placement of the cores, and it is computationally hard to find the optimal placement.
