To support high bandwidth SoCs, a communication design flow is necessary for the design space exploration respecting tight design requirements. In order to exploit the benefits introduced by the NoC approach for the on-chip communication, the paper presents a design flow for the core mapping and customization of the network topology applied to STNoC, the Network on-Chip developed by STMicroelectronics. Starting from ring topology, the proposed application-specific flow tries to find a set of customized topologies, optimized in terms of performance and area/energy overhead, by adding links. The generated STNoC custom topologies provide a reduced cost with respect to the spidergon topology.
