Abstract

This paper presents a Network-on-Chip (NoC) architecture that enables the network topology to be reconfigured. The architecture thus enables a generalized System-on-Chip (SoC) platform in which the topology can be customized for the application that is currently running on the chip, including long links and direct links between IP-blocks. The configurability is inserted as a layer between routers and links, and the architecture can therefore be used in combination with existing NoC routers, making it a general architecture. The topology is configured using energy-efficient topology switches based on physical circuit switching as found in FPGAs. The paper presents the ReNoC (Reconfigurable NoC) architecture and evaluates its potential. The evaluation design shows a 56% decrease in power consumption compared to a static 2D mesh topology.
