ReNoC: A Network-on-Chip Architecture with Reconfigurable Topology
2008
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.
