On the design of reconfigurable crossbar switch for adaptable on-chip topologies in programmable NoC routers

摘要

Research works have focused on high-performance on-chip interconnections with low cost and energy consumption for the next generation of many-core processors. In the same way, parallel applications will explore thread level parallelism and message-passing communication through a Network-on-Chip (NoC) to perform a high data throughput. Due to the dynamic changing of communication patterns, the goal of this paper is to present the design of Reconfigurable Crossbar Switch for NoC Routers (RCS-NR) capable of adapting topologies on demand. RCS-NR has an optimized architecture, similar area and lower energy consumption (up to 87.41%) relative to a traditional crossbar switch. Furthermore, RCS-NR-based NoC router has a similar area, higher throughput, and it is up to 98.76% more efficient in energy consumption than a conventional NoC.
