PlugSMART: a pluggable open-source module to implement multihop bypass in Networks-on-Chip

The integration of many processing elements per die makes it more difficult to provide low latency in the Network-on-Chip (NoC). Multihop bypass proposals, such as SMART, attack this problem by allowing flits to skip multiple routers in the path in a single cycle, drastically reducing latency while preserving a regular tiled layout. However, multihop bypass routers are more complex and relatively ...
