Prediction Based Minimally Buffered Deflection Router Interconnect, in Network-on-chip

A conventional Network-on-Chip (NoC) router uses input buffers to store packets to improve performance, but consume significant power. While bufferless NoC design has shown reduction in area and power, and offers similar performance to conventional buffered designs for many workloads, than conventional buffered routers at high network load. This degradation is a significant problem for widespread adoption of bufferless NoCs. In this work, we propose a new NOC router design called Minimally-Buffered Deflection (MinBD) Router combines deflection routing with a small buffer, which place some network traffic in this small buffer which would have been deflected otherwise. And using the prediction flow control technique for the side buffer. The side buffer would generate status signals, which are sent out to neighboring router switches, would help control the congestion in the network, by predicting the routing flow.
