A SRNoC-based adaptive routing scheme for network-on-chip

Aiming at achieving high-performance and efficient routing in network-on-chip, a new adaptive STR routing algorithm is proposed based on SRNoC topology in this paper. The proposed routing algorithm can choose the routing paths dynamically and enables the routing hops within 2 between any source nodes and destination nodes. It is mainly made up of router injection port selection and TM output port computation. The proposed adaptive STR routing is designed and implemented in RTL level by Verilog HDL. Compared with SRNoC scheme, experimental results show that the proposed routing could improve the network saturation injection rate and throughput by 93.5% in average under four synthetic traffic patterns while just a little hardware overhead is introduced.
