DualBLESS: Bufferless Router with Dual Ejection Ports for 2D and 3D NoC

In this paper, the authors proposed a 1-cycle bufferless router with dual ejection ports (which is also called DualBLESS) for 2D and 3D Network-on-Chip. The router uses a simple route computer module, a MUX module instead of the Flit Ejector module and a MUX module in a baseline bufferless router to achieve high performance. Simulation results under six synthetic workloads illustrate that the two proposed DualBLESS routers achieve less average packet latency and higher throughput than the baseline 2D and 3D bufferless routers.
