In this paper, the authors propose a flit-level speedup scheme to enhance the Network-on-Chip (NoC) performance utilizing bidirectional channels. In addition to the traditional efforts on allowing flits of different packets using the idling internal and external bandwidth of the bi-directional channel, their proposed flit-level speedup scheme also allows flits within the same packet to be transmitted simultaneously on the bi-directional channel. For inter-router transmission, a novel distributed channel configuration protocol is developed to dynamically control the link directions.
