- Reducing power consumption is a main challenge when adopting a network as a global on-chip communication interconnect since the reduction in power dissipation should not at the expense of degrading the system performance. We investigate power in a wormhole-switched network with focus on the impact of flit-admission schemes, i.e., when and how the flits of packets are admitted into the network We have proposed a novel flit-admission scheme that shows significant shrink of the switch complexity while maintaining equivalent network performance. This paper investigates its influence in network power involving both switches and links. We conduct experiments on a 2D mesh network. The results show that our flit-admission scheme achieves significant power and area reduction without performance penalty. To our knowledge, our work is the first study of power dissipation on flit admission schemes.
