Two power-reduction techniques are exploited to design a low leakage power NoC switch. First, the adaptive virtual channel (AVC) technique is presented as an efficient way to reduce the active area using a hierarchical multiplexing tree of VC groups. Second, power gating reduces the average leakage power consumption of the switch by controlling the supply power of the VC groups. The traffic-based virtual channel activation (TVA) algorithm is presented to determine traffic load status at the NoC switch ports. The TVA algorithm optimally utilizes virtual channels by deactivating idle VC groups to guarantee high leakage power saving without affecting the NoC throughput.

In network-on-chip (NoC), the data transferring by virtual channels can avoid the issue of data loss and deadlock. Many virtual channels on one input or output port in router are included. However, the router includes five I/O ports, and then the power issue is very important in virtual channels. In this paper, a novel architecture, namely, Smart Power-Saving (SPS), for low power consumption and low area in virtual channels of NoC is proposed. The SPS architecture can accord different environmental factors to dynamically save power and optimization area in NoC. Comparison with related works, the new proposed method reduces 37.31%, 45.79%, and 19.26% on power consumption and reduces 49.4%, 25.5% and 14.4% on area, respectively.

Low leakage power with maintained high throughput NoC is achieved. Traffic-based Virtual channel Activation algorithm (TVA) is proposed to activate/deactivate virtual channels in a NoC. The proposed algorithm implements Adaptive Virtual Channel technique of switching-OFF idle virtual channels in the NoC according to traffic heaviness. TVA is an efficient and flexible algorithm which provides set of parameters to be tuned and combined to achieve high performance and high power saving. NoC average leakage power has been reduced by 73.5% with negligible less than 1% degradation in throughput.
