Low leakage power NoC switch using AVC

Low leakage power switch is proposed to allow saving in power dissipation of the Network on Chip (NoC). The proposed NoC switch employs power supply gating to reduce the power dissipation. Two power reduction techniques are exploited to design the proposed switch. Adaptive Virtual Channel (AVC) technique is proposed as an efficient technique to reduce the active area using hierarchical multiplexing tree. Moreover, power gating reduces the average leakage power consumption of proposed switch. The proposed techniques reduce the leakage power of the switch by up to 97%. In addition, the dynamic power is reduced by up to 54%.
