On-chip networks have been proposed as the interconnect fabric for future systems-on-chip and multi-processors on chip. Power is one of the main constraints of these systems and the interconnect consumes a significant portion of the power budget. In this paper, we propose four leakage-aware interconnect schemes. Our schemes achieve 10.13%-63.57% active leakage savings and 12.35%-95.96% standby leakage savings across schemes while the delay penalty ranges from 0% to 4.69%.
