A low power SoC bus with low-leakage and lowswing technique

A novel low power SoC bus with low-leakage and low swing technique is proposed. The repeater used in the bus lines effectively reduces leakage power through stacking effect, not losing its logic values even in sleep mode. The proposed SoC bus reduces not only the leakage power in the normal active/sleep mode but also both dynamic and leakage power in the low swing operation mode. The proposed scheme reduces the total power by 44.5% compared to the conventional SoC bus architecture.
