Low-swing on-chip signaling techniques: effectiveness androbustness

摘要

This paper reviews a number of low-swing on-chip interconnectnschemes and presents a thorough analysis of their effectiveness andnlimitations, especially on energy efficiency and signal integrity. Innaddition, several new interface circuits presenting even more energynsavings and better reliability are proposed. Some of these circuits notnonly reduce the interconnect swing, but also use very low supplynvoltages so as to obtain quadratic energy savings. The performance ofneach of the presented circuits is thoroughly examined using simulationnon a benchmark interconnect circuit. Significant energy savings up to anfactor of six have been observed
