Abstract

This paper proposes two crosstalk-aware signaling techniques based on pulse width modulation (PWM) for energy-efficient on-chip global busses. Two bits of information are encoded into transition type and pulse width for transmission over one wire. Measurements from 5mm on-chip links in 65nm CMOS show that the proposed schemes simultaneously achieve 15% performance improvement, 46% peak energy reduction, up to 25% average energy reduction, and >2X leakage reduction compared to conventional repeaters.
