In this paper, we propose using joint equalization and coding to improve on-chip communication speeds by signaling at rates beyond the rate governed by resistance-capacitance (RC) delay of the interconnect. Operating beyond the RC limit introduces inter-symbol interference (ISI). We mitigate the effects of ISI by employing equalization. The proposed equalizer employs a variable threshold inverter whose switching threshold is modified as a function of past output of the bus. We demonstrate even… CONTINUE READING
