Modified bus invert encoding to reduce capacitive crosstalk, power and inductive noise

As Very Large Scale Integrated (VLSI) circuits are shrinking aggressively, interconnect length is becoming longer. So interconnect power consumption due to capacitive coupling is increasing. Again, as operating frequency is increasing and rising time is very short, the inductance effect between interconnects can no longer be ignored. So, capacitive coupling and inductive coupling are both power and performance bottlenecks of modern interconnect design. In our paper, we have proposed an encoding method of data based on odd and even inverts of encoding. Our simulation results show that peak power is due to capacitive coupling and can be reduced up to 43.64%. Average power consumption decreases by 17.38%. Inductive ringing can be minimized up to 83.33% at logic high level and up to 30% at logic low level.
