Dynamic Self-Shielding Bus Encoding for Signal Integrity Enhancement and Low Power in NOCs

As feature sizes shrink and clock frequencies increase, Signal integrity and power consumption face critical challenges in design and implementation of NOCs (network-on-chip). A kind of dynamic self-shielding bus encoding scheme is proposed in this article. This scheme aims to provide a high degree of signal integrity through dynamic self-shielding technique and to reduce bus power consumption in NOCs. Qualitative comparisons between our scheme and other state-of-the-art approaches showed that this encoding scheme enhances signal integrity and decreases bus power consumption.
