As bus lengths on multi-hundred-million transistor SOCs (Systems-On-a-Chip) grow and as inter-wire capacitances of sub-0.10u technologies increase, the resulting high switching capacitances of buses (and interconnects in general) have a non-negligible impact on the power consumption of a whole SOC.In this paper, we address this problem by intoducing our bus encoding technique 'ADES' that minimizes the power consumption of data buses through a dictionary-based encoding technique.We show that our technique saves between 18% and 40% of bus energy compared to the non-encoded cases using a large set of (freely-acesssible) real-world applications.Furthermore, we compare our technique to the best-known data bus encoding techniques to date and it exceeds all of them in energy savings for the same set of applications.The additional hardware effort for our bus en/decoder is thereby very small
