Abstract : In this paper, a Transition Based Odd/Full Invert (TBO/FI) coding scheme, which focuses on crosstalk avoidance and low dynamic power consumption in NoC links is proposed. This scheme is designed and implemented at both architectural and logic level and is evaluated using synthetic traffic scenarios for both 4- and 8-wire links. All the evaluations are performed for the worst-case, the best-case, and the typical-case scenarios. TBO/FI coding scheme has the maximum reduction percentage for both the switching activities in all the cases for 4-wire link and same is true for 8-wire link except for the worst-case scenario. TBO/FI coding scheme allows NoC power savings of up to 25.5% and 40.4% for 4- and 8-wire links with worst-case scenario and with other scenarios, NoC power consumption increases. However, this increase is lower than that of other existing schemes. These results are achieved despite the NoC router area and power overheads of 117% and 50% for 4-wire and 52% and 26% for 8-wire link, respectively. NoC router area and power reduces by 16% and 30%, respectively, with increase in link width and this reduction is more compared to all other schemes.
