Modified weighted code with bit invert approach to minimize crosstalk in network on chip links

In this paper, an efficient CODEC design is proposed for generating forbidden pattern free crosstalk avoidance code. The proposed modified weighted code with bit invert (MW-BI) approach minimize the worst case cross talk delay by avoiding the triplet opposite direction (TOD) transition entirely in the Network on chip links. The MW-BI CODEC is implemented using synopsys design compiler tool and mapped on SAED 90 nm technology library. The implementation results show that the proposed MW-BI CODEC method decreases the Total Area by 30.05, 41.48 and 34.71% compared to already existing FIBO, IMP FIBO and S2AP CODEC respectively, and also achieves less Total Dynamic Power of 43.40, 53.72 and 50.92% than others. And also the proposed technique reduces the Cell Leakage Power by 16.33, 17.23 and 29.39% when compared to other cross talk avoidance coding methods.
