Serial link interconnection has been implemented for its advantages of reducing crosstalk and area. However, serializing parallel buses tends to increase bit transition and power dissipation. Several coding schemes, such as serial followed by encoding (SE) and transition inversion coding (TIC), have been proposed to reduce bit transition. TIC is capable of decreasing transitions by 15% compared to the SE scheme, but an extra indication bit is added in every data word to represent inversion occurrence. The extra bit increases the transmission overhead and the bit transitions. This paper proposes an embedded transition inversion (ETI) coding scheme that uses the phase difference between the clock and data in the transmitted serial data to tackle the problem of the extra indication bit. Proposed coding scheme is design and implemented using Xlink tool. power is calculated using Xpower and result shows that ETI consumes 52 (mw) power and TIC consumes 65.2(mw) shows that ETI is optimized technique than the TIC.
