Abstract: Here, in this project; embedded transition inversion (ETI) is proposed to reduce bit transitions in Serializing parallel buses. Implies power can be reduced further. This project 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. The technique is implemented in an optimized fashion using pipelining so that it can be used in practical systems with only a slight compromise in performance. This is achieved by calculating the decision as the data is being loaded on to the buffer and doing the encoding on the fly. This is one aspect which is lacking in most existing algorithms as they are not amenable to low delay implementation. As an enhancement B2I block is eliminated by using master slave flip-flop. Bit2 inversion output is yielded without using B2I block. Furthermore area can be reduced with this enhancement.

 INTRODUCTION 

            Low power design, in a system perspective, happens at all levels of the digital electronic system stack. It is being done from the lowermost device level design to the topmost software design. And there are the intermediate levels where a lot of effort is being expended to make systems run at low power, keeping the compromise in performance to be minimum. The increasing density of the integrated circuits as postulated by Moore’s law makes it even more important to have low power systems since the power supply for such a dense integrated circuit may not keep track in size with the miniaturization of the electronic components. Hence research is being made at all levels of a system stack. A system can consist of multiple components. They can be broadly classified and a communication framework designed work.
