Modified Pre-Encoder For Eti Coding Scheme

Serial communications are more efficient to parallel communications as we humans are advancing to an age where every electronic devices are to be as portable as possible, the use of parallel buses needs to be avoided since these increases the requirement of space on a die. ETI schemes are now a days used for serial communications, the merit of which is to reduce the switching activity. This coding scheme is better that that of TIC scheme, which consumes more power. In this paper we are modifying the ETI-Pre encoder in encoding part to that of its predecessor, which resulted in power reduction. The simulations are done in Xilinx.
