Data Flipping Coding Technique to Reduce NOC Link Power

Power consumed by Network on Chip (NoC) plays significant role in the power budget of the System on Chip (SoC). In NoC, links consumes almost quarter of the power. Transition count in the link have to be reduced to reduce the switching activity and hence its dynamic power. Many techniques have been introduced to reduce the transition count. This paper presents a unique data coding technique through which the transition count can be reduced in parallel data transmission. This technique reduces an average of 61.42 percentage of link power with less area compared to quadro and multi coding techniques. The proposed technique, which is applicable for any data width, achieves 17% power saving of the total network used for demonstration.
