Using binary-reflected gray coding for crosstalk mitigation of network on chip
Zahra Shirmohammadi, Seyed Ghassem Miremadi · 2013
This paper proposes an efficient crosstalk mitigation method for Network-on-Chips. This method uses the binary-reflected Gray coding to send the proper code word into a channel. As the Gray code has reflective and unit distance properties, based on these facts, content of every flit is selected so that to minimize the number of forbidden transition patterns in the channel. A VHDL-based simulation is carried out for several channel widths. Simulation results show that the proposed method reduces the forbidden transitions up to 26% and can save power in NoC links.
