Data Encoding Technique Using Gray Code in Network-on-Chip

Abstract

As technology varies the power dissipated by the links of a network-on-chip (NOC) due to noise increases the risk of errors in the communication subsystem. In this paper, we present a data encoding technique using gray code input aimed at reducing the errors and power dissipation by the links of an NOC. The proposed scheme uses the binary to gray conversion at the transmitter and gray to binary conversion at the receiver. An experimental result from both synthetic and real traffic scenarios shows the effectiveness of the proposed schemes which allows to save the power up to 21.6% and reduces the noise or error during the transmission through the encoder using Gray code.
