Low Power Design of 40 Gigabit Ethernet Media Access Controller Using Hyper Transport Protocol IO Standard

Abstract

Nowadays, the low power design requirement forthe communication equipment is becoming essential for greencommunication systems. The Ethernet Media Access Controller(EMAC) is an important source interfacing the physical devices.However, the high-speed data operation consumes an enormouspower. This limits the performance of existing Ethernet MediaAccess Controllers in real-time. In this work, a novel low powerdesign of 40G EMAC is developed using Hyper TransportProtocol (HTP) IO standard technique. The designed 40G EMACis developed using Xilinx and tested for high frequencies of 5THz, 10 THz, and 15 THz. The developed 40G EMAC using HTPIO standard is consuming less power for THz frequencies. It isalso demonstrated that 70% power reduction is archived for5THz, and for 10 THz and 15 THz, 69% and 68/% powerreduction is attained respectively for 40G HTP based EMAC.The developed EMAC can be used in existing communicationsystem in order to make the green networking.
