10/100 Mbit Ethernet MAC

Overview

The GRETH is a 10/100 Mbit/s Ethernet MAC controller IP with AMBA host interface

The GRETH core implements a 10/100 Mbit/s Ethernet Media Access Controller (MAC) with AMBA host interface. The core implements the 802.3-2002 Ethernet standard. Receive and transmit data is autonomously transferred between the Ethernet MAC and the AMBA AHB bus using DMA transfers.
