GMAC

Core Features

This document is the Ethernet Controller IP (XEC)’s user manual.
XEC is a high performance 1000M/100M/10M Ethernet Controller IP. It support GMII/RGMII/MII/RMII MAC-PHY interface and support AXI/AHB system bus.
XEC can receive the data from Ethernet PHY to the AXI/AHB bus, and to send out data from AXI/AHB bus to the Ethernet PHY.

10/100/1000 full-duplex, 10/100 half-duplex. The customer can choose only support 10/100M when configure the IP.
GMII/RGMII/MII/RMII interface.
AXI/AHB system interface. The customer can choose AXI or AHB interface when configure the IP.
Compliant with IEEE 802.3-2008 standard and IEEE 802.3az standard.
Support to configure the total rx and tx SRAM size with the value of 8KB, 12KB, 16KB and 24KB. The customer can choose the size when configure the IP
Up to 32 additional 48-bit mac source address filter with mask for each byte. The customer can choose the number from 0 to 32 when configure the IP.
Up to 32 additional 48-bit mac destination address filter with mask for each byte. The customer can choose the number from 0 to 32 when configure the IP.
