Xilinx 三态以太网 MAC 核是可参数化内核，特别适于交换机和路由器等网络设备。
The TEMAC core is ideally suited for the development of high density Gigabit Ethernet communications and storage equipment.The Xilinx Tri-Mode Ethernet MAC core is a parameterizable core ideally suited for use in networking equipment such as switches and routers. The customizable TEMAC core enables system designers to implement a broad range of integrated Ethernet designs, from low cost 10/100 Ethernet to higher performance 1 Gigabit ports. The TEMAC core is designed to the IEEE 802.3 specification and operates in 1000Mbps, 100 Mbps, and 10 Mbps modes. In addition, it supports both half and full duplex operation. In 1000 Mbps mode, the TEMAC core interfaces with industry standard PHY devices through a GMII/RGMII interface. In 10/100 Mbps mode, the TEMAC uses the MII interface. The Xilinx Tri-Mode Ethernet MAC, combined with the Ethernet 1000BASE-X PCS/PMA or SGMII core, provides a complete and highly flexible solution for the implementation of Ethernet Link and Physical layers. The TEMAC core is delivered through the Xilinx CORE Generator™ tool and is part of the comprehensive suite of Xilinx Ethernet solutions.
