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.

1. What are the features of the TEMAC core?

The core supports half and/or full-duplex operation, and is designed to the IEEE 802.3-2002 standard specification. Also, TEMAC core supports three different modes, 1 Gbps, 100 Mbps, 10Mbps, of operation. In addition, it provides support for VLAN frames and JUMBO frames of unlimited length. It also provides optional network management features including per packet based statistics vector and flow control. The TEMAC core can be configured and monitored through a processor independent interface, providing users the additional flexibility to pick the ideal processor for their applications.

2. What interfaces does the TEMAC IP core support?

The new TEMAC core is a parameterized core which may be configured with any one of the following three interfaces:

In the Gigabit Mode, TEMAC supports Gigabit Media Independent Interface (GMII) and Reduce Gigabit Media Independent Interface (RGMII). GMII is a byte-wide parallel SDR Interface running at 125 MHz, whereas RGMII is nibble-wide parallel DDR Interface running at 25 MHz to provide 1 Gbps total bandwidth. Also, TEMAC supports MII interface for both 100 and 10 Mbps modes. MII interface is 4-bit wide and runs at 25 MHz in the 100MBps mode. MII interface runs at 2.5MHz in 10 Mbps mode.

11. Has the TEMAC core been verified in hardware?

The Tri-Mode MAC and the client loopback example design delivered with the core have been tested in hardware (ML320 platform) in a Virtex-II Pro. The embedded PowerPC was used to access all configuration and status registers of the core. The GMII/MII of the core was connected to an external BASE-T PHY and the core tested in both full and half duplex modes and at all three speeds. Link Partners used for testing included NIC cards and an Agilent RouterTester 900.

TEMAC has also been verified in ML401 and ML403 Platforms (Virtex-4). Please refer to XAPP443 for more information.
