Enhanced Three-Speed Ethernet Controllers
14.1
Overview
The enhanced three-speed Ethernet controllers (eTSECs) of the device interface to 10 Mbps, 100 Mbps,
and 1 Gbps Ethernet/IEEE 802.3™ networks and devices featuring generic 8-bit FIFO ports. For Ethernet,
an external PHY or SerDes device is required to complete the interface to the media. Each eTSEC supports
multiple standard media-independent interfaces, of which the FIFO interface bypasses the Ethernet MAC.
Multiple eTSECs are available, providing flexible options for connectivity and control access at different
speeds.
The eTSEC provides the flexibility to accelerate the identification and retrieval of standard and
non-standard protocols carried over Ethernet, including both IP versions 4 and 6 and TCP/UDP.
CPU-intensive parsing and checksum operations can be optionally off-loaded to an eTSEC to accelerate
existing TCP/IP stacks. On transmission, varying fractions of link bandwidth can be allocated to each of
multiple transmit queues through a modified weighted round-robin scheduler. On receive, an arbitrary set
of queue selection rules can be programmed into each eTSEC to implement flexible quality of service or
firewall strategies based on high-level protocol identification. Without enabling these advanced features,
each eTSEC emulates a PowerQUICC TSEC, allowing existing driver software to be re-used with
minimal change. Each eTSEC is organized as shown in
Figure
