Ethernet 10/100 MAC Ethernet controller is compliant to IEEE802.3 and it provides interface between the host subsystem and the Media Independent Interface (MII). The 10/100 Ethernet MAC consists of DMA (TX DMA, RX DMA), TLI (TX buffer, RX buffer), 10/100 Ethernet controller. The DMA automates data transfers and frees the CPU from this task. The Transaction Layer Interface (TLI) is a 64-bit wide block designed to provide a bridge between the DMA controller and a 10/100 Ethernet controller. The TLI uses 4 Kbytes FIFO for transmit (TX Buffer) and 2 Kbytes FIFO for receive (RX Buffer).


TCP/IP off load engines 10/100 TCP/IP off load engine is a stateless TOE engine. Amongst other features it has TCP segmentation offload (TSO) in which TCP layers passes a very large segment through the stack to the TOE HW, which segments i\t into several packets. This method improves performance by reducing per packet software overheads within the network stack. The segmentation is performed inside HW. Other important offloads handled by the TOE block are TCP, UDP and IP checksum calculation and verification. With TOE engine programmed TCP/IP software stack need not calculate and update checksum fields in the protocol headers.
