Description

The SONIC-T (Systems-Oriented Network Interface Controller with Twisted Pair) is a second-generation Ethernet Controller designed to meet the demands of today's high-speed 32- and 16-bit systems. Its system interface operates with a high speed DMA that typically consumes less than 5% of the bus bandwidth. Selectable bus modes provide both big and little endian byte ordering and a clean interface to standard microprocessors. The linked-list buffer management system of DP83934CVUL-25 offers maximum flexibility in a variety of environments from PC-oriented adapters to high-speed motherboard designs. Furthermore, the DP83934CVUL-25 integrates a fully-compatible IEEE 802.3 Encoder/Decoder (ENDEC) and a Twisted Pair Interface which provide a one-chip solution for Ethernet when using 10BASE-T. When using 10BASE2 or 10BASE5, the DP83934CVUL-25 may be paired with the DP8392 Coaxial Transceiver Interface to achieve a simple 2-chip solution.

For increased performance, the SONIC-T implements a unique buffer management scheme to efficiently process receive and transmit packets in system memory. No intermediate packet copy is necessary. The DP83934CVUL-25 buffer management uses three areas in memory for (1) allocating additionaldescriptors to the memory resource area. The transmit buffer management uses two areas in memory: 1. indicating status and control information; 2. fetching packet data. The system can create a transmit queue allowing multiple packets to be transmitted from a single transmit command. The packet data can reside on any arbitrary byte boundary and can exist in several non-contiguous locations. resources, (2) indicating status information, and (3) buffering packet data. During reception, the DP83934CVUL-25 stores packets in the buffer area, then indicates receive status and control information in the descriptor area. The system allocates more memory resources to the DP83934CVUL-25 by adding
