App Note AN007, Software-Defined NIC…, has been newly issued. A software-defined full duplex 10baseT Network Interface Controller is implemented as a team of nodes controlling transmit and receive signal pins directly. The signals are conditioned by minimal electrical interface circuitry. External transmit timing is used. The team is designed to function as a memory-mapped device but may be stripped down for direct use by other node teams. This NIC is supported by the polyFORTH® TCP/IP package on the host chip of the EVB001 Evaluation Board.
