Design and implementation of a video-oriented network-interface-card system

We design a specific Ethernet network interface card (NIC) for accelerating video delivery by offloading the overheads of protocol headers identification/appending and CRC/checksums calculation, and speeding video bit streams with a dedicated video interface. Compared with the same operations of a 50 MHz ARM micro-controller, the NIC system saves 47,000 ns per frame. This NIC card also supports the coexistence of the IPv4 and IPv6 standard for the future extension. Both FPGA prototyping and 0.35 /spl mu/m cell-based design of the specific NIC system are given.
