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

Abstract

We design a specific Ethernet network interface card (NIC) for accelerating the 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 50MHz 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 0.35um cell-based design of the specific NIC system are given.
