The core is widely used in applications where ultra-low, deterministic latency and high performance of throughput are required, such as video, image and audio streaming over Ethernet, IP cameras VOIP and smart phones, high frequency trading system, high-speed communication data centers, device monitoring and control over IP networks. It works as a key component in network architecture. The 100G MAC and PCS Core has been evaluated on Xilinx platform. The core is highly pipelined and optimized to achieve ultra-low latency and high performance. The core implements RS FEC as defined in IEEE 802.3bj Clause 91 with independent bit error detection and bit error correction. It implements configuration, control, status, statistical information collection and it supports VLAN tagged frame defined IEEE 802.1Q.
