Xilinx在5G网络中开发了用于O-RAN（Open Radio接入网络）分布式单元（O-DUS）和虚拟基带单元（VBBU）的FPGA的PCIe加速器卡。
T1卡是使用相同的FPGA和IP建造，已在5G网络中部署，并且是唯一提供O-RAN Fronthaul协议和第1层卸载的PCIe卡。FPGA的卸载处理减少了系统中所需的CPU核心数，并提供更大的5G吞吐量，同时降低整体系统功耗和成本。
The demand for O-DU and vBBU solutions is rapidly increasing because they provide an open and standard platform for a wide range of 5G virtualized services. The T1 card is a small form factor, single-slot card that can be plugged into standard x86 or non-x86 servers to achieve the real-time protocol processing performance required for 5G virtualized O-DU platforms.
它卸载了使用硬化的LDPC和Turbo编解码器，速率匹配/去匹配，HARQ缓冲区管理以及更多，用于运行其他服务的处理器内核的通道编码/解码，包括通道编码/解码。T1卡通过生态系统合作伙伴提供包括O-RAN FRONTHAUL和5G NR第1层参考设计的CORNKEY解决方案，以及预先验证的软件来简化5G部署，以使运营商，系统集成商和OEM能够快速到达市场。
“随着Xilinx在数据加速器市场的经验中，我们很高兴能够看到他们的扩展进入5G Telco加速卡，”诺基亚边缘计算平台头部Pasi Toivonen说。“我们在诺基亚的机身设计团队期待着继续与Xilinx一起使用，看看这些令人兴奋的新选择和不断增长的5G市场的能力。”
The offloading of critical channel coding functions from the CPU to the T1 card delivers up to 45x encoding and 23x decoding throughput improvement relative to the same server without acceleration. The T1 card enables the use of fewer CPU cores, driving down system cost and overall power consumption. Additionally, for O-RAN fronthaul termination, it can process multiple sectors of 5G NR 4TRX at 100 MHz OBW with its 50 Gbps of optical ports. The Fronthaul and L1 bandwidths are matched for optimal scalability; the more towers you want, the more cards you add to the server.
“The trend toward network virtualization and O-RAN has given us an opportunity with the Xilinx T1 Telco Accelerator Card to drive the next steps of disaggregation of standard networks, enabling our expansion into every corner of the 5G market,” said Dan Mansur, vice president of marketing, Wired and Wireless Group, Xilinx. “Working closely with our ecosystem partners, Xilinx hardware, IP and software are leading the innovation and realization of 5G O-RAN networks.”
“随着5G基础设施投资继续增长以支持新的和更高的带宽服务，提供可以提供更大的系统加速的解决方案，以满足日益增长的规模和带宽要求至关重要，”市场研究公司的固定和移动基础设施的实践领导者表示omdia。“随着O-RAN和虚拟化的不断增长的兴趣兴趣，Xilinx T1 Telco Accelerator卡是一种引人注目的解决方案，可以充分利用这种需求，同时也能够实现边缘处的软件和服务等重要领域。”
T1卡现在可用，现在对全球客户进行抽样。预计2021年初预计产量产量将会。
