发布时间：2018-08-26 18:36
【摘要】：现场可编程门阵列FPGA主频比较高，能够满足高速数据处理的要求。高端的FPGA一般都支持几百兆的频率，处理信息的能力更强；FPGA主板的运行更加稳定，可以处理比较复杂的问题。 FPGA的应用已经从过去通信基础设备这一非常窄的领域迅速扩展到了今天非常广泛的应用领域。 技术的进步提高了互联网在经济发展中的重要性，宽带服务的可用性、质量和竞争力已经成为并将继续成为许多国家和地区发展的关键问题。目前，我国宽带网络发展的瓶颈在于接入网部分，提高网络的带宽关键在于提高接入网的带宽。 本文首先介绍了HFC网络的特点及其发展，引出了目前处于研究前沿的HFC接入技术EPoC和DOCSIS3.1。比起传统的接入技术，新一代的HFC接入技术EPoC和DOCSIS3.1具有更高的吞吐量，，更高的频谱利用率，是未来几年接入技术研究发展的方向。本文从系统结构上介绍了EPoC和DOCSIS3.1，并分析了它们的MAC层协议和物理层协议，讨论了DOCSIS3.1MAC层FPGA实现方案，集中研究了DOCSIS3.1MAC层中几个关键模块的FPGA实现，并给出了详细的设计方案。最后文章介绍了DOCSIS3.1MAC层的测试，并对测试结果进行了分析。
[Abstract]:Field Programmable Gate Array (FPGA) has high main frequency and can meet the requirement of high speed data processing. High-end FPGA generally supports several hundred megabytes of frequency and can handle more complex problems because of its stronger ability to process information and more stable operation of the motherboard. The application of FPGA has rapidly expanded from the narrow field of communication infrastructure to a very wide range of applications today. Advances in technology have increased the importance of the Internet in economic development. The availability, quality and competitiveness of broadband services have become and will continue to be key issues in the development of many countries and regions. At present, the bottleneck of the development of broadband network in China lies in the access network, and the key to improve the bandwidth of the network is to improve the bandwidth of the access network. This paper first introduces the characteristics and development of HFC network, and leads to the HFC access technologies EPoC and DOCSIS3.1., which are currently in the forefront of research. Compared with the traditional access technologies, the new generation of HFC access technologies, EPoC and DOCSIS3.1, have higher throughput and higher spectral efficiency, which is the direction of research and development of access technology in the next few years. This paper introduces EPoC and DOCSIS3.1, from the system structure, analyzes their MAC layer protocols and physical layer protocols, discusses the implementation scheme of DOCSIS3.1MAC layer FPGA, focuses on the FPGA implementation of several key modules in the DOCSIS3.1MAC layer, and gives a detailed design scheme. Finally, the test of DOCSIS3.1MAC layer is introduced, and the test results are analyzed.
