摘要
针对ITU-T G.984相关协议较复杂、实现难度大、涉及面广,GPON系统FPGA设计过程中采用分层的设计方法。MAC层为GPON系统的核心层,基于通用成帧协议的TC层可封装多种业务,研究了TC层协议和TC层帧结构,针对成帧子层提出了模块化设计方案。在Quartus Ⅱ环境下,以Arria GX EP1AGX60DF780C6为目标器件,通过硬件描述语言Verilog HDL语言,完成了MAC层的FPGA实现和整体仿真。
Due to the complexity of ITU-T G.984 related Recommendation and difficulty of implement, so we adopts hierarchy method in the design process. According to the layered structure of GPON, MAC is the core layer of GPON system, and layer TC which is based on generic framing protocol can packet a variety of businesses. This paper studies the protocol and frame structure of layer TC, and puts forward a modularized proposal focused on the framing sub-layer. In Quartus II and taking Arria GX EP1AGX60DF780C6 as the target device, it realizes the overall simulation of the framing MAC-layer under FPGA by using Verilog HDL.
