局域网IP电话机主芯片的EDA设计与FPGA实现（接收部分）
摘要
本项目完成的是局域网IP电话机的设计与FPGA实现。系统以Altera公司的ACEX 1K系列的FPGA和快速以太网控制器RTL8201L和语音编解码芯片MSM7702-3为核心构建了数据处理主板和以单片机为控制器的拨号显示子板组成。数据处理主板的核心任务，包括语音数据处理、以太网帧处理、协议处理、呼叫处理等。拨号显示子板则完成通话前的显示用户所拨过的IP地址，通话期间网络状态的显示等等。本文首先介绍了局域网IP电话系统和TCP／IP协议等相关原理，然后着重介绍了FPGA的相关知识。在第四章，仔细讲述了基于FPGA的系统硬件总体方案，紧接着在第五章详细阐述了系统中FPGA的具体实现。我在项目中完成的工作：与项目组成员合作制定系统方案及根据要求选择芯片，设计数据处理主板，制作PCB板并加以调试；数据处理主板中的局域网IP电话机主芯片中接收部分的FPGA设计、仿真和调试。经过仿真调试证明，局域网IP电话机达到了设计要求的性能指标。
The design and FPGA implementation of LAN IP telephone has been completed in this project. The system is consist of the Main data processing board which is based onthe FPGA device and fast ethernet phyceiver RTL8201L and A- law PCM data encoder and decorder chip MSM7702-3, and the dial-up and display board which is based on MCU.The main board would carry out the core task of data processing, such as voice data packing and unpacking,the ethernet frame processing ,protocol processing,call processing,etc.the dial-up and display board would carry out the task of display the IP address which is input by consumer and status of network during talk period from the main board,and so on.In the paper the system of LAN IP telephone and the TCP/IP protocol is introduced firstly, then the FPGA device is stated.After that the FPGA-based hardware scheme is introduced in detail in chapter four. In the fifth chapter the Implementation of FPGA is introduced in detail. In the design of LAN IP telephone, the author has participated in the follow works: the systemdesign; Select chips, make the schematic circuit and PCB board of the main data processing board and debug it.the FPGA design, simulation and debugging of receiving part of LAN IP main chip. This systemhas been tested and verified and met the design requirement.
