基于FPGA的曼彻斯特编码DSG的设计与实现

Design and Implementation of Manchester Encoding DSG Based on FPGA

利用可编程门阵列(FPGA)技术的可重构性与灵活性,设计实现了一种数据率可调、具有曼彻斯特编码功能的数字信号发生器。该信号发生器结合了数字信号发生器和曼彻斯特编码的优点,弥补了信号发生器不具备曼彻斯特编码功能的不足。该系统采用硬件描述语言VHDL进行设计,使用Quartus II 8.0进行综合布线,最终适配到DE2开发板并用示波器等设备进行了验证测试。整个设计硬件结构简单、占用逻辑器件资源少、可靠性高、灵活性强、适应性好,具有一定的理论价值和应用前景。

Digital Signal Generator, as the typical representative of general Digital Signal source, plays a very important role in Modem Data Testing fields. Because FPGA technology is reconfigurable and flexible, one designed and implemented a configurable Digital Signal Generator with function of Manchester encoding by using hardware development tools Quartus II 8.0. The system uses hardware description language VHDL to design, locating and wiring on Quartus II 8. O. For the sake of verifying the feasibility of this design, one adapted it to the DE2 board, and tested with an oscilloscope and other equipments. The whole design has a simple hardware structure, less logic devices resources were occupied, and with high reliability, flexible and adaptable. This research has some theoretical value and application prospect.
