摘　　要：曼彻斯特码作为一种数字编码技术,具有自带时钟、无直流分量等优点,在数字通信系统中具有广泛的应用。本文在分析曼彻斯特编解码原理和1553B总线协议以及收发器HI-1573工作时序的基础上,利用ISE14.7开发环境,采用VHDL语言,基于Xilinx公司Spartan6型FPGA实现通用型和可定制的曼彻斯特Ⅱ型编解码器设计,并通过ISE Simulator和XST进行时序仿真和综合优化,仿真结果验证了设计方案的逻辑功能。最后搭建UART硬件测试平台,验证了设计方案的硬件可实现性。As a digital encoding technology, Manchester code has a wide application in digital com- munication system, with advantages such as build-in clock, no DC component and so on. Based on the a- nalysis of the Manchester encoding and decoding principle, 1553B bus protocol and the working sequence of HI - 1573 transceiver, this article designs and implements a versatile and customizable Manchester ]1 code in VHDL language on the Xilinx Spartan6 FPGA, with the software ISE14.7. And then, the results of timing simulation and synthesis with the ISE Simulator and XST indicate that the logic function of the design is achieved. Finally, with the UART hardware test, this article verifies the hardware implementa- tion of the design.
