The implement of manchester coder in MIL-STD-1553B bus based on FPGA

随着MIL-STD-1553B总线在航空航天和军工领域的广泛应用,为了降低该总线的应用成本和提高应用开发的灵活性,设计并实现该通信协议的曼彻斯特编解码器。通过分析1553B协议和曼彻斯特II型码编解码原理,确定出编解码器的整体框架,利用ISE14.1开发环境和Verilog HDL硬件描述语言对其设计实现,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,最后在Xilinx Spartan6系列XC6SLX16型号FPGA 上进行了实现。在深入分析1553B协议的基础上,对编解码器的工作原理、工作过程、逻辑设计及仿真验证进行详细介绍。

With the abroad application of MIL- STD- 1553B in aerospace and military fields,the Manchester codec of the 1553B communication protocol is designed and implemented,in order to reduce the application cost and improve the flexibility of development. The overall framework of the codec is determined through analyzing the 1553B protocol and the Manchester II code encoding and decoding principle. Using the ISE14.1 software development environment and the Verilog HDL hardware description language design the codec. The results of timing simulation and synthesis with ISE Simulator and XST verify the logic function of the design. Finally,the design is implemented on the Xilinx Spartan6 series XC6SLX16 model FPGA. Based on the analysis of the 1553B protocol,more details about the working principle,working process,logic design and simulation verification of the codec are present.
