摘要
1553B总线是美国军用标准MIL STD 1553B所定义的一种串行数据传输总线。文中研究该总线上传输的数据格式并使用VHDL语言对其进行仿真。此外,使用了基于FPGA的电路模块实现双相曼彻斯特码的编解码器。最后,在此电路模块上建立Nios2软核对该总线上的数据通信进行实时调度。
1553B is a serial data bus defined by American military standard. Data format of the bus and its VHDL simulation are discussed in this paper. Furthermore, the implementation of manchester ｜｜ bi-phase encoder and decoder based on FPGA is also described. Finally, a Nios2 soft core is built in the FPGA to schedule data communication of the bus.
