摘要
在航空电子系统中,经常需要将1553B总线和ARINC429总线进行双向数据转换。本文利用可编程逻辑器件(CycloneFPGA)和硬件描述语言(VHDL),采用自顶向下的模块化设计思想、可编程的时钟使能方案来实现1553B-ARINC429总线转换器的设计,并通过QuartusII软件对本设计的整体性能和时序进行分析验证。其结果表明,该设计转换性能可靠、准确率高,大大提高了芯片资源的利用率,满足了系统的要求。同时本通用的设计方案还可以兼容更多的标准,实现多种航空总线数据的通信。
In aero electronic system, it is regular to make bidirectional data transform between 1553B bus and ARINCA29 bus. In this paper, the design of 1553B-ARINCA29 bus Transformer is based on programmable logic device （Cyclone FPGA） and hardware description language （VHDL）. The modularization design ideal from top to down and the programmable enabling scheme are used in this project. The whole performance and timing of transformer are analyzed via Quartus II software. The result shows that this design has high transformation ability and accuracy rate. It improves the resource use factor of the chip and meets the need of system. At the same time, this universal design method can be compatible with many other standards, realizes the communications of many kinds of aero bus data.
