摘　　要：FlexRay通信系统是先进汽车控制应用的新兴标准,它为汽车应用提供高速串行通信、时间触发总线和电子设备之间的容错通信。为了适应星载计算机低成本、可伸缩、可重构、快速组装等发展需求,可将FlexRay通信系统应用到宇航计算机系统中。针对星载平台产品快速定制的应用需求背景,设计了基于FPGA的FlexRay总线和LocalBus总线转换模块控制器,实现星载电子系统的按需定制和快速动态组装。在Xilinix工具上对转换模块进行了VHDL仿真,仿真结果表明本转换模块满足设计要求。The FlexRay communication system is an emerging standard for advanced automotive control applications. It provides high-speed serial communications, time-triggered buses, and fault-tolerant communications between electronic devices for automotive applications. In order to meet the development requirements of low-cost, scalable, reconfigurable, and rapid assembly of spaceborne computers, the FlexRay communication system can be applied to the aerospace computer system. Aiming at the background of application requirements for rapid customization of spaceborne platform products, FPGA-based FlexRay Bus and LocalBus conversion module controllers are designed to realize on-demand customization and rapid dynamic assembly of spaceborne electronic systems. The VHDL simulation of the conversion module is carried out on Xilinix tools, and the simulation results show that the conversion module meets the design requirements.
