摘　　要：设计了1553B和ARINC429总线实时协议转换系统。系统硬件部分采用"MCU+FPGA+外围芯片"进行构建;软件部分是将嵌入式实时内核μC/OS-II移植到DSP控制器上从而构建一个低成本的通用嵌入式实时软件平台,基于此平台以C语言和汇编语言在DSP集成化软件开发环境CCS上加以实现。对协议转换系统进行了测试和联机验证,结果表明该系统完全符合设计要求。A real-time protocol converter between 1553B and ARINC429 is designed. Its hardware is built with the method of ＂MCU＋FPGA＋ Peripheral Chips＂. A universal embedded real-time software platform is developed for real-time ability requirements by porting the embedded real-time kernel μC/OS-Ⅱ to the DSP controller. Based on this real-time software platform, the soft- ware of protocol converter is realized in CCS with C and assemble language. Protocol converter is also verified by constructing an experiment system, and the result shows this converter satisfies the design requirements fully.
