摘要
在研究国外先进协议芯片的基础上,提出了一种基于SOPC技术的1553B总线BC/RT/MT通用接口的设计方法;通过外加模拟收发器,将NIOSⅡ软核处理器与各种功能模块集成在FPGA内部,实现了1553B总线通用接口功能;最后以TMS320LF2407作为宿主机,在NIOSⅡIDE开发环境中针对通用接口BC/RT/MT工作模式分别进行了整体测试,初步测试表明通用接口能够完成1553B总线通讯任务;SOPC技术实现了硬件设计软件化,大大增强了总线接口电路设计的灵活性,缩短了设计周期,提高了系统性能与通用性,有利于系统的扩展。
Based on SOPC, a new 1553B interface used as BC/RT/MT has been designed. Adding the exterior analog transceiver and integrating the NIOS Ⅱ CPU and other functional modules in FPGA, the requirements of the 1553B universal interface are satisfied. Finally, system test has been taken in NIOS Ⅱ IDE, and the test shows that the universal interface could achieve the bus communication tasks. The application of SOPC technology increases the capability, flexibility and adaptability of the design, and would benefit improving of the system.
