基于SOPC的1553B总线接口逻辑设计

Design of 1553B Bus Interface Logic Based on SOPC

针对1553B总线协议控制器基本依赖于进口专用芯片现状,提出了以Xilinx公司Virtex-II Pro FPGA为核心实现1553B总线接口逻辑的系统设计方案。采用SOPC技术,将PowerPC 405硬核处理器与总线接口逻辑集成在一片FPGA上,从而使系统集成度高、功能强大、扩展性强。通过测试表明,系统工作稳定可靠,满足1553B总线协议标准。

According to the present situation of 1553B bus controller which is basically depending on the special imported chip, this paper puts forward the system design scheme that bases on taking Xilinx company＇s Virtex-Ⅱ Pro FPGA as centre to realize the 1553B bus interface. Integrating PowerPC 405 hard-core processor and bus interface logic on a FPGA by using SOPC technology, thus this design makes the system has high integration, powerful function and strong expandability. The test result indicates that the system is stable and reliable in work and can meet the standard requirement of 1553B bus protocol.
