摘　　要：为了提高计算机系统数据处理能力,防止数据丢失现象,减小接口板空间,同时方便接口模块的修改、扩展和升级,提出了一种基于Nios II软核处理器的智能1553B接口软核实现技术。系统设计以软硬件协同工作的形式实现。硬件设计是通过在一片Altera公司Cyclone II系列的FPGA芯片上配置Nios II软核处理器、PCI接口、存储器接口、自定义接口逻辑等来生成SOPC,最后在FPGA外添加外围总线控制器芯片来实现。以硬件设计为基础,以软件设计完成1553B数据传输功能。由于采用了软核设计技术,使得系统具有了设计灵活、集成度高、低成本等优点。In order to improve data processing capability of computer system,prevent the phenomenon of losing data,decrease interface board,amend,extend and upgrade interface module,this paper introduces a soft-core realization technology of intelligent 1553B interface based on Nios II soft-core processor.The system design carries out by the approach of software cooperating with hardware.In the part of hardware design,SOPC is built on an Altera Cyclone II series FPGA according to configure Nios II soft-core CPU.PCI interface,memoryinterface,custom interface logic and so on,which combines with peripheral bus controller chips to achieve hardware design.Based on this hardware design,software design achieves 1553B data transmitting function.Due to using soft-core design technology,the system has high design flexibility,low cost,high integration and such advantages.
