摘要
以网络化实验教学为背景,设计了一种基于Nios Ⅱ软核处理器和嵌入式实时操作系统的网络化实验教学数据采集系统。利用Quartus Ⅱ及SoPC Builder开发工具,对Nios Ⅱ CPU硬件资源进行重配置,自行定制CPU,并根据应用需要组建外围硬件接口,完成了一个基于FPGA的高性能嵌入式硬件系统的设计。采用嵌入式实时操作系统μC/OS II,为应用系统的实时性和人机交互功能提供了保证。实践表明,该应用方案具有功能可扩展和硬件可升级等优势,具有很好的应用潜力。
With the networking experimental education as background, the data acquisition system of networking experimental education based on Nios Ⅱsoft-core processor and embedded real-time operating system has been designed. By adopting Quartus II and SoPC Builder developing tools, the hardware resource of Nios ⅡCPU is reconfigured, and the CPU is customized. In addition, the hardware interfaces are established in accordance with the requirements to complete the design of high performance embedded hardware system based on FPGA. With help of embedded real-time operating system μC/OS Ⅱ, the real-time performance of the application system and man machine interactive function are guaranteed. The practice shows that this application scheme offers expandability of functions, and upgrade possibility of hardware, as well as excellent potential applicable prospects.
