基于Nios Ⅱ的嵌入式系统设计

Design of Embeded System Based on Nios Ⅱ

为解决传统终端设备在成本、体积、功耗等方面存在的问题，基于Nios Ⅱ的软核处理器技术，提出了嵌入式系统设计的解决方案。文章以FPGA为核心，构建了基于Nios Ⅱ的软核处理器系统的设计方案，并阐述了硬件平台和系统的软件设计；与传统方案比，该方案拥有更高的集成度、数据交互速率，以及较小的体积功耗和成本等优点。

A design based on SOPC system is introduced aiming at the shortcomings of traditional system on chip solution in cost, volume and power consumption. This paper emphasizes the design of hardware platform and development of application software. Regarded FPGA as the core, application software is developed in Nios Ⅱ integrated development environment. The result indicates that compared with the traditional design, the present design has small volume, low power consumption, and high integration.
