基于SOPC的嵌入式系统设计

针对传统片上系统（sOc）解决方案在成本、体积及功耗等方面的缺点，以转换设备为背景，提出了一种基于可编程片上系统（SOPC）的设计方法，着重讨论了系统硬件平台的设计及应用软件的开发。设计以FPGA为核心，构建了基于NiosII软核处理器的SOPC系统，在NiosⅡ集成开发环境下开发出系统的应用软件。与传统方案统相比，该方案拥有更高的集成度、以及较小的体积和功耗。

Design and Application of Embedded System Based on SOPC Techniques

With a certain converter as background, a design based on SOPC system is introduced aiming at the shortcomings of traditional system on chip （SOC） sohition in cost, volume and power comumption. This paper emphasizes the design of hardware platform and development of application software. Regarded FPGA as the core, a SOPC system is built based on Nios II soft-core processor and application software is developed in Nios II integrated development environment. Compared with the traditional design, the present design has small volume, low power consumption, and high integration.
